indlela yokufaka isicelo

1. Ukuba i-injini ye-injini ye-fuel elawulwa nge-elektroniki ixhotywe nge-oxygen sensor yokukhupha i-oxygen iyasilela ekusebenzeni, njengesantya esingazinzanga, ukukhawuleza okubuthathaka, ukunyuka kokusetyenziswa kwepetroli kunye nokukhupha igesi eninzi, kwaye akukho siphoso kunikezelo lwamafutha kunye nesixhobo sokutshisa. kusenokwenzeka ukuba kukho into engalunganga ngesivamvo seoksijini kunye neesekethe ezinxulumeneyo.

I-2.Inkqubo yokulawula i-elektroniki yeenjini ezininzi inomsebenzi wokuzijonga. Xa i-sensor ye-oksijeni okanye iinxalenye ezihambelanayo zingaphumeleli, ikhomputha iya kubhala ngokuzenzekelayo umxholo wephutha, kwaye abasebenzi bokulondoloza banokufumanisa ingxaki kuphela ngokufunda ikhowudi yephutha kunye ne-decoder ekhethekileyo. Kodwa kuthekani ukuba akukho sixhobo sikhethekileyo? Nazi iindlela ezininzi zokujonga ngokukhawuleza umgangatho we-oxygen sensor.

3.Ukuba kukrokrelwa ukuba ukungaphumeleli okufana nesantya sokungazinzi okanye ukukhawuleza okungahambi kakuhle kubangelwa inzwa ye-oksijeni, khupha nje i-connector ye-oxygen sensor xa ugqithisa. Ukuba ukusilela kwe-injini kuyanyamalala, oko kuthetha ukuba i-oxygen sensor yonakalisiwe kwaye kufuneka itshintshwe. Ukuba ukusilela kwe-injini kuhlala, fumana isizathu kwezinye iindawo.

I-4.Ukusebenzisa i-voltmeter ephezulu ye-impedance inokukhangela umgangatho we-oxygen sensor. Xhuma i-voltmeter ngokuhambelana ekupheleni kwesiphumo senzwa ye-oxygen. Kwiimeko eziqhelekileyo, i-voltage kufuneka itshintshe phakathi kwe-0-1V, kwaye ixabiso eliphakathi li malunga ne-500mV. Ukuba i-voltage ephumayo ihlala ingatshintshi ixesha elide, ibonisa ukuba inzwa ye-oxygen yonakalisiwe.

I-5.Enyanisweni, i-sensor ye-oxygen yinto ehlala ixesha elide, kwaye ingasetyenziselwa iminyaka eyi-3 okanye ngaphezulu nje ngokuba umgangatho wepetroli udlula umgangatho. Umonakalo ongaqhelekanga wenzwa ye-oxygen ubangelwa ubukhulu becala ngumxholo okhokelayo ogqithisileyo kwifutha. Abaqhubi abaqhuba iimoto ezixhotyiswe ngezixhobo zendlela-ntathu kufuneka banikele ingqalelo koku.
