More and more engine firms in china have used electric control fuel injection system , as the vehicle emission regulation becomes more strict in china .The key technologies of engine electric control is the design of the hardware and software of engine control module, and the software is very important.The paper analyses the hardware of for electric control system for 465Q combined with the engine electric control theory and the practical instance of 465Q. Thinking of the experiment condition and the complex of electric control system, at present there is no ability to design electric control system . So with the sensor for 465Q and PCL1800 which can be programmed design a control system based on PC computer .The system can be satisfied for engine ignition after simulation debugging , this supplies some references for design of engine electric control later.
