CA6102型车用汽油机燃烧室的改进

DEVELOPMENT OF A NEW COMBUSTION CHAMBER FOR CA6102 VEHICLE GASOLINE ENGINE

在单缸试验机上对ＣＡ６１０２型汽油机燃烧室的改进试验结果表明：该燃烧室在燃用ＭＯＮ７０汽油时具有较强的抗爆能力和较高的燃烧速率，利于采用较高压缩比和燃用稀薄混合气，改善了发动机的燃油经济性和动力性，且生产时无须更改原有加工设备，便于推广应用．

This paper describes the improvement of the combustion chamber of CA6102vehicle engine. Tests on a single-cylinder test engine show that, when MON70 gasoline is burnt,the new combustion chamber gives a higher combustion rate and better anti-knock ability. Thusa higher compression ratio and leaner mixture can be used, resulting in better fuel economy andhigher power output. Since no change in the manufacturing equipment is needed, the improvedcombustion chamber can be easily utilized.
