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运行工况范围内,通过优化火花点火提前角,可以改善HCCI燃烧经济性和IMEP,最高可以达到20%25。
The methanol concentration shows little effect on combustion stability (COV pmax and COV imep).
从COVpmax 和COVimep可以看出，甲醇体积分数对发动机燃烧循环变动影响较小。
Maximum indicated mean effective pressure(IMEP)oc- curred at middle engine speed,while maximum IMEP decreased at high engine speed.
在中间转速,HCCI实现的最高平均指示压力最大,高转速工况,最高平均指示压力降低；
The cyclic variations of imep were lower than 10% in a wide range of operating conditions, which shows a stable stratification combustion.
在宽广的转速和负荷范围下，平均指示压力的循环变动不超过10%25，燃烧稳定性好。
While, the main parameters which show important influence on CO emissions are the maximum combustion temperature, pressure rising rate, IMEP, and combustion duration.
而影响CO的参数主要有最高燃烧温度、最大压力升高率和平均指示压力。
