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.
Based on the understanding of structure, principle, measure and maintenance of electronic fuel injection system and learning theory, I take full advantage of the multimedia technique to exploit the multimedia CAI system for principle and maintenance of electronic fuel injection system. By the study of this courseware developed , learners can understand and master the structure, principle, measure and maintenance of electronic fuel injection system.
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.
In this paper, a single-chip microprocessor controlled MPI system is described. The MPI system not only has the ability to control fuel supply accurately for most engine operating modes so as to improve fuel economy, exhaust emission and engine performance considerably, but also can perform selfdiagnosis. The principle, construction, software and hardware development of the system and the way of engine mapping are discussed here in detail and test results are also provided.
The construction and working principle of ignition and fuel injection subsystemsand electrical control unit of an ignition and fuel injection combined electrical control fuel injectionsystem are presented,and main advantages of the system are explained. Function of ignition controland proportioning condition of air fuel compound of the system under the engine operation rnode ofcold starting,warm up operating,accellerating,full load and idling are expounded.
General situation of development of electronically controlled fuel injection systemof engine and its classification are described,and construction and working principle of each compo-nent in its induction system,fuel system and electronic control system are recommended. 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 main...
