根據(jù)電磁感應原理，當通過一個線圈的磁通量增加或減少時，線圈內就會產(chǎn)生感應電動勢。飛輪齒圈每轉動一圈，通過線圈的磁通量變化58次，感應線圈就產(chǎn)生58個交變電壓信號，電壓波形如下圖所示。傳感器產(chǎn)生的低壓交變信號輸入到ECU，ECU依據(jù)信號頻率的變化計算出發(fā)動機的轉速。發(fā)動機轉速越大，磁通量變化越快，電動勢越大，信號越強;反之，信號變弱。發(fā)動機靜止時，線圈中雖有磁通，因磁通量無變化，就無電動勢產(chǎn)生，所以，傳感器也就沒有信號輸出。 </p> <p> 當感應線圈轉至信號觸發(fā)齒輪的兩個缺齒時(位于1、4缸上止點前114°)，計算機可根據(jù)此交變信號判斷出曲軸轉角基準位置(活塞壓縮上止點)，并依據(jù)此較寬的電壓信號計算出噴油時刻和點火提前角。上海發(fā)電轉速變送器</p><p
