Electrical exhaust gas recirculation电子废气再循环

好人

Pressure diagnosis
While exhaust gas is admitted into the intake manifold, the intake manifold pressure sender must register a rise in pressure (less partial pressure). The engine control unit compares the pressure rise in the intake manifold with the supplied exhaust gas quantity and can thus determine whether the exhaust gas recirculation (EGR) system is functioning properly. This diagnosis is only carried out in overrun mode, because injection is deactivated as a disturbing influence for measurement and the intake capacity of the engine is very high.

部分负荷时EGR阀将部分废气重新引入气缸，主要目的降低气缸燃烧温度，降低NOx排放
