Izimpawu ze-Actuator Enephutha noma Engalungile

Izimpawu ezijwayelekile zifaka i-throttle oscillation, ukonga kahle kukaphethiloli, nokuvalwa kwenjini okuvamile.

Esikhathini esidlule, lapho umshayeli eshayela ekhuphuka enesisindo esengeziwe ngemuva kwemoto noma emane evula i-air conditioner, unyawo lwakhe lwangakwesokudla lwaluwukuphela kwendlela yokunyusa isivinini. Njengoba ubuchwepheshe buye bathuthuka futhi izimoto eziningi sezishintshile zisuka kukhebula le-throttle manual zaya kuzilawuli ze-electronic throttle, kwenziwe ukuthuthukiswa okuningi ohlelweni lukaphethiloli ukuze kuthuthukiswe ukusebenza kahle kwenjini nokunethezeka komshayeli. Enye ingxenye enjalo i-throttle actuator. Nakuba kuyi-actuator kagesi, ingahluleka, kudinge ukuthi indawo yayo ishintshwe umakhenikha oqinisekisiwe.

Iyini i-throttle actuator?

I-throttle actuator iyisakhi sokulawula i-throttle esiza ukulawula ukulawulwa kwe-throttle ezimeni lapho i-throttle eyengeziwe idingeka ngokuzumayo noma lapho ukuncishiswa kwe-throttle kungazelelwe kuyadingeka. Lapho i-accelerator pedal ikhishwa kungazelelwe, i-activator throttle isebenza ukunciphisa kancane kancane isivinini senjini, futhi ingawi ngokuzumayo. I-throttle actuator iphinde isize ukugcina izindawo ezithize zokudonsa umoya lapho kufakwa umthwalo owengeziwe noma i-voltage enjinini, njengalapho kusetshenziswa izisetshenziswa zezimoto ezihlukahlukene njengesipholisa-moya, ukuvula isistimu yokukhipha amandla elolini elinesistimu yokushisela engaphakathi, noma noma ngabe usebenzisa umsebenzi wokuphakamisa iloli. .

I-throttle actuator ingalawulwa nge-elekthronikhi noma nge-vacuum. Kumodi ye-vacuum, i-actuator ivula i-throttle kancane ukuze ikhulise ukugeleza komoya/kaphethiloli. I-idle control actuator ilawulwa i-idle control actuator solenoid. Le solenoid ilawulwa imojuli yokulawula. Uma le solenoid ivaliwe, akukho vacuum esetshenziswa ku-actuator yokulawula i-idle, ukuyivumela ukuthi ivule kancane i-throttle ukuze inyuse isivinini sokungenzi lutho. Ukuze kwehliswe isivinini sokungenzi lutho, le solenoid iyasebenza, kusetshenziswa i-vacuum ku-actuator yokulawula ukungenzi lutho, okuvumela i-throttle ukuthi ivaleke ngokugcwele.

Njengezingxenye eziningi zemishini ezitholakala ezimotweni kulezi zinsuku, i-throttle actuator yakhelwe ukuhlala impilo yemoto. Kodwa-ke, ingaphansi kokuguga futhi ingahluleka, ihluleke noma iphuke. Uma lokhu kwenzeka, umshayeli uzokwazi ukubona izimpawu ezimbalwa ezimxwayisa ngenkinga engase ibe khona nge-throttle actuator nokuthi kungase kudingeke ukuthi ishintshwe.

1. Ukudlidliza kwe-throttle

Isikhathi esiningi, injini iphendula umshayeli ecindezela i-pedal yegesi ngaphandle kokungabaza noma ukungabaza. Nokho, lapho i-throttle actuator ilimele, ingathumela ukufundwa okungalungile ku-ECM futhi ibangele uphethiloli omningi kunomoya ukuthi ungene enjinini. Kulokhu, isimo esicebile sidalwa ngaphakathi kwegumbi elivuthayo, elingabangela injini ukubambezela ukuthungela ingxube ye-air-fuel. I-kicker actuator ivamise ukuba ingxenye yesistimu yomjovo kaphethiloli we-elekthronikhi ebonisa lolu phawu lapho inzwa yonakele futhi idinga ukushintshwa.

2. Uwonga uphethiloli ompofu

Njengenkinga engenhla, lapho idrayivu yokukhahlela ithumela ulwazi olungalungile kukhompuyutha yohambo, isilinganiso somoya/samafutha sizobe sinemba. Kulokhu, injini ngeke igcine ngokumisa, kodwa izophinde idle uphethiloli owengeziwe kunalokho obekulindelwe. Umphumela ongemuhle walesi simo ukuthi uphethiloli ongashile uzophuma epayipini le-exhaust njengentuthu emnyama. Uma uqaphela ukuthi imoto yakho ibhema intuthu emnyama futhi ukusetshenziswa kwakho kukaphethiloli kwehle kakhulu ezinsukwini zamuva, bona umakhenikha ukuze akwazi ukuxilonga inkinga futhi abuyisele i-throttle actuator uma kudingeka.

3. Injini ivamise ukuma

Kwezinye izimo, i-throttle actuator eyonakele izophazamisa ukusebenza kwenjini ngemva kokuba ingaphansi komthwalo. Lapho ijubane lokungenzi lutho liba phansi kakhulu, injini iyacisha noma izitebele. Kwezinye izimo, lokhu kubangelwa ukuthi i-actuator ingasebenzi nhlobo, okusho ukuthi umakhenikha kuzomele ayishintshe maduze ukuze injini yakho isebenze ngendlela okufanele futhi. Ezimotweni eziningi ezintsha, amaloli nama-SUV, ukwehluleka kwe-throttle actuator kuzobangela ukuthi ikhodi yephutha ye-OBD-II igcinwe ku-ECU. Uma ubona noma yiziphi izimpawu zalezi ezingenhla, noma ucabanga ukuthi unenkinga nge-throttle actuator yakho, xhumana ne-ASE Certified Mechanic yangakini ukuze ikwazi ukulanda lawa makhodi amaphutha futhi inqume inkambo efanele ukuze imoto yakho iphinde isebenze futhi. kufanele.
