新型增压式柴油机共轨喷射系统的研究与开发

A Study and Development on a New Pressure-intensified Common Rail Injection System of Diesel Engines

作者研究开发的增压式共轨喷射系统,是一种在蓄压式共轨系统基础上改进而成的新型共轨系统,实验和研究结果表明,这种系统可以完全实现压力、油量和定时的独立控制,达到了产品研发的目标,满足不同的柴油机排放和性能的要求。

In this paper,the pressure-intensified common rail system is a new one that has been improved on the basis of a pressure-accumulated type of common rail system. Experiment and analytical results demonstrate that the system has realized indivedual control of injection pressure,delivery quantity and injection timing,therefore it attains the objects of production development and can meet requirements of different diesel engines in the aspects of exhause emission and economical performance.
