Exhaust gas recirculation EGR. The aim is to cut back nitrogen oxide emissions. Part of the exhaust gases are fed back into the combustion course of. The engine management unit regulates the circulation of recirculated exhaust gases, whereas taking into consideration the engine pace, the quantity of aspirated air, the aspirated air temperature, amount injected and air pressure. Exhaust fuel recirculation schematic. This is positioned at the underside and rear of the engine, at the outlet of the heat exchanger for the recirculated exhaust gases.

Depending on the diploma of opening of the valve, roughly exhaust gas will cross. The control unit controls the quantity of gases recirculating at any time, by appearing on the gear motor with a hard and fast frequency and variable duty cycle signal. A sensor informs the management unit on the position of the EGR valve. It's equipped with 5 V and connected to the unit's floor. This is fastened to the engine block and situated underneath the turbocharger, it types a single unit with the EGR valve. This can be a heat exchanger that cools the exhaust gases via the engine coolant. In this fashion, nitrogen oxides emitted to the ambiance are lowered. A pneumatic valve actuates the gas bypass flap. When the coolant temperature is lower than 30 °C, the gas doesn't pass through the exchanger. When the coolant reaches 30°C, the gas is allowed to stream to the exchanger. That is positioned at the front lower part of the engine, next to the oil sump. That is an electric pump that sucks cold coolant from the primary engine radiator and pumps it to the exhaust gasoline heat exchanger. That is supplied with energy on switching on the ignition and is managed by the management unit.
