摘　　要：介绍了一种自行开发的柴油机电控掺烧乙醇的多点喷射系统。该系统利用16位高性能单片机C167CS和传感器系统,通过采集传感器信号进行数据分析处理,优化控制输出以及显示的自动化和数字化,以实现乙醇的实时、高速的定掺比掺烧。其中详细阐述了电控系统的硬件设计如喷醇的驱动电路和软件实现编程的思路和方法,比如转速采集模块编程。并通过试验证明了该系统的可行性。This paper introduces a self-developed electronically controlled multi-point diesel/ethanol injection system. By using high performance 16bit MCU C167CS and sensors, signals were captured and data were processed, control outputs were optimized accordingly, thus realize the real-time fixed blending ratio of ethanol. Also this paper gives the detailed information of hardware and software designs, such as the driven circuit of ethanol injector and speed capture software module. System feasibility was proved by experimental results.
