摘　　要：在开发一种采用进油计量阀对进油计量,由凸轮轴驱动柱塞运动形成高压燃油供给蓄压器容腔的新型蓄压式喷油泵系统(NAPS)过程中,从平衡蓄压器容腔压力波动的角度,通过对传统机械喷油泵与NAPS系统的凸轮工作特点比较,得到NAPS系统凸轮设计的两个优化措施:凸轮型线优化与相位优化。基于上述优化措施本文介绍了具体的优化设计方法。During one new accumulated pump system （NAPS） designing process, on which the structure of meter valve is used for inlet fuel metering, and high pressure fuel for the accumulation volume formed by plunger moving driven by cam shaft, based on balancing the pressure wave, according to the working specifici ty comparison between traditional mechanical inline pump and NAPS, two optimized measurements are found： optimization of cam profile and phasing. The detailed optimized technique is discussed based on above meas urements.
