废气排放极限值的不断严格,日益短缺的资源及保护环境的要求以及对现代轿车用直喷式柴油机舒适要求的进一步提高,对新型喷油系统的开发提出了巨大的挑战。针时发动机厂家的各种不同要求,Bosch公司开发了一系列电磁阀控制的高压喷油系统。本文介绍VP44型径向柱塞泵、VP37型轴向柱塞式分配泵、泵喷嘴系统和共轨式喷油系统及其各自的优点。 The increasingly stringent emission limits, increasingly scarce resources and the need to protect the environment, as well as the further enhancement of the comfort requirements for direct injection diesel engines for modern cars pose a huge challenge to the development of new fuel injection systems. Bosch has developed a series of solenoid valve-controlled high-pressure fuel injection systems for various requirements of the engine manufacturer. This article describes the VP44 radial piston pump, VP37 axial piston distributor pump, pump nozzle system and common rail injection system and their respective advantages.
