lean mixture

基本解释

The engine will not run well with a lean mixture and may stumble or stall.
使用稀薄的混合气，发动机将不能很好地运转，并会出现加速后坐现象或失速停车现象。
In order to cater to the needs of lean mixture combustion, the energy for ignition should be increased and the discharging time should be lengthened.
为适应稀混合气燃烧，应加大点火能量、延长火花放电时间，所以点火系统采用电感放电模式较好。
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。
