Electric control engine test-bed design and experimental study （1 Guangdong Industry and trade Professional Technology College， Zhao Wen-long 2 Teachers Campus,Guangzhou Technology Teachers College, Li Li-bin 3 South China Agricultural University，Zhao Zuo-xi） Abstract：In order to teaching designed to electronically controlled engine fault
simulation test bed, based on single chip fault settings, can be repeated simulation
engine under different conditions in various sensors, actuators, electronic control
units, as well as all kinds of fault lines. And in this test bed to simulate the
engine sensors and actuators-related failures, such as: air flow sensors to observe
and record the fault phenomena, quantitative analysis of the failures to the engine
performance.
