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。
Study on the Impingement and Combustion Process of Direct Injection Diesel Engine Bump with Dual - image High - speed Photographic Technology. The flame expansion process of the atomization mixing process of the fuel injection beam striking block in the axial injection nozzle was analyzed and studied. The results show that the direction and injection pressure of the fuel beam impacting on the formation and combustion process of the mixture have a great impact.
