摘要
按9工况法规对车用电喷式汽油机进行排放测量试验,对3种有害排气污染物(CO,HC,NOx)单工况和同类工况分担率进行了分析,得出各工况对整机排放的影响程度,并提出了改善该类汽油机排放水平的重点研究工况。
The exhaust emission experiment is taken for an automotive EFI gasoline engine under 9 mode emission test cycle.Based on the calculated contributions of the single mode and same kind of test modes,each test mode emission contributions of three kinds of pollutants(CO,HCand NOx)are analyzed,the degree of the effect of the engine emission experiment results in each mode is obtained,and the key modes of this kind of gasoline engine to improve the emissions level is presented.
