Kusho ukuthini lokhu?

Le yikhodi enenkinga yokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Lokhu kungafaka, kodwa kungagcini lapho, iFord, Mazda, Smart, Land Rover, Dodge, Ram, njll. Naphezu kwemvelo ejwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngohlobo lwemodeli, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Lapho ikhodi ye-P064D iqhubeka, kusho ukuthi imodyuli yokulawula amandla we-powertrain (i-PCM) ithole iphutha langaphakathi lokwenza iprosesa ngesekethe ye-oxygen heated (HO2S) yomugqa wokuqala wezinjini. Abanye abalawuli bangathola nephutha langaphakathi le-PCM (nge-HO2S yebhange elilodwa) bese kubangela ukuthi kugcinwe i-P064D.

IBhange 1 lisho iqembu lenjini eliqukethe inombolo eyisilinda eyodwa.

I-HO2S iqukethe i-zirconia sensing element kanye negumbi elincane lesampula elifakwe endlini yensimbi evulekile. Isici sokuzwa sixhuma ezintanjeni ze-HO2S harness nama-electrode amancane e-platinum. Inzwa ye-oxygen sensor (HO2S) ixhunywe kwihhanisi yokulawula injini, enikeza i-PCM idatha ehlobene nephesenti le-oksijini ekuqothulweni kwenjini uma kuqhathaniswa ne-oxygen esemoyeni.

Inzwa ye-HO2S ekhuphukayo itholakala kwipayipi lokukhipha umoya (phakathi kwe-exhaust manifold kanye nesiguquli se-catalytic). Indlela evame kakhulu yokufeza lokhu iwukufaka inzwa ngokuqondile ku-threaded bushing eshiselwe kwipayipi yokukhipha. I-threaded bushing ibekwe kupayipi eliphansi endaweni ekahle kakhulu futhi nge-engeli elula kakhulu yokufinyelela nokusebenza kwenzwa okuphezulu. Ukususwa nokufakwa kwezinzwa zomoya-mpilo ezinentambo kuzodinga ama-wrenches aklanywe ngokukhethekile noma amasokhethi, kuye ngokusetshenziswa kwemoto. I-HO2S ingabuye ivikelwe ngezikhonkwane ezinentambo (namantongomane) ashiselwe epayipini lokukhipha umoya.

Amagesi okukhipha adudulwa anqwabelene no-exhaust ayongena empophomeni lapho edlula khona ku-HO2S engenhla. Amagesi okukhipha adlula emigodini eklanyelwe ngokukhethekile ezindlini zensimbi zenzwa ye-oxygen (HO2S) nangesici sokuzwa. Umoya ohelezayo udonselwa egumbini elincane lesampula maphakathi nenzwa ngezimbobo eziholayo. Kuleli gumbi, umoya uyashiswa, okwenza ukuthi ion ikhiqize (amandla) amandla kagesi. Umehluko phakathi kokuhlushwa kwama-molecule e-oksijini kugesi wokukhipha umoya nomoya omile (odonselwe ku-HO2S) kubangela ukuguquguquka kokuhlushwa kwama-oxygen ions (ngaphakathi kwenzwa). Lokhu kudlidlizela kubangela ukuthi i-ioni yomoya-mpilo (ngaphakathi kwe-HO2S) igxume (ngokushesha nangezikhathi ezithile) kusuka kolunye ungqimba lweplathinamu kuye kolandelayo. Lapho kudonswa ion oksijini ihamba phakathi kwezendlalelo zeplathinamu, ibangela ushintsho lwamandla. Lezi zinguquko zamandla ombane zibonwa yi-PCM njengezinguquko ekugxileni komoya-mpilo kumagesi okukhipha futhi kukhombisa ukuthi injini isebenza ngokuncika (uphethiloli omncane kakhulu) noma ocebile (uphethiloli omningi kakhulu). Lapho i-oksijeni eyengeziwe ikhona ekuqothulweni (isimo esinciphile), amandla kagesi avela ku-HO2S aba phansi. Lapho umoya omncane we-oksijini ukhona ekuqothulweni (isimo esinothile), ukuphuma kwamandla kuphakeme. Le datha isetshenziswa yi-PCM, phakathi kwezinye izinto, ukubala isu likaphethiloli nesikhathi sokushisa.

Okokufaka okufakwayo kwe-HO2S kuvamise ukusukela kuma-millivolts ayi-100 kuye kwangama-900 (1 kuye ku-9 volts) lapho injini ingasebenzi futhi i-PCM ikwimodi ye-loop evaliwe. Ekusebenzeni kwe-loop evaliwe, i-PCM ithatha okokufaka kusuka ku-HO2S enyukayo ukulawula ububanzi be-pulse injector pulse futhi (ekugcineni) ukulethwa kukaphethiloli. Lapho injini ingena kumodi evulekile yeluphu (ukuqala okubandayo nezimo ezivulekile ezivulekile), isu le-fuel lihlelwe ngaphambilini.

Amaprosesa wokuqapha imodyuli yangaphakathi anesibopho semisebenzi ehlukahlukene yokuzihlola nokuziphendulela kwemodyuli yokulawula kwangaphakathi. Amasiginali wokufaka nowokukhiphayo we-HO2S azihlola wona futhi aqhutshwa ngokuqhubekayo yi-PCM nabanye abalawuli abafanele. Imodyuli yokulawula ukudluliswa (TCM), i-traction control module (TCSM), kanye nezinye izilawuli nazo ziyaxhumana ne-HO2S.

Ngaso sonke isikhathi lapho ukuthungela kuvuliwe futhi i-PCM inikwa amandla, kuhlolwa i-HO2S. Ngaphezu kokwenza isivivinyo sakho kwisilawuli sangaphakathi, i-Controller Area Network (i-CAN) nayo iqhathanisa amasiginali avela kumodyuli ngayinye ukuqinisekisa ukuthi isilawuli ngasinye sisebenza njengoba kulindelwe. Lezi zivivinyo zenziwa ngasikhathi sinye.

Uma i-PCM ithola ukungahambisani kwangaphakathi ekusebenzeni kwe-HO2S, ikhodi engu-P064D izogcinwa futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa. Ngaphezu kwalokho, uma i-PCM ithola inkinga phakathi kwanoma yibaphi abalawuli abasebhodini abakhombisa iphutha langaphakathi le-HO2S, kuzogcinwa ikhodi ye-P064D futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa. Kungathatha imijikelezo eminingi yokwehluleka ukukhanyisa i-MIL, ngokuya ngobukhulu obubonakalayo bokungasebenzi kahle.
