This paper introduces the character of structure, working principles of the electronic fuel injection system used on YBL6980Q11b bus and how to eliminate the common troubles
This paper mainly studies design and developing technique of the multimedia CAI system for principle and maintenance of electronic fuel injection system.
Five kindsof inspection methods for electronically controlled fuel injection failures are put forward,and theelectronic control fuel injection system of model 2JZ-GE engine on the Toyota Crown 3. 0 car istaken as object to recommend the maintenance method and its procedure by means of technologicalparameter measuring process with universal meter.
The test results showed that a two stroke engine with electronically controlled fuel injection system had better fuel consumption and exhaust emission performances.
General speaking, the measurement on the fuel consumption is defined through the experiment of engine's fuel consumption, but the wide spread of electronic gasoline injection engine (EGI) has brought about a new problem to the measurement, i.e. traditional methods such as volume measurement and weight measurement cannot work when EGI engine returns oil by a great amount and supplies oil in a high pressure and when oil pipes have beared different pressure and temperatures.
The effects of spark timing, air-fuel ratio, engine rotative speed and engine load on engine exhaust emissions within the electronic gasoline injection system of modern vehicle engines have been investigated.
