Air conditioning leaks

Posted by Willie – March 25, 2011

Auto air conditioning leaks are the most common cause of automotive AC systems not blowing cold air.

What can happen is the vehicles refrigerant gas will leak out and reduce the total pressure in the system. Then the low-pressure cut out switch will disengage the compressor when the low side is detected below 25 psi.

This safety feature is to protect the compressor itself. I have seen mechanics bypass the low cut out switch for testing. This should never be done and is not recommended. 

 

 

The car AC compressor can be damaged quickly and spread metal flakes through the entire air conditioning system. For these reasons replacement is a very expensive auto repair.

Note that when the system pressure is low and the compressor clutch disengages it is just like having the AC switch turned off completely.

Therefore testing for air conditioning leaks properly is one of the most important tasks when it comes to troubleshooting automotive air-conditioning systems. Keep in mind that over a long period of time, all air conditioners will lose or leak out some refrigerant.

Even in systems that are in good condition. They say that on average, an AC system could lose up to15% of refrigerant a year and this would be considered a normal condition. Keeping in mind that a new vehicle may have been assembled up to 12 months prior to the sale, leaving the Air Con system already short of the required amount of refrigerant on the day of sale.

Finding auto air conditioning leaks

As I mentioned before in previous articles about how the air-conditioning system works. The Refrigerant (Gas) contains the oil necessary to lubricate the compressor.

The presence of oil around a fitting or line is a strong indication of a refrigerant leak. So my first step in air-conditioning leak diagnosis is to perform a solid visual inspection of the entire system.

 
 

Although this is always my first step for diagnosing Refrigerant leaks, it is not always effective in finding the problem. In fact, this visual inspection will only uncover large to extremely large leaks.

And by far the most common air-conditioning problem would be small leaks that allow Refrigerant to escape over long periods of time. So to follow will be methods to detect these small leaks. 

Fluorescent dye auto leak detectors

 

Most Garages that I have visited use fluorescent dye tracer system for finding stubborn leaks. And if they are not using it, I strongly urge them to start.

To find refrigerant leaks using the fluorescent tracer system, you first have to install the fluorescent dye into the cars air-conditioning system. UV dye should be injected every time an Air Con system is serviced which will ensure an easy detection of any leaks that may form in the system in the future.

Always follow the instructions and do not install too much dye! Different refrigerant dye leak detectors will accomplish this in different ways.

In olden day it was acceptable to inject dye into an AC system, if the system was known to have a leak, and then fill it with Refrigerant, run the air-conditioning system for several minutes to distribute the dye evenly. Then you put on your yellow glasses and examine the system with a fluorescent Light. This practice is now illegal. You cannot fill an AC system with Refrigerant if you know that the system is leaking. So for UV detection the dye must be injected when servicing the system.

 

 

The fluorescent dye shows up easily wearing the yellow glasses. Sometimes the results will yield something you do not want to find. For example, on a demo some time ago, I used the fluorescent dye system, as the dye had been injected the last time the AC system was serviced; I did not see any leaks in the engine compartment.

But when I examined the evaporator case inside the vehicle, the fluorescent dye was laying in a large puddle on the bottom of it. This meant the evaporator itself needed replacement. Not a fun job on most vehicles. 

Most modern AC service stations will now add UV dye automatically when servicing AC systems ensuring easy leak detection should leaks develop.

Nitrogen Leak detection

New regulations have changed the Automotive AC industry and the way we detect leaks has also been influenced. As outlined above it is now illegal to charge an AC system with Refrigerant, (gas) if you know that system has a leak. So if UV Dye has not been previously injected the next best way to locate leaks is using Nitrogen. Air should never be used to pressurize an AC system as air contains large amounts of moisture, which is detrimental to an AC system. Nitrogen on the other hand is completely safe.

There are 2 pieces of equipment you will need. A nitrogen charge kit and a listening probe kit.

First the AC system needs to be pressurised with nitrogen, and regulated to sustain a constant pressure.

Listening Device

Nitrogen Charge kit

Once pressurised the listening probe is now used to locate the leak, nitrogen escaping thru any leaks will easily be detected by the listening probe. Safely locating the leak.

See http://www.ageltd.ie/index.php?route=product/category&path=36_68 for more details.

If you want more information regarding the requirements now in law for any one involved in Automotive AC give me a call. It is now illegal for any one to handle R134A Refrigerant without a proper qualification; fines of up to €3,000.00 are applicable.  087 9172409

Diesel Engine Analyses – Part II

Posted by Willie – March 25, 2011

 If you missed last months issue see it now first at www.ageltd.ie    latest news.

Diesel Injections and Pollution.

Modern Diesel injection systems have evolved and changed a great deal in recent years enabling huge reductions in pollution and improved engine efficiency. This is mainly due the improved injection systems now used. By raising the injection pressure of the diesel, the fuel is atomised better, and this in turn improves combustion. If you think of a fuel flowing freely from a hose it is almost impossible to ignite as the flow of fuel is to large, if on the other hand you were to place your thumb over the end of the hose, causing a very fine spray of fuel this now will ignite with very little effort as it is in droplet form and it can easily avail of the oxygen from 360 degrees to ignite. So by using a pump injection system the diesel injected into the cylinder is atomised leading to more efficient combustion. Pump injection systems can reach pressures of up to 2000 bar.

Common Rail CP1 pump components

                                            

Pump

 

    High Pressure 1400/1600                          Low Pressure 2.5 bar

IMA Coding

With such high pressure being used it is important that the correct amount of diesel is injected into each injector ensuring the smoothing running of the engine.  The system therefore requires memorisation of each single code in the control unit whenever it or one of the injectors is replaced. This procedure is only possible with the use of an appropriate diagnostic tool. 

With so many different vehicles on the road today it is impossible to have one diagnostic tool to cover all engines. Some diagnostic tool will be focused on European Vehicles while others will focus on Asian Vehicles. What tends to happen with diagnostic tools is most vehicles will be listed as being available to diagnose, but the problem is that there will be very little coverage or function on certain makes, making functions such as injector coding impossible. To over come this problem it is now widely accepted that 2 diagnostic tools are required to cover most of the demands of the modern vehicles. I would recommend that for Asian Vehicles you use the Carmanscan AT diagnostic tool.

CARMANSCAN AT

This is an excellent tool, with colour touch screen and easy to follow functions there is almost nothing this tool won’t do when it comes to Asian Vehicles. Injector coding, Key coding, auto scanning, and ecu coding ECT. It has European Vehicle coverage also, and it is very very good also on Audi, WV, Soda, Seat BMW, Mercedes ect but it strengths in functionally are in Japanese and Korean Vehicles. And to accompany this tool help to cover all problems I would recommend the OTC ( Tecno –Test) Reflex.

OTC REFLEX

    

This tool has almost dealer level functions for Renault, Citroen, Peugeot, Opel, ECT. With function like Injector coding, ECU coding, ECT it is a perfect partner to the Carmanscan AT and between them should ensure the best possible diagnostic power available.

 For more see  http://www.ageltd.ie/index.php?route=product/category&path=35_51  Hand held diagnostic tools.

With the right diagnostic tool injector coding can be a simple step by step procedure but a very important one.

IMA Classification

The basic difference of the classic unijet Common Rail systems was it used different injection pressure and used a single code identification process for injectors. IMA Classification on the other hand requires that an alphanumerical code of 9 figures, (IMA Code) be used instead of the single numbers of the earlier systems.

The aim of “IMA” classification is to improve engine performance and to control the emissions by managing the minimum construction differences of each injector using software and the engine control unit. Each injector is classified by assessing its performance in 7 functioning points based on various pressure levels and injection times, so as to simulate a variety of functioning situations of the engine. Each control point has a name,

  • Main at full load
  • Main at emissions
  • Pilot at emissions
  • Pilot at full load
  • Pilot at idle
  • Combi at 800 bar
  • Combi at 300 bar

Once these entire tests are carried out the classification code will be applied to that injector. This code will then need to be programmed to the ECU when the injector is fitted to a vehicle to ensure smooth running of the engine and control of the emissions.

  

Air Mass Meter

The Air Mass meter is assembled directly to the out put of air filter box. This allow for the measurement of air flow and air temperature to be measured. The flow of air, going into the the turbo compressor, is measured using a hot film sensor. Once measured this information is feed directly to the Engine Management ECU along with the air temperature which is measured using an integrated NTC so that ECU is perfectly informed of the mass of incoming air and can thereby dose the exact quantity of fuel to inject into the cylinder. The output signal of the meter varies with engine load and this signal is used by the ECU to calculate the air flow rate for management of the exhaust fumes.

Common Problems with an Air Mass Meter.

A faulty Air Mass meter signal will cause the car’s computer/ecu to give too much or too little fuel to the injectors. If the car ecu detects that there is either an erratic signal or none at all it uses a default value to keep the engine running. The ecu takes the engine load and speed, modifies the value for some fuel and engine temperature readings and Air Mass Meter value, etc to determine fuel injection timing and metering. A diesel car can run without the Air Mass Meter but performance will be poor and the engine will feel sluggish and you will feel a lack of power. The Air Mass Meter might produce a sudden reduction in car power but the normal failure mode is a gradual loss of power over several weeks.

     

  1. Electronic control circuit
  2. Sensitive element with build in aspirated air temp sensor
  3. Metal Support plate
  4. Plastic support plate
  5. Air temperature and mass reading position

If after the car has warmed up and there is lack of power and you find power is restored by shutting the car off and turning it back on after a short while it could be an indication that the circuit joints within the sensor have degraded. The Air Mass meter could be slowly failing and contributing to power loss but if you suddenly go into limp mode, you have other problems. If you have constant low power it could be the Air Mass Meter. If you have an oiled type aftermarket air filter, excess oil may get onto the hot film sensor and damage the Meter.

It’s important to have an airtight intake hose after the Air Mass Meter because the amount of metered air won’t be correct if it’s leaking out of a disconnected or split hose! Air leaks are called vacuum or boost leaks. If these air leaks are not corrected first you could be changing the Air Mass meter for no reason. On easy and quick way to check if you have any leaks is to use a “Smoke Pro”. This will quickly locate any leaks and ensue an air tight fit. Again in case of replacing this part a diagnostic tool will be required.

Smoke Pro

Manifold Pressure Sensor

The manifold pressure sensor is mounted directly on the intake manifold. It is a linear sensor composed of a Wheatstone bridge. The pressure of the manifold warps the ceramic plate onto which the circuit is screen printed, altering it resistance. This is important information, together with the air mass meter, for deciding the quantity of diesel to inject into the cylinder.

At idle, the manifold vacuum is about 10 to 15 in. Hg (inches of mercury (Hg), a common unit used for vacuum), and at full-load state the vacuum is near 0 in. Hg. The MPS is designed to respond to two fundamental load conditions, part-load and full-load. Idle mixture is controlled by a special circuit in the ECU that senses the idle condition from the throttle position sensor (TPS). Part-load operation requires a linear response to load, and the mixture is a compromise between performance, fuel economy, and emissions. Full-load enrichment requires a transition from the part load response for enrichment to provide maximum power output, as the manifold vacuum drops to near zero.

Given the discussion above, the MPS response curve appears as follows:

  

 

To check the basic operation of the unit follow these simple steps,

Using a hand vacuum pump with a gauge, pull a vacuum of 10 in. Hg on the sensing port of the MPS. If a vacuum cannot be pulled or it leaks down (< 5 in. Hg in one minute), then the sensor is leaky and must be repaired. The usual causes of vacuum leaks are a cracked diaphragm, a leaky body flange seal (either an o-ring and/or a flange seal), or a leaky part-load stop seal (paper seal, unobtainable – gasket sealant may work). Some people have reported luck with repairing the diaphragm using solder or epoxy, or a sandwich of aluminium foil and RTV (!), but such a repair is not recommended. The diaphragm is fully flexed each time the engine is under full load (open throttle) and it is highly likely that any repair will only hold for a short while. The usual way of getting a repair is to do a rebuild exchange with either Performance/Automation or Automobile Atlanta.

If the vacuum test is passed, check the coil resistances. The primary coil is measured between terminals 7 and 15 and should measure about 90 ohms. The secondary coil is measured between terminals 8 and 10 and should measure about 350 ohms. Also check the coil isolation – there should be no continuity between either of the coils and the case. If any faults are detected the MPS is defective and must be replaced.

If both tests above are passed, then the MPS should be in good condition. However, it is possible that one or both of the aneroid cells have failed and are no longer sealed. This failure causes a rich part-load and idle mixture. Testing for a failed aneroid cell requires measurement of the inductance vs. vacuum characteristic of the MPS. The recommended inductance meter for this test is the Wavetek LCR55.

 

The slope of the part-load characteristic is compared to the calibration curves presented in this document. If the slope is significantly (~50%) less than the calibration curve, then it is likely that one of the cells has failed. Again if replacing this sensor a diagnostic tool will be required.

Diesel Engine Analyses

Posted by Willie – February 24, 2011

Recent figures have showen that Diesel Cars are now outselling petrol cars 3 fold. This is due to the reduced running cost of Diesel cars but also due to huge improvements made in recent years in Diesel Engines. We will over the next few months look closely at these improvements and give you a clear understanding of the different aspects of the Diesel Combustion Engine. 

Diesel Combustion 

Every diesel engine produces pollutants, the most important we will examine. Many factors contribute to the pollutants produced, namely 

The titre of the fuel mixture (proportion of fuel to combustion agents) 

The set point of the engine and the boundary conditions (speed, load, temperature of the engine, aspirated air and atmospheric pressure) 

The engine characteristics, (shape of the combustion chamber, layout of the aspiration ducts, type of power supply system, number of valves through which the fuel mixture enters the chamber and the gases are evacuated) 

Combustion inside the engine is not perfect and this generates substances which are poisonous to man and the environment. 

 

Pollutants – Management and treatment 

The most harmful pollutants present in the exhaust fumes of an engine are, 

Carbon Monoxide (CO), Hydrocarbons (HC), Nitrogen oxides (NOx) particulate. 

Post treatment systems of exhaust fumes used on modern engines almost completely destroy these harmful substances but not completely. 

Below is a list of pollutants produced by the engine and we can put these into 2 categories, Harmful and Non harmful. 

  

Not having to worry about the non harmful pollutants, new rules and regulations have regularly been introduced since 1993 to reduce these harmful pollutants. Many of these regulations put pressure on vehicle manufactures forcing them to develop better and safer diesel engines. 

Striving To Improve – New European Union Regulations 

  • Euro 1 Standard – 1993
  • Euro II Standard – 1996
  • Euro III Standard – 2000
  • Euro IV Standard – 2005
  • Euro 5/6 Standard – 2008

Many of the regulations enforced not only applied to reduce emissions but also instead on cleaner fuel. For instance in the Euro III Regulations it was also required to provide “Sulphur-free” diesel be available by 2005 and it was mandatory by 2009. Again all these regulations were geared to reducing harmful pollutants. 

Along with these regulations, improvements in the engine it self has also helped in reducing these harmful pollutants and one big improvement was the introduction of the common rail injector. 

Below is the outline of improvements made to the engines to comply with the various regulations introduced since 1993. 

Emission trends – Developments in Diesel Engines 

 

With the introduction of the common rail injector this helped to reduce the harmful pollutants due the improved method of the fuel combustion. 

Injectors THEN and NOW 

 

Common rail injectors are direct, (pictured on the right). The injector nozzle faces the combustion chamber. The swirl of the aspirated air is generated by the special contouring of the aspiration ducts and of the piston head. This improves combustion and again reduces emissions. If you look at the in direct injector (pictured left) the injector nozzle is facing the pre chamber, which has to then generate the swirl needed to make the fuel ignite. 

Principles of the Diesel Engine. 

The revs of Diesel engine are regulated by the quantity of fuel allowed to flow into the cylinder. To control this flow in stead of an accelerator throttle, an accelerator pedal potentiometer is used. In a diesel engine the air is free to enter and that is why it is said to function on “excess air”. Therefore the engine operates with the air coefficient of approx 1.45 – 1.55. It should also be noted that if this were not the case, the combustion of the diesel would be abnormal, which would lead to the generation of excess fumes from the exhaust. 

The EGR System – Exhaust gas recirculation. 

The EGR system is one most widely used to lower the emission of Nitrogen Oxide. It is well known that these pollutants increase considerably when the temperature in the combustion chamber reaches a high level so they need to be controlled. If the engine works at average loads it is possible to recirculate a quantity of exhaust fumes in the cylinder. There is therefore less aspirated air and as a result of this combustion too is less efficient, causing a reduction of the temperature and of the nitrogen oxides. Pursuant to anti-pollution legislation EURO 3-4, depending on the engine load and the signal coming from the accelerator pedal potentiometer, the electronic control unit limits the quantity of fresh air aspirated, actuating partial aspiration of the exhaust fumes, by regulating the aperture of the electronic EGR valve. 

The system allows part of the exhaust fumes (5-15%) to be aspirated in specific functioning conditions. The temperature peak in the combustion chamber is thus lowered, limiting the formation of Nitrogen Oxides (NOx)

The EGR solenoid valve (1) controlled by the injection control unit (2) acts to re-emit part of the exhaust fumes withdrawn by the exhaust manifold (4) for aspiration by the engine. A heat exchanger (3) allows partial cooling of the exhaust fumes, increasing the engine output in terms of volume.

  1. EGR Valve body                                                                          1.  EGR solenoid valve                 
  2. Inner Valve                                                                                 2. Injection control unit.
  3. Gas input from exhaust manifold                                                3. Heat Exchanger
  4. Gas output to aspiration manifold                                              4. Exhaust Manifold.

In diesel engines, to facilitate the spontaneous ignition of the diesel when it comes into contact with the hot compressed air present in the cylinder the injection pressure, generated by a mechanical pump, is increased. This results in an extremely fine spray of fuel being produced so that when the droplets come into contact with the hot air they vaporise and ignite easily.

 

Smoke from the exhaust is drastically reduced, the oxidation reaction is optimal and functioning of the engine is regular thereby enabling delivery of a high engine torque at all speeds.

Controlling the quantity of fuel injected

On the basis of the signals coming from the sensors and the mapped values, the control unit,

  • commands the pressure regulator
  • varies the “pilot” injection time throughout  the full range of revs
  • Varies the “main” injection time.

 

Watch out for next months issue where we will examine the common rail injection system, injector codeing, why it is very important, Air mass meters, Manifold pressure sensors, Lamdas, Catalyst, Particulate filters, FAP and DPF SYSTEMS, don’t miss it…..

 

  

 

Why Air Conditioning systems can smell and be harmful to your health

Posted by Willie – February 24, 2011

Servicing an Automotive Air Conditioning system is recommended to be carried out every 2 years. But since the Air Conditioning system is sealed, this service will do nothing to remove Mould fungi or Bacteria from the system, and this is what causes “Sick Car Syndrome”.  

 

For the past 4 years research conducted by the Georgia State University’s Environmental dept has been studying this problem, which in America, afflicts some 4 million vehicles, in every class from economy to luxury. The reason for this is, offending organisms, similar to Mould and Fungus that can grow in your shower or bathroom. But since cars are out on the road many more contaminants are introduced.  

Moisture condensation in the Air Conditioning system provide an environment perfect for mould, fungus, bacteria and other micro-organisms to grow. Odours associated with micro-organisms permeate the air duct system, sending these odours into the vehicles interior. 

 
 
 
 
 

Bacteria Spores 

 

Studies have also shown that bioaerosols incl mould is a common indoor pollutant and exposure to bioaerosols is associated with a wide range of health effects. Respiratory symptoms and lung function impairment are the most widely studied and probably among the most important. Moulds are a type of fungi. There are more than 1,000,000 species of mould and 200 different tyres which people are routinely exposed. Exposure to substantial amounts of mould and mould spores may contribute to skin, eye and respiratory irritation. 
Industry experts cite new vehicles (less than 4 years old) design as the cause. To increase AC System efficiency, they’ve made systems with more surface area, and the more surface area you have , the more room you have for moisture and for this junk to grow on. No fungi are known to cause infectious diseases but if you are allergic to these fungi you can have an allergy attack, or if you are mould sensitivity or asthma, they can bring on an asthma attack. Other common systems are headache or nosier. 
 
 
 

 
 
 
 
 

Bacteria and Mould build up the Evaporator  

 

 
 
 
 
 

Adding to the problem could also be blocked water run off. This run off is to allow moisture escape from the Evaporator, a blocked drain will lead to the evaporator not drying out creating an even better breading ground for bacteria and fungi to thrive. Once bacteria of mould take hold it will spread to all the duck systems and can also spread to the interior of the vehicles carpets ect. Some simple advice you can offer your customers to reduce mould build up is 
  •  The Air Conditioning should be run on the outside air setting as opposed to the recirculation setting as often as possible. This allows the system to pull in new air and get rid of old moisture.
  • The Max setting is going to give you recirculated air and should only be used on extremely hot days – and only for short intervals 
  •  Never the leave the AC set on MAX while the engine is off. This keeps the vents closed and doesn’t allow outside air to get in. The heat created by a closed system combined with the moisture produces a virtual greenhouse for bacteria and fungi
  • When you use the AC, there should be water draining from under the car. No water means that the evaporator run off is blocked, causing the evaporator to remain wet.

Apart from this advise you can also clean and deodorize the heating, ventilation and AIR CONDITIONING system and the vehicles interior with the AGE Ultrasonic cleaning system. 

 
 
 
 
 

Ultrasonic Air Con/ Vehicle cleaning system 

 

see http://www.ageltd.ie/index.php?route=product/product&path=36_50&product_id=135 

The Ultrasonic Air Con / Vehicle cleaner is uses in conjunction with the AC System on the vehicle. The recirculation selection is used and using ultrasonic technology, the A/C Cleaning solution is atomized into a fine mist that circulates through the vehicles hearing, ventilation and AC System and fills the vehicles interior. The ultrasonic mist created is designed to eliminate the unpleasant odours associated with mould, mildew, fungi and bacteria. The mist will also eliminate most common odours in the carpeting, upholstery and air bourn odours like tobacco, food and beverages. Designed to eliminate stale vehicle odours, this is an ideal tool to freshen up the interior of any vehicle to provide a fresh and clean smell. 
 
 
 
 

 

Spraying disinfectant into the air vents won’t kill these growths. The chances of anything making it into the system and still being effective are somewhere between slim and none. 
 
 
 
 
  

 

 

 

 

 

 

 

Nextek Introduces its Latest Carmanscan Multi Brand Diagnostic Tool Range

Posted by Willie – February 24, 2011

For over 17 years Nextech’s, Carmanscan Diagnostic tool’s  have built up it’s reputation as being a leader in the field of Automotive Diagnostic Equipment, and has not looked back since. Originally building OEM tools for Hyundai, Kia and Sanngyong, it soon put this…………

Vast knowledge and experience together and started production of Multi Band Diagnostic Tools. The Carmanscan VG and CII were the first multi brand diagnostic tools and they were a great success due to the fantastic coverage they offered for Japanese and Korean vehicles.

VG                                                                   C11

         

With continuing growth in sales, in 2000 Nextech posted its first overseas bond for 10 Million dollars, and constant communication with its distribution network Nexteck diagnostic tools soon became a market leader. Later in 2000 Nextech also set up an internet based car maintenance service.

Regular surveys were carried out with all Nexteck distributors to establish the most popular vehicles in different parts of the world and research and development was then focused on these results. After numerous surveys and consultations with Nexteck, it was clear that the Volkswagen Group, Renault, Ford, Citroen, Peugeot, Alfa Romeo, Fiat, Volvo, Opel, Saab, BMW and Mercedes need a lot of development for Ireland and the rest of Europe. Armed with this information Nexteck spent the next few years restlessly developing European software. To help speed up this process in 2006 Nexteck also opened a research and development operation in Amsterdam focusing on European car manufacture software development. Nextech also took note that a lot of Diagnostic Tool user do not feel the need to up date their tool every year, so to help its customers, Nextech adapted a no penalty fee. So if you decide not to re new your up grade after a year, your tool will NEVER SHUT DOWN. It will continue to work on the version of software installed. At any time in the future should you wish to re activate your up grade again, there is no fee for missed up dates, and the first up date installed will have all previsious versions included, this again is Nextech’s willingness to listen to its customers and help when ever possible.  As their data base increased it was necessary to up date their hardware. Increasing the memory size was essiantel but Nextech also included a larger screen and installed a battery in the new Carmanscan Lite launched in 2006. The battery was a very good addition to the tool as it prevented the tool shuting down if the iginition was turned during use and it was also now able to assist in locating the diagnostic socket in the vehicle as it had its own power supply. The easy to navigate buttons and exceptional build quality made the Carmanscan Lite an instant success.

The Carmanscan Lite has been one of the best selling tools (and still is) since its launch in 2006 and is still acknowledged as one of the easiest diagnostics tools to use and one of the most durable. Such was success of the Carmanscan range that between 2006 and 2007 over 4,300 units were contracted to Neo Systems Co Ltd, in Russia, K-Mart in Australia, Car Quest in America, Italy Motorscan and Ministry of Education in Poland.

Following on this success Nexteck introduced an up grade on their Carmanscan VG in 2008 with the Carmanscan VG+.

Adding a larger memory, brighter screen and longer life battery the VG+ was streets ahead of anything similar. It was a full multi brand diagnostic tool, a 4 channel scope with wiring diagrams and technical info also displayed. Immediately a contract was secured for 144 VG+ with METEOR Slovensko s.r.o. Nextech was now firmly established as a market leader in Automotive Diagnostic Equipment and this was even further acknowledged in 2009 when Nextech was contracted to supply Delphi Co, Ltd with OBD III Connector.

DON’T JUST INFLATE TYRES, INFLATE PROFITS

Posted by Willie – January 17, 2011

For years racing professionals have known that Nitrogen is better than air for inflating tyres.
Now Nitrogen can be better for your customer’s tyres and better for your profits.

Tyres filled with Nitrogen will last longer, loose less pressure and reduce fuel costs. To better understand how Nitrogen can achieve this lets first examine pressure.

Two of the main gases found in air, oxygen and carbon dioxide, contain very small molecules. Over time these molecules will escape thru the rubber tyre which reduces the pressure in the tyre. Pure Nitrogen molecules are larger than those found in oxygen and carbon dioxide and cannot permeate the rubber. This keeps the tyre pressure constant for a much longer period and ensures the correct amount of tyre is in contact with the road also reducing tyre wear.

Now let’s examine Temperature.

When the Temperature of a rubber tyre increases the water vapour found within the air inside the tyre reacts and causes the tyre to expand, causing the pressure to change and causing the tyre to wear more. Temperature change has little or no effect on pure nitrogen as it contains no water vapour. This keeps the tyre pressure constant when in motion and ensures the correct amount of tyre is in contact with the road, reducing tyre wear.

So tyres inflated with Nitrogen will……..

Extended tyre life

Reduced fuel consumption

Increased safety &

Higher Performance.

The Statistics.

Test have shown that the average car driver could save up to 7% on fuel bills when using Nitrogen instead of air, For example an average domestic vehicle doing around 15km per litre, covering 15,000km a year, would save up to €125.00 annually on fuel. Tests also prove that the average life of nitrogen inflated tyre is 20% – 30% longer, saving a driver doing 15,000km a year €40-€60 on replacement tyres.

So if your customer could save up to €185.00 euro a year for €6.00 fee would they pay?

No doubt about it and by you providing this service for €6.00 you will soon be inflating your profits.

To provide this service we recommend the Nitrogen Generator and inflation system.

PARTS CLEANER THAT’S SOLVENT FREE, HAS NO NASTY FUMES OR TANKS OF SOLVENTS

Posted by Willie – January 17, 2011

Finally a parts cleaner that, Cleans better, that’s Solvent free, that’s Fume free and that’s economically and envoirmently friendly.  

The SR500 is a parts cleaner that cleans your parts without solvents and respects the operator and the environment. The SR500 Parts Washer uses natural regeneration to insure an efficient and economical degreasing of parts.  

  

  

This is a better cleaner than the standard solvent cleaner and is also cheaper and more convient to maintain….  

How dose it work.
B IOLOGICAL PARTS WASHER: The Parts washer heats and regulates the liquid  which optimizes both cleaning and biodegradation. It is equipped with several cleaning possibilities (brush, spigot, soaking) and filtration systems.  

B IO LIQUIDE: Aqueous and pH neutral solution, based on specific c tensides, it is non toxic and not flammable. Solvent and safety-label free product.  

M ICRO-ORGANISMS: Concentrate of 1st class micro-organisms, which continuously clean the liquid by biodegrading the removed oils and greases. They also reduce sludge and odours.  

• Operator’s health Economical
- Solvent free - Micro-organisms continuously regenerate the    liquid
- Non toxic, safe - Lid to limit evaporation
- Not flammable - Washable and reusable stainless steel filters
- Water-based: pH neutralConditions. - Longer lifetime of the bath
   
• Efficiency • Environment
- Constant cleaning quality thanks to    bioremediation - No VOC emission (responsible for global warming)
- Efficient cleaning on any type of dirt - Sharply reduces wastes compared to solvent and saponifiers
- No greasy residue on parts - Natural biodegrading process by 1st class micro-organisms
- Parts are protected from corrosion  

AND ALSO  

• Regulation aspect
- No registration to authorities.
- No need to install a vapour extractor hood.
- A drip tray is not necessary.  

• Biodegradation
- Our natural process uses micro-organisms to transform pollutants in a source of food and energy. It also reduces sludge and unpleasant smell  

Hermetical lid Avoids Evaporation                            Washable and reusable100 micron   

Soaking higher productivity, time saving.                                      Stainless steel filter  

  

Oxygenation of the bath fastens biodegradation.                                  Adding a tablet in the liquid enables to renew  

The whole population of micro-organisms  

Every 4 to 6 weeks.  

Now lets look at how good the SR500 can safely and easily clean even the most difficult to get at parts. With the application brush and soak tank, nothing will remain on the parts.  

Before                                                                                   Before  

  

  

After                                                                                           After  

  

Users of the SR500 will find working with the Bio Soloution pleasant as it has a pleasant smell and is not harmful to the skin. The quality of the cleaning is second to none and for those hard to reach places, the brush will make this task quick and easy, thus saving time and money.  

Before                                                                               After  

  

The above housing was dated 1954 but was easily cleaned to almost new using the SR500. The speed and quality of cleaning this housing even surprised the most experienced engineers.  

Before                                                                                         After  

  

Using the soaker will clean to showroom condition with no effort at all.  

Before                                                                                      Before  

  

After                                                                                            After  

  

After cleaning using the soak tanks the parts are free of any greasy film, which means parts can immediately  be painted without the need to repeat cleaning or they can also be welded immediately.  

There is no better, safer and economically way to clean parts than the SR500 Bio Washer  

THE ALTERNATIVE TO SOLVENTS AND SAPONIFERS  

  

  

Now that we have discussed the health benefits, the cleaning efficiency and environmental benefits, let’s now look at the financial benefits and cost savings that will be made.  

  

  Solvent Parts Washer SRI Biological Washer
Degreasing Efficiency -Good when the product is new,then the quality is decreasing and the oil quantity will increase in the bath -Constant quality of degreasing
    -Aspersion and Soaking for dirty parts
    -Multi-Jets flow brush to prevent thick greases
Consumables You have to change your drum every 4.5 to 6 weeks. Important Costs -Washable and re-usable filters ( there is not comsumable filter)
    -Lid to limit liquid loses by evaporation
Bioremediation Solvent base, there is not degradation -Every month by adding a bio tab, the solution is regenerating for a repeated use and keeps the same degreasing efficiency.
Oxygenation -Solvent Base, there is not oxygenation -The bath is always oxygenated
  -Bacteries developing uncomfortable smells -No air Pump -Air pump in the machine to maintain the oxygenation. No after sales

Oil Spill Absorbent Solutions

Posted by Willie – December 6, 2010

In today’s health and safety conscious environment, Fuel spills, Including Oil, Petrol, Diesel, Brake fluid etc are a major cause for concern. Not alone for staff but also the environmental impact. There are many different Solutions to this problem but none more effective or efficient as the Pelican Pack.
Suitable for ALL FUEL SPILLS and available in 3 models to suit all workshop requirements.

1.Twisti Pack ———2.Take ‘n Go—-3.Pelican Pack

These self contained models provide all the tools required to quickly and safely absorb any fuel spill. Unlike pellets or Sawdust the absorbent used, Fibercan, instantly absorbers the spill once applied, so it can be swept up immediately. This prevents accidents as the spill is removed immediately, but it also prevents Oils being carried around the workshop due to staff movement, while the Pellets or Sawdust are left to work on the spill.

 

Apply the Fibercan- Brush thru the spill -Scoop up,floor dry

When the spill has been absorbed by the Fibercan, the used Fibercan forms lumps, and any unused Fibercan is then sifted back in to the Pelican Pack and is ready for re-use. In the sifter will be the Fibercan that has absorbed the fuel as this will have formed into lumps unable to pass thru the sifter. By being able to sift the Fibercan, this prevents waste of the Fibercan regardless of the amount applied as only used Fibercan is prevented from passing through the sifter.

There are 4 good reasons for choosing any of the range,

1. EFFICIENT – 8 Times more Efficient

  • Fibercan absorbs 8 times more than conventional absorbent materials.
  • Instantaneous absorbent
  • No more oily film: safe and dry floors.
  • Upon saturation, the absorbent powder combines to form lumps.

2. ECO – FRIENDLY. – Recyclable and reusable

  • A natural, cotton fibre based absorbent material.
  • Renewable and biodegradable.
  • Reusable. Produces 8 times less waste.
  • Captures hydrocarbons and prevents infiltration into the ground.

3. EASY TO USE – Quick and Easy

  • All in one system, storage, distribution and recovery of Fibercan.
  • All tools are provided for efficient operation.

4. MONEY SAVER – Stop waste.

  • High efficient management of consumables.
  • Consumables that are used to 100% of its capacity thanks to the sifter.
