Uyini umsebenzi wemitha yokugeleza komoya emotweni?
Kala ivolumu yomoya ongenayo bese ulawula ukufakwa kukaphethiloli
Umsebenzi oyinhloko wemitha yokuhamba komoya yemoto ukukala ukuhamba komoya okungena enjinini nokudlulisa isignali kuyunithi yokulawula kagesi (i-ECU) ukuze kulawulwe ngokunembile ivolumu yokufaka uphethiloli, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokushisa, kuncishiswe ukukhishwa komoya, futhi kuthuthukiswe ukusebenza kwamandla. Imisebenzi ethile ifaka:
- Ukuqapha ngesikhathi sangempela kwevolumu yomoya ongenayo: Ngokubona ijubane lokugeleza komoya kusetshenziswa inzwa ye-thermistor noma ye-vortex, inani elibonakalayo liguqulwa libe isignali kagesi (njengokushintsha kokumelana noma isignali yemvamisa) ukuqinisekisa ukuthi i-ECU ithola idatha enembile.
- Ukulawula isilinganiso somoya-fuel: I-ECU ilungisa ngokuguquguqukayo ivolumu yokufaka uphethiloli ngokusekelwe kudatha yokugeleza komoya, igcina isilinganiso somoya-fuel esifanele (cishe u-14.7:1), igwema ukuceba ngokweqile (okubangela ukunqwabelana kwekhabhoni kanye nokusetshenziswa kukaphethiloli okwandisiwe) noma ukusha okunciphile kakhulu (okuholela ekulahlekelweni kwamandla).
- Ukuzivumelanisa nezimo zokusebenza ezahlukene: Isabela ngokushesha (ngaphakathi kwama-millisecond) ngesikhathi sokungasebenzi, ukusheshisa, noma ukwehla kwejubane, isibonelo, ukwandisa ukufakwa kukaphethiloli ukuze kuthuthukiswe amandla ngesikhathi sokusheshisa kanye nokugcina umoya ozinzile ukungenisa ukuze kuvinjelwe ukumiswa kwenjini ngesikhathi sokungasebenzi.
Uma imitha yokugeleza komoya emotweni ingasebenzi kahle, izimpawu eziyinhloko zifaka:
- Ukungazinzi kokusebenza
- Ukusheshisa okubuthakathaka
- Ukusetshenziswa kukaphethiloli okwandisiwe
- Intuthu emnyama evela epayipini lokukhipha umoya
- Ukuma noma ukudlidliza kwenjini ngezikhathi ezithile
- Izimpawu ezithile:
Izimpawu zephutha eliyinhloko
Imitha yokugeleza komoya eyonakele izobangela ukutholakala komthamo womoya ongenayo ngendlela engajwayelekile, okuzothinta ukulawulwa kokujova uphethiloli futhi kuholele ezinkingeni ezivamile:
- Ukungazinzi kokusebenza kahle: Injini iyanyakaza ngokuphawulekayo uma ingasebenzi noma ngesivinini esiphansi, ngama-RPM ashintshashintshayo, ngisho nokuma kancane (ngenxa yokungakwazi kwe-ECU ukulungisa ngokunembile isilinganiso sengxube).
- Ukusheshisa okubuthakathaka: Injini isabela kancane uma inyathela i-accelerator, okwenza kube nzima ukuyidlula (ikakhulukazi uma ijubane liphezulu, njengalapho ijubane lidlula i-120 km/h kanye ne-RPM yehla).
- Ukwenyuka kokusetshenziswa kukaphethiloli okungajwayelekile: Ukusetshenziswa kukaphethiloli kukhuphuka ngo-10%-15%, ngenxa yokubalwa okungalungile kwevolumu yokufaka uphethiloli, okuholela ekushiseni okucebile ngokweqile (okubangela ukunqwabelana kwekhabhoni kanye nokusetshenziswa kukaphethiloli okwandisiwe) noma ukushisa okunciphile kakhulu (okubangela ukulahlekelwa amandla).
- Intuthu emnyama evela epayipini lokukhipha umoya: Ukusha okungaphelele kukhiqiza intuthu emnyama eningi, ehambisana nokungcola okukhulu kokukhipha umoya (ukukhishwa kwe-HC kungadlula i-500 ppm).
- Ukuma noma ukuxega kwenjini ngezikhathi ezithile: Injini iyanyakaza noma imise ngokuzumayo ngesikhathi sokushayela ngesivinini esikhulu, futhi isebenza ngokujwayelekile lapho ingasebenzi (ngenxa yokungalungi kokukhishwa kwesignali yesivinini esiphezulu).
Eminye imiphumela ehlobene
- Isibani sesikhombisi sephutha: Ideshibhodi ikhanyisa isikhombisi sephutha senjini (njengesixwayiso esithi "SERVICE ENGINE").
- Ubunzima bokuqala: Kunzima ukukhanyisa injini ekuqaleni okubandayo ngenxa yokungakwazi kwe-ECU ukulinganisa isilinganiso esifanele somoya nophethiloli.
- Ingozi yomonakalo wesikhathi eside: Amaphutha aqhubekayo angase abhebhethekise ukuguguleka kwenjini futhi anciphise amandla okucindezela isilinda.
Uma kuvela izimpawu ezingenhla, kunconywa ukuthi zilungiswe ngokushesha ukuze kugwenywe ukulimaza izingxenye ezifana ne-three-way catalytic converter.
Imitha yokugeleza komoya emotweni ingahlanzwa, kodwa ngokuvamile kudingeka ukuyihlanza kuphela uma ingcolile noma inephutha.
Ukuhlanzeka
- Ingahlanzwa: Lapho ikhabhoni noma ukungcola kuqongelela ezinzwa zangaphakathi zemitha yokugeleza komoya, ukuhlanza kungabuyisela ukunemba kwayo kokulinganisa futhi kuxazulule izinkinga ezifana nokuntuleka kwamandla enjini kanye nokusetshenziswa kukaphethiloli okwandisiwe.
- Akudingeki: Emotweni enakekelwe kahle, imitha yokugeleza komoya ivame ukuhlanzeka futhi ayidingi ukuhlanzwa njalo.
Izindlela zokuhlanza kanye nezinyathelo zokuphepha
- Indawo kanye nokuhlukaniswa: Imitha yokugeleza komoya ivame ukutholakala esihlungini somoya ngemuva kwepayipi lokungenisa. Ukuhlukaniswa kudinga ukusetshenziswa kwamathuluzi ochwepheshe ukuze kugwenywe umonakalo.
- Umsebenzi wokuhlanza:
- Ukuhlanza kwangaphandle: Sebenzisa indwangu engalukiwe ecwiliswe otshwaleni ukuze usule amabala kawoyela ekhasejini.
- Izinzwa zangaphakathi: Sebenzisa ama-swab kakotini acwiliswe ku-alcohol engu-95% noma ngaphezulu noma izinto zokuhlanza ze-elekthronikhi ezinikezelwe ukusula ngobumnene izinzwa ze-platinum wire/thermistor. Ungasebenzisi izinto zokuhlanza ezibolayo (njengezinto zokuhlanza ze-carburetor).
- Ukuhlanza igridi: Sebenzisa ibhulashi elithambile ukuhlanza ukungcola okugridi.
- Ukomisa nokufaka kabusha: Sebenzisa umshini wokomisa izinwele ukuze womise kahle izingxenye, uqinisekise ukuthi zoma ngokuphelele ngaphambi kokufaka kabusha, futhi unake ukuqinisa ukuxhumeka kwentambo.
- Imininingwane yobuchwepheshe:
- Ukukhetha ama-ejenti okuhlanza: Ama-ejenti okuhlanza kagesi aguquguqukayo kuphela noma i-ethanol engamanzi (ukugxila ≥ 95%) avunyelwe. Sebenza ngobumnene: Izingxenye zenzwa zithambile. Amandla okusula kufanele abe lula ukuze kugwenywe umonakalo.
Ngemva kokufaka, hlola: Ngemva kokuhlanza, qala injini bese ubheka isimo sokusebenza. Uma kuvela ikhodi yephutha, yenza ukufunda okuguquguqukayo kwe-ECU.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
