一种经济型汽车电喷发动机改装系统

介绍一种比较经济的汽车发动机改装系统。该系统是基于微处理机的可编程电子燃油喷射与电子点火系统。点火时间与基本喷油量,使用一个标准的手持式液晶显示编程器对电控单元进行编程。空气温度、进气管压力、水温、节气门位置和转速经测量送入电控单元中,电控单元根据获得的有关参数进行计算,并送出一定频率与宽度的脉冲打开喷油器,从而精确地控制喷油量。系统适用于各种汽油发动机的改造。

A Reconstruction System for an Economic Auto Electrified Engine

A reconstruction system for an economic auto electrified engine was introduced in the paper. This system was based on the programmable EFE ( electrical fuel ejection) of a microprocessor system and an ignition system. The engine spark timing and the basic e-jection amount were controlled by the standard SDS hand-held programmer so as to program the ECU ( e-lectronic control unit ). Air temperature, windpipe pressure, water temperature, throttle position and rpm are all measured and taken into account by the ECU. Based on the relevant parameters, the ECU determines how much pulse should be sent out to open the oil ejector so as to control precisely the amount of ejection. This system is suitable for all types of gasoline-engine reconstruction.
