The camshaft adjustment valve (also known as an oil control valve) is an integral part of the variable valve timing (VVT) system in modern engines. Each manufacturer has different technology and terminology for the system, some of the most recognisable names include VVT, VVTi, VTEC and VTi (For a full list please see Table 1). …
Exhaust Gas Temperature (EGT) Sensors are now used on over 30% of all new vehicles including most major manufacturers such as Volkswagen Automotive Group, Ford, Fiat, BMW, Renault and Mercedes to name just a few. Although a relatively recent introduction, the aftermarket is seeing an increasing demand for replacements. In this bulletin we’ll take a…
So what are Fuel Vaporizers? The Fuel Vaporizer is a relatively new component designed to improve the DPF regeneration process and further reduce harmful emissions. DPF regeneration requires extremely high temperatures for soot to be removed from the DPF by combustion. When normal driving conditions do not allow for this temperature to be reached in…
Lambda sensors were first fitted to cars in 1977 to improve the efficiency of combustion engines and help to reduce harmful exhaust emissions such as carbon monoxide. Lambda sensors operate by measuring the amount of oxygen in the exhaust. An efficient engine requires a specific amount of air and fuel in it’s cylinders at combustion….
The Exhaust Gas Recirculation Valve Do you notice a higher than average EGR valve return rate? Do your customers report symptoms reoccurring prematurely after replacement?In this Technical bulletin we look at how the EGR valve works, the causes and symptoms of failure and how to ensure longevity of the replacement valve. What is it for? Fundamentally the EGR valve reduces harmful nitrogen…
After replacing engine management components, many vehicles will require a reset of the parameters to tell the ECU that a new part has been fitted. Without this, the ECU will believe that the engine is still running with faulty sensors and will default back to data already received before the replacement. This causes the vehicle to run poorly, normally with the…
What are Cam and Crankshaft Sensors? The Camshaft Sensor monitors the positions of the camshaft to allow for correct ignition timing. The Crankshaft Sensor detects the position of the crankshaft allowing the ECU to calculate its position in relation to the pistons in the engine. There are two main types of sensor: Inductive Sensor Inductive…
