摘　　要：介绍了基于P87C552单片机控制的柴油/乙醇双燃料喷射系统的组成及工作原理。详细阐述了电控系统的硬件设计,如存储器扩展、驱动电路设计等,以及软件实现的方法,包括转速的测量方法、供油拉杆位移传感器信号的采集方法、喷射脉冲的控制方法等,并通过试验证明了该系统的可行性。Based on the micro-controlling of P87C552, the composing and operation principles of diesel / ethanol dual-fuelelectronic ejecting system are illustrated. Not only the design of hardware such as the expand of memory and the design ofdrive circuit, but also the realized methods of software, which including the measuring method of rotational speed, themethod to collect signals of fuel-feeding drag link displacement pick-up and the control method of injection pulse arediscussed in detail. The feasibility of this system is proved by tests.
