IMEP

基本解釋

If a spark discharge is atpresent, fuel consumption and IMEP even can be improved about 20%.
另外,在HCCI運行工況范圍內(nèi),通過優(yōu)化火花點火提前角,可以改善HCCI燃燒經(jīng)濟性和IMEP,最高可以達(dá)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，甲醇體積分?jǐn)?shù)對發(fā)動機燃燒循環(huán)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(zhuǎn)速,HCCI實現(xiàn)的最高平均指示壓力最大,高轉(zhuǎn)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(zhuǎn)速和負(fù)荷范圍下，平均指示壓力的循環(huán)變動不超過10%25，燃燒穩(wěn)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的參數(shù)主要有最高燃燒溫度、最大壓力升高率和平均指示壓力。
