摘要

为研究低压废气再循环系统(Exhaust Gas Recirculation

EGR)对缸内直喷发动机油耗、排放和泵气损失的影响

基于某2.0T缸内直喷发动机

提出了一套低压EGR系统控制策略。试验结果表明

在各个工况下

随着EGR率的升高

比油耗出现降低的情况

泵气损失得到良好改善

排气端的一氧化碳(CO)和氮氧化物(NO

)含量降低

总碳氢化合物(Total Hydrocarbons，THC)含量略有升高。

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

) content at the exhaust end decreases. Total Hydrocarbon (THC) content increases slightly.
