摘　　要：提出了高压共轨柴油机起动过程中的共轨压力建立、转速升高过程和动态烟度三方面的特点,并以排气烟度为优化目标,提出了按转速进行分阶段考察和采用正交试验方法对起动过程喷油参数进行标定和优化的方法。试验是在一台6缸6HK1高压共轨柴油机上进行的。Characteristics which involve pressure rising, rotational speed increasing and dynamic smoke emission in the startup procedure of the high pressure common rail diesel engine are brought forward in this paper. Aiming at the optimization of the exhaust smoke, the method for calibrating and optimizing fuel injection parameters is also presented,which includes the orthogonal experiment method and the division of the start process into three stages. The test is carried out on a 6cylinder common rail diesel engine.
