This dissertation expounds the application prospects of the electronic controlled gasoline injection engine, introduces the automobile fault diagnosis technique and the current fault simulation method, analyzes the status and the problems of the automobile repairing industry, introduces the structure and the working principles of the main sensors and actuators, and the fault diagnosis and test methods of the electronic controlled gasoline injection engine.
Vacuum degree of air intake has direct influence over sealing performance of cylinder,blockage of exhaust system,air fuel ratio(A/F),ingition performance and valve timing. Therefore,its an efficient method to detect and analyze the fault of direc gasoline injection engine with vacuum meter.
In the meantime, it can conveniently detect and collect the information as much as possible, and repeatedly simulate various faults of the sensors, the actuators, the electronic unit and the circuitry under different working conditions.
This dissertation formulates the development and actuality of the electronic controlled gasoline engine, introduces the approach and method of diagnosis this kind of engine, and some advert proceeding.
The Air-fuel ratio control system is the important composing part to pledge its fuel economy, low emission and good driveability. The principle and control process are very important to run engine normally.
Toyota has already introduced lean burn engines, a direct injection gasoline engine and other fuel efficient engines into the market.

Vacuum degree of air intake has direct influence over sealing performance of cylinder,blockage of exhaust system,air fuel ratio(A/F),ingition performance and valve timing.Therefore,its an efficient method to detect and analyze the fault of direc gasoline injection engine with vacuum meter.The authors expound principles of detecting fault and specific methods with vacuum meter in detail with some concrete examples.
How to get rid of a puzzling question of car trouble accurately based on correctly analyzing the cause is presented in this article, taking the Honda Accord LX car as a random example. The rouble in the example is that automatic transmission shifting is retarded from the correct engine speed of 2 000 r. p. m. until it reaches up to 4 000 r. p. m. The engine has an electronically cortrolled gasoline injecting system and transmission is of 7 shifts automatic.
