摘　　要：汽油发动机双燃料汽化器采用乙醇和汽油分开放置的燃料储存方式,避免了乙醇汽油存在的诸多弊端,在此,设计了以AT89S52单片机为核心的双燃料汽化器的微机控制系统,该控制系统实现了双燃料汽化器的按键显示、缺液检测及报警、发动机转速测量及计算、乙醇泵堵转检测及保护、乙醇量喷射控制、液压缸液压杆限位检测及保护等功能,同时,能实时采集汽车发动机的转速信号,通过预置的软件对发动机转速进行分析,精确计算出乙醇单次喷射时间和喷射频率,从而准确控制乙醇与空气、汽油的按配比混合掺烧,提高了汽油的燃烧效率,降低了油耗,减少了有害物质的排放,达到了节能减排的目的;实际应用中,该控制系统运行稳定,抗干扰性能良好,控制准确,具有一定的实际应用价值。Dual fuel carburetor gasoline engine using ethanol and gasoline separated fuel storage, avoid many drawbacks, existing in etha- nol gasoline, dual fuel carburetor design computer using AT89S52 microcontroller as the core of the control system, the control system of du- al fuel carburetor key display, detection and alarm, lack of liquid, the engine speed measurement and calculation, ethanol pump stall detec- tion and protection, the amount of ethanol injection control, hydraulic cylinder hydraulic rod limit detection and protection functions, at the same time, can real--time acquisition of automobile engine speed signal, through the preset software to analyze the engine speed, accurately calculate the single ethanol injection time and injection frequency. In order to accurately control the air, ethanol and gasoline according to the ratio of mixed burning, improving the combustion efficiency of gasoline, reducing fuel consumption, reduce The emission of harmful sub stances to achieve the purpose of energy saving and emission reduction. In practical application, the control system runs stably and has good anti--jamming performance and accurate control.
