進氣溫度傳感器簡介

進氣(qi)(qi)溫(wen)(wen)度(du)(du)傳感器是(shi)一個負溫(wen)(wen)度(du)(du)系數熱敏(min)電(dian)(dian)(dian)阻(zu)，當溫(wen)(wen)度(du)(du)升高(gao)時，電(dian)(dian)(dian)阻(zu)阻(zu)值減(jian)小，當溫(wen)(wen)度(du)(du)降低時，電(dian)(dian)(dian)阻(zu)阻(zu)值增(zeng)大(da)，隨著電(dian)(dian)(dian)路中電(dian)(dian)(dian)阻(zu)的變化，導(dao)致電(dian)(dian)(dian)壓的變化，從而(er)產(chan)生(sheng)不同的電(dian)(dian)(dian)壓信(xin)(xin)號(hao)(hao)，完成控制系統的自動操作(zuo)。在(zai)(zai)冷(leng)車(che)時，進氣(qi)(qi)溫(wen)(wen)度(du)(du)傳感器的信(xin)(xin)號(hao)(hao)與(yu)發動機水溫(wen)(wen)傳感器信(xin)(xin)號(hao)(hao)基(ji)本相同，在(zai)(zai)熱車(che)時，其信(xin)(xin)號(hao)(hao)電(dian)(dian)(dian)壓大(da)約是(shi)水溫(wen)(wen)傳感器的2~3倍。

進氣溫度傳感器的作用

進(jin)氣(qi)(qi)溫(wen)度(du)傳(chuan)感器(qi)的(de)作用是檢(jian)測發動(dong)機的(de)進(jin)氣(qi)(qi)溫(wen)度(du)，送(song)給ECU作為修(xiu)正噴油(you)量(liang)的(de)參考。該(gai)傳(chuan)感器(qi)在電控燃油(you)噴射系統中測量(liang)進(jin)氣(qi)(qi)溫(wen)度(du)，并(bing)輸入到ECU，用以(yi)修(xiu)正體積型(xing)空氣(qi)(qi)流量(liang)傳(chuan)感器(qi)由(you)于(yu)大氣(qi)(qi)溫(wen)度(du)變化帶來的(de)進(jin)氣(qi)(qi)質(zhi)量(liang)檢(jian)測的(de)誤差。
