摘要
发动机电子控制节气门系统包括电控单元、直流电机、减速齿轮、驱动电路等。与传统的节气门控制方法不同,电子节气门系统中节气门在任何工况下都直接由电机驱动。电控单元可根据车辆信息和发动机工况的变化而随时配制一个理想的混合气。这种理想的混合气,可同时满足发动机的动力性、经济性要求,并减少有害物物的排放,具有良好的怠速、加速、减速等工况的过渡性能。开发一套基于虚拟仪器的电子节气门数据测试系统,对国外先进发动机的电子节气门控制系统控制策略进行研究,对科研和教学都有重要的意义。
Electronic throttle control system of the engine consists of electronic control unit, direct-current motor, speed reducing gear and drive circuit and so on. The throttle in the electronic throttle system can be driven directly by motor in any case compare with the traditional throttle control in different way. The ECU can provide an ideal air-fuel ratio at any time according to vehicle information and change of engine operating condition. The ideal mixture can meet the engine power, economy and reduce harmful emission, with good transition performance for idle, acceleration and deceleration. A set of data test system for electronic throttle has been developed and study the control strategy of it, which is significant both teaching and research.
