摘要
利用双像高速摄影技术研究直喷式柴油机燃油束撞击雾化及燃烧过程。对轴针式喷油嘴在缸内的燃油束撞击挡块反弹雾化混合过程的火焰扩展过程进行了分析研究 ,结果表明 ,燃油束撞击反弹方向和喷油压力对油气混合气形成和燃烧过程有很大影响。
This paper reports the results of an investigation of the mixture formation and combustion process in a DI diesel engine by means of two picture high speed photography.The fuel air mixture is formed by an impinging fuel spray which impings on a head tip at the nozzle and then reflects from it to mix with air in the cylinder.Then the effect in different directions of fuel jet impingment on mixture formation and flame spread was observed and studied.At last the effect at different injection pressure was also studied.
