Exhaust gas recirculation (EGR) is a nitrogen oxide
emissions reduction technique used in petrol and
diesel engines. The EGR valve works by recirculating
a proportion of the engines exhaust gas back in to
the engine cylinders, this vastly increases efficiency
whilst the engine is cold and, results in a cleaner,
more complete burn of fuel.
The Exhaust Gas Recirculation (EGR) Cooler uses
the engines coolant to help reduce exhaust gas
temperatures prior to recirculating them through the
engines intake system. The EGR Cooler prevents
damage to expensive components downstream
in the exhaust system, like the turbocharger, and
prevents the build-up of pollutants due to excessive
temperatures.
The Exhaust Gas Temperature Sensor (EGTS) is located in either the front of the
Diesel Catalyst and depending on vehicle manufacturer it can also be located
in front of the Diesel Particulate Filter (DPF) this sensor detects exhaust gas
temperature and converts this into a voltage signal. This information is then
sent back to the engine ECU with the voltage signal in order to control engine
conditions to effectively reduce emission. Higher engine temperatures can
cause premature engine wear and in some cases engine failure.
