清潔吸污車電(dian)噴發(fa)念頭點(dian)(dian)(dian)火(huo)體系的結(jie)構跟(gen)(gen)工作原理比傳(chuan)統(tong)的觸點(dian)(dian)(dian)式點(dian)(dian)(dian)火(huo)體系或(huo)天觸點(dian)(dian)(dian)電(dian)子點(dian)(dian)(dian)火(huo)體系要龐(pang)雜的多(duo)，其(qi)不能點(dian)(dian)(dian)火(huo)故障(zhang)(zhang)起(qi)因(yin)的范疇也比較廣。為了僅于查找跟(gen)(gen)剖析(xi)故障(zhang)(zhang)起(qi)因(yin)，可將其(qi)分為高壓電(dian)路故障(zhang)(zhang)跟(gen)(gen)低壓電(dian)路故障(zhang)(zhang)兩(liang)類。

1.高壓(ya)電路故障

清潔吸污(wu)車電(dian)噴(pen)發念頭(tou)點(dian)火(huo)體(ti)系的高壓電(dian)路(lu)跟傳統點(dian)火(huo)體(ti)系的高壓電(dian)路(lu)基本(ben)雷同，重要由點(dian)火(huo)線圈、分電(dian)器、高壓線、火(huo)花塞等(deng)組成，其故障起因跟傳統點(dian)火(huo)體(ti)系類似。

其(qi)起因有：

(1)高壓(ya)(ya)線圈次級(ji)繞組斷路或短路，使之無奈在點火(huo)把持器的把持下將伯壓(ya)(ya)電源轉(zhuan)換成高壓(ya)(ya);

 (2)分電器(qi)的分火頭或分電器(qi)蓋漏電，使(shi)點火線(xian)圈產生的高壓(ya)電在送至各缸火花塞之前(qian)中(zhong)途搭鐵;

(3)清潔吸污(wu)車(che)高(gao)壓(ya)線斷路，使點火線圈(quan)產生的(de)高(gao)壓(ya)電(dian)無奈達到火花塞。

2.低壓電路(lu)故障(zhang)

清潔吸污(wu)車(che)電(dian)噴(pen)(pen)發(fa)(fa)念(nian)頭點(dian)(dian)火(huo)(huo)(huo)體(ti)系的(de)龐雜之處重要在低(di)壓電(dian)路(lu)(lu)，它是發(fa)(fa)念(nian)頭電(dian)控體(ti)系的(de)一個組成局部。要使點(dian)(dian)火(huo)(huo)(huo)體(ti)系的(de)低(di)壓電(dian)路(lu)(lu)能(neng)畸(ji)(ji)形(xing)工作，除了點(dian)(dian)火(huo)(huo)(huo)線(xian)圈及(ji)(ji)點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持器(qi)(qi)(qi)的(de)電(dian)源(yuan)電(dian)路(lu)(lu)必須畸(ji)(ji)形(xing)外，還請求發(fa)(fa)念(nian)頭把(ba)(ba)持體(ti)系的(de)電(dian)源(yuan)電(dian)路(lu)(lu)也能(neng)畸(ji)(ji)形(xing)供電(dian)，且(qie)把(ba)(ba)持體(ti)系中有關點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持的(de)局部能(neng)畸(ji)(ji)形(xing)工作。因(yin)為發(fa)(fa)念(nian)頭電(dian)控體(ti)系存在一定(ding)的(de)生(sheng)效維護功能(neng)，因(yin)此(ci)除了曲軸(zhou)(zhou)位(wei)置(zhi)(zhi)傳感(gan)器(qi)(qi)(qi)之外，其(qi)(qi)余的(de)傳感(gan)器(qi)(qi)(qi)故(gu)障(zhang)均(jun)不會導致不點(dian)(dian)火(huo)(huo)(huo)故(gu)障(zhang)。只有曲軸(zhou)(zhou)位(wei)置(zhi)(zhi)傳感(gan)器(qi)(qi)(qi)能(neng)畸(ji)(ji)形(xing)產生(sheng)信號并送(song)入發(fa)(fa)念(nian)頭電(dian)腦(nao)，發(fa)(fa)念(nian)頭電(dian)腦(nao)能(neng)發(fa)(fa)出(chu)點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持信號并送(song)入點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持器(qi)(qi)(qi)，點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持器(qi)(qi)(qi)就應(ying)能(neng)把(ba)(ba)持點(dian)(dian)火(huo)(huo)(huo)線(xian)圈產生(sheng)高壓電(dian)。因(yin)此(ci)，清潔吸污(wu)車(che)電(dian)噴(pen)(pen)發(fa)(fa)念(nian)頭點(dian)(dian)火(huo)(huo)(huo)體(ti)系低(di)壓電(dian)路(lu)(lu)故(gu)障(zhang)的(de)范疇重要在曲軸(zhou)(zhou)位(wei)置(zhi)(zhi)傳感(gan)器(qi)(qi)(qi)及(ji)(ji)其(qi)(qi)線(xian)路(lu)(lu)、發(fa)(fa)念(nian)頭電(dian)腦(nao)及(ji)(ji)其(qi)(qi)線(xian)路(lu)(lu)、點(dian)(dian)火(huo)(huo)(huo)把(ba)(ba)持器(qi)(qi)(qi)及(ji)(ji)其(qi)(qi)線(xian)路(lu)(lu)3個方面。
