Lean burn mixture combustion of gasoline engine is an effective approach for reducing emissions and fuel consumption.
汽油机燃烧稀混合气是降低有害尾气排放、燃油消耗率的有效途径。
This strategy furnishes an extremely lean overall mixture for idling and part-throttle operation, with commensurate reductions in fuel consumption.
这个战略装备虚度光阴和部分节流孔操作的一个极端精瘦的整体混合物，与对燃料消费的比照减少。
A lean mixture combustion system is presented in this paper. And the test effect of fuel injection time, fuel adjustment, miximum load speed and emission characteristics are analysed.
介绍了一种汽油机的快速稀燃系统，并对该系统的喷油时刻，燃油调整特性，外特性及排气性能等进行了试验分析。
Compared with stoichiometric mixture operation, fuel economy and emissions are remarkably influenced by injection timing when lean mixture is applied.
在发动机燃用稀薄混合气时，喷油定时对排放和经济性的影响较为明显。
When the CH4-air mixture approaches the lean fuel state, the flame speed accordingly decreases, the flame cone rising and retreating downstream to the area with lower flow speed.
从化学计量向贫燃料状态靠近时，预混火焰强度减弱，火焰传播速度减小，锥形火焰面逐渐增高，退到流速较低的下游区域；
