为了教学而设计的电控发动机故障模拟试验台 ,基于单片机故障设置,可以反复模拟发动机在不同工况下各传感器、执行器、电控单元以及线路的各种故障。并在此试验台上模拟了发动机有关传感器和执行器的故障,如:空气流量传感器等,观察并记录了故障现象,定量分析了故障对发动机性能的影响。关键词 :电控发动机 ;模拟试验 ;实验台 ;实验分析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 faultsimulation test bed, based on single chip fault settings, can be repeated simulationengine under different conditions in various sensors, actuators, electronic controlunits, as well as all kinds of fault lines. And in this test bed to simulate theengine sensors and actuators-related failures, such as: air flow sensors to observeand record the fault phenomena, quantitative analysis of the failures to the engineperformance.Key words: Electronic—controlled engine;Simulation test heneh;Experimental rig;Tests and analyses
