電控發(fā)動機(jī)試驗(yàn)臺的設(shè)計與實(shí)驗(yàn)研究

為了教學(xué)而設(shè)計的電控發(fā)動機(jī)故障模擬試驗(yàn)臺 ，基于單片機(jī)故障設(shè)置，可以反復(fù)模
擬發(fā)動機(jī)在不同工況下各傳感器、執(zhí)行器、電控單元以及線路的各種故障。并在此試驗(yàn)臺上模擬了發(fā)動機(jī)有關(guān)傳感器和執(zhí)行器的故障，如:空氣流量傳感器等，觀察并記錄了故障現(xiàn)象，定量分析了故障對發(fā)動機(jī)性能的影響。

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.
