Automotive Engine Idle Electronic System Design and Test

Guest Editor Huier Liu (North China University of Water Resources and Electric Power, China)

The idling of engine has natural and random fluctuations of rotation speed caused by variations in engine intake, volatility of exhaust and randomness of combustion, which are all present during the idling state. Changing ignition advance angle can rapidly control the rotation speed accurately, the reason for which is that ignition advance can influence the torque of engines. The research reported here aims to design fuzzy algorithms to control the idling speed of automotive engines. The output of fuzzy interference is duty cycle ratio and ignition advance ratio of air bypass valve control signal. The engine bench test results indicate that the method can shorten warm-up time and stabilize speed fluctuation during idling, and the control effect of idling stability is equivalent to the original engine.
