摘要
研究了柴油机喷油器采用较量针阀后，由于针阀质量减轻，提高了针阀的开启速度和落座速度，减小了喷油持续角，而且燃油喷注的油滴平均直径减小，燃烧改善，从而获得明显的节油效果。
The paper deals with the fuel oil saving results of a diesel engine equiped with injectors having lighter needles. The combustion process of the engineis improved, because a lighter needle increases the lifting and seating velocities of the needle, shortenes the injection period, and reduces the mean diameter of fuel droplets.
