本文在92单缸汽油机上观察了采用紧凑型和浴盆形两种燃烧室,气缸压力在相位和数值上的循环变动;并用数理统计方法定量地比较了两种燃烧室中混合比、点火提前角、转速对气缸压力循环变动的影响。
In this paper, we observed the cyclical variation of the cylinder pressure in phase and numerical values on a 92-cylinder gasoline engine using a compact and bimodal combustion chamber. The mathematical and statistical methods were used to quantitatively compare the mixing ratio, ignition advance angle , The speed of the cylinder pressure cycle changes.
