IMEP

基本解释

If a spark discharge is atpresent, fuel consumption and IMEP even can be improved about 20%.
另外,在HCCI運行工況範圍內,通過優化火花點火提前角,可以改善HCCI燃燒經濟性和IMEP,最高可以達到20%25。
The methanol concentration shows little effect on combustion stability (COV pmax and COV imep).
從COVpmax 和COVimep可以看出，甲醇躰積分數對發動機燃燒循環變動影響較小。
Maximum indicated mean effective pressure(IMEP)oc- curred at middle engine speed,while maximum IMEP decreased at high engine speed.
在中間轉速,HCCI實現的最高平均指示壓力最大,高轉速工況,最高平均指示壓力降低；
The cyclic variations of imep were lower than 10% in a wide range of operating conditions, which shows a stable stratification combustion.
在寬廣的轉速和負荷範圍下，平均指示壓力的循環變動不超過10%25，燃燒穩定性好。
While, the main parameters which show important influence on CO emissions are the maximum combustion temperature, pressure rising rate, IMEP, and combustion duration.
而影響CO的蓡數主要有最高燃燒溫度、最大壓力陞高率和平均指示壓力。
