Design Of ECU For Gasoline Engine Fuel Ejection System

As the vehicle emission regulation becomes stricter, the vehicle electronic control technology as the key of engine control has changed more and more popular in the world. This key technology is the unique technology fitting for the require of the using of vehicle in the model society for it had made a good progress in the power, economic, emission etc.. This paper is to research and design the hardware and software of ECU based on the referrence of foreign advanced ECU technology.The key of the engine electronic control is to develop the hardware and software of ECU. The need of more accutive control for the vehicle electronics is satisfied gradually through the gradual development of the hardware and software.Combined with the request of current emission regulation and fuel qualify, we analysis the ECU technology and the real environment of 465Q engine, then designed the hardware and software of the fuel injection of the ECU with the 80C196KB of INTEL as the main CMOS chip. Drawed the hardware circuit with the PROTEL software and designed the ASM software proceeding etc..Hardware and software tests show that the improved ECU can meet the basic requires of the vehicle. At the same time, gave out the reference for the design of the best ECU in the future.
