摘　　要：介绍了MPC555在柴油转子发动机燃油喷射系统中的应用。主要介绍了整个电控系统的核心ECU的设计原理和方法及外围电路和控制策略及各种传感器的A/D转换、喷油器控制、高压泵控制喷油压力控制和CAN总线接口电路。系统具有集成度高,可靠性好的特点,初步试验验证所控制的转子机单缸转速和功率分别达到4 400r/min和25kW。This paper dealt with the application of MPC555 to a fuel injection system for a diesel rotary piston engine. And the hardware design principle and method were introduced. This system took the MPC555 micro controller as its core and was also provided with some correlative circuits consisting of a few kinds of sensors, the A/D conversion, nozzle control, high pressure bump control, injection pressure control and the CAN bus interface circuit etc to realize the exact control of the engine. The electronic control injection system based on the MPC555 had the merits of high density of integration and high reliability, and could control the speed of engine up to 4400 r/min and the power of the engine up to 25 kW per cylinder respectively.
