ABSTRACT

To adapt to the professional technical personnel in the engine disassembling, engine control principle and fault diagnosis of the aspects of design, research and training of engine comprehensive test experimental teaching platform. Experimental platform can be installed 1ZR - FE model test, chest electronic-controlled engine with various simulation hige switch control panel, can simulate various system fault, suitable for teaching work.

This paper mainly introduces the design of the experimental electronic-controlled engine purpose, significance and development present situation, the composition and working principle, and on the basis of experimental design electronic related content. Including experimental platform design and test the circuit design and decorate ark, engine disassembling and fault setting and detection, etc.

Through the design of experiments, deep understanding and mastering of electronic-controlled engine components and work principle, mechanical CAD design and related knowledge of mechanical drawing, but also involves engine disassembling and engine fault detection, working out and set, detection of artificial of practical application, and finally a design in mechanical, electrical and integration of the product.

Key words：Electronic fuel injection engine；Experimental Plat；Disassemblie；

Detection；Fault detection
