Engine EGR
What is an EGR? EGR stands for exhaust gas re-circulation, it is an effective method to control Nitrogen Oxides (NOx) emissions produced by petrol and diesel engines. The EGR is often located on the inlet manifold of the engine, however sometimes it can be located...
What causes carbon build-up in the EGR system? Your car’s Exhaust Gas Recirculation (EGR) system recirculates a portion of your engine’s exhaust gases back into the engine’s combustion chamber. This results in reduced exhaust emissions as well as...
What does the EGR Valve Position sensor do? Exhaust Gas Recirculation (or EGR) systems were introduced to cars as a means of reducing emissions. As their name suggests, they recirculate partially burnt exhaust gases back into the engine where they are re-burnt to...
What is the EGR Control Solenoid? The EGR control solenoid controls the flow of exhaust gases to the intake manifold. When the solenoid is activated, exhaust gases are sent back into the engine cylinders for re-combustion. The EGR control solenoid is controlled by...
What is the Engine EGR pressure feedback sensor? The EGR pressure feedback sensor is a vital component of the EGR (exhaust gas recirculation) system, which helps to reduce harmful emissions by recirculating a portion of the exhaust gases back into the engine’s...
What is the EGR temperature sensor? Your car’s exhaust gas recirculation (EGR) system is an important emission control system that allows gases to be sent back into your engine via the intake manifold. The gases are then re-burnt, allowing for a decrease in...
