低压EGR系统对缸内直喷发动机性能影响的研究

doi:10.12052/gdutxb.200013

Abstract

Abstract: In order to study the effect of low-pressure exhaust gas recirculation system (Exhaust Gas Recirculation, EGR) on the fuel consumption, emissions and pumping loss of a direct-injection engine in a cylinder, a set of low-pressure EGR system control strategies is proposed based on a 2.0T direct-injection engine. The test results show that under various operating conditions, as the EGR rate increases, the specific fuel consumption decreases, the pumping loss is improved, and the carbon monoxide (CO) and nitrogen oxide (NO_x) content at the exhaust end decreases. Total Hydrocarbon (THC) content increases slightly.

Key words: exhaust gas recirculation, control strategy, specific fuel consumption, EGR rate, exhaust gas
