Ukunyuka ngokukhawuleza kwenzeka xa isantya se-injini sifikelela kwi-3000 rpm.

I-Phenomenon: Abathengi baxela ukuba iimoto zihlala zinyuka, kwaye ngalo lonke ixesha kukho ukunyuka, i-throttle (i-accelerator pedal) iphantse ibe kwindawo efanayo, kwaye kwangaxeshanye, ukusetyenziswa kwepetroli kwanda kwaye amandla ayancipha.

Uhlalutyo:

1. Inzwa ye-throttle position iphosakele.

2. I-sensor yendawo ye-crankshaft iphosakele kwaye umqondiso awuzinzanga.

I-3, ukusilela kwenkqubo yokutshisa, okukhokelela ekunqongophelweni komlilo ngengozi.

4. Ukungaphumeleli ngengozi kwe-airflowmeter

Uxilongo:

1. Biza ikhowudi yephutha, ebonisa ukuba umlinganiselo womxube ubi. Inokuthi ithathwe ukuba impazamo inxulumene ngokungenakuthintelwa nokuvuleka kwe-throttle. Ukusebenzisa i-oscilloscope ukubona i-throttle position sensor, ibonisa ukuba i-waveform yayo ibonisa ukuhla okuthambileyo kunye nokwanda kokuvuleka kwe-throttle, kwaye i-orientation yayo igudileyo kwaye i-burr-free, ebonisa ukuba i-throttle position sensor iyinto eqhelekileyo.

2. Ngenxa yesinye isici esiphosakeleyo, ukusetyenziswa kwamafutha kwanda kwaye amandla ayancipha. Imitha yokuhamba komoya kunye ne-oxygen sensor yavavanywa, kwaye izinga lokuhamba komoya laliyi-4.8g / s ngesantya esingenamsebenzi, kwaye i-voltage yesignali ye-oxygen sensor ibonise malunga ne-0.8V. Ukuqinisekisa umgangatho we-O2S, injini yaqala ukusebenza ngesantya esiphezulu emva kokukhupha ityhubhu ye-vacuum kwi-manifold intake, kwaye umqondiso we-O2S wehla ukusuka kwi-0.8V ukuya kwi-0.2V, ebonisa ukuba yinto eqhelekileyo. Nangona kunjalo, ngexesha lokusebenza kwe-idling, ukuhamba komoya kwaqhubeka kujikeleza kwi-amplitude encinci ye-4.8g / s. Emva kokukhupha iplagi yemitha yokuhamba komoya, uvavanyo lwaqalwa kwakhona, kwaye impazamo yanyamalala. Ukulungisa ingxaki emva kokutshintsha imitha yokuhamba komoya.

Isishwankathelo:

Xa i-sensor ikrokrelwa ukuba iphosakele, indlela yokukhupha iplagi ye-sensor plug (i-sensor ye-crankshaft isikhundla ayikwazi ukukhutshwa, ngaphandle koko isithuthi asikwazi ukuqala) singasetyenziselwa ukuvavanya. Xa iplagi ikhutshiwe, ulawulo lwe-ECU luya kungena kwinkqubo yokulinda kwaye ithathelwe indawo ngokugcinwa okanye ezinye iimpawu zesignali. Ukuba iphoso liyanyamalala emva kokukhupha, kuthetha ukuba impazamo inxulumene nenzwa.
