摘要
对车用汽油机按“九工况法”进行了排放测量 ,并对各工况下的 3种有害排气污染物CO ,HC和NOX 的分担率进行了分析 ,指出了各排放测定工况对整机排放试验结果的影响程度 ,明确了改善该类汽油机排放水平的重点研究工况。
The exhaust emission data from an automotive gasoline engine is taken with 9 mode Emission Test Cycle.The test mode emission contributions of three kinds of CO,HC and NO X pollutants are analyzed.Based on the calculated contributions of the individual test mode and the same kind of test modes in the test cycle,the key modes for controlling emissions are found.
