摘　　要：本研究应用计算机控制技术和CPLD大规模可编程逻辑阵列数字信号处理技术研制出一种甲醇/汽油灵活燃料发动机智能控制装置,实现了发动机任意比例甲醇汽油燃料的智能识别和喷射量的精确控制。实际装车结果表明,该装置工作性能稳定,控制精度高,通用性好,适用于各种车型的甲醇化改造。When a car is converted into gasoline, methanol or any proportion of gasoline and methanol blending one, a new kind of intellectual methanol/gasoline flexible fuel control device is developed by computer control technologies and CPLD logic circuit digital signal processing. The controller can satisfy the engine characteristic, realize the fuels intellectual identification and precision control of injection quantity. The controllers were fixed on in-use cars and a lot of experiments were made. The results show that the device has characters of working stable, high control accuracy and best commonality, It can be used in refitting kinds of in-use cars into burning gasoline/methanol ones.
