Umsebenzi wenzwa yokucindezela kokungenisa izimoto
Ingcindezi yokulawula ukungenisa okuningi
Inzwa yokucindezela kokungenisa ixhunywe ku-incase manifold ngepayipi le-vacuum ukuze ibone ushintsho oluphelele lokucindezela ku-incase manifold ngemuva kwe-throttle valve ngesikhathi sangempela. Lezi zinguquko zokucindezela zihlobene eduze nesivinini kanye nomthwalo wenjini, futhi izinzwa ziguqula lezi zinguquko zemishini zibe izimpawu zikagesi ezidluliselwa ku-ECU.
Lungiselela ukujova uphethiloli
Ngokusekelwe esignalini yokucindezela enikezwa yi-sensor, i-ECU ibala ngokunembile inani likaphethiloli elidingwa yinjini. Lapho umthwalo wenjini ukhuphuka, ingcindezi ye-input manifold iyancipha, isignali yokukhipha i-sensor iyanda, kanti i-ECU inyusa ivolumu yokufaka uphethiloli ngokufanele. Ngaphandle kwalokho, izoncipha. Lokhu kulungiswa okunamandla kuqinisekisa ukusebenza kahle kwenjini ngaphansi kwezimo zokusebenza ezahlukene.
Isikhathi sokulawula ukushisa
Inzwa yokucindezela kokungenisa iphinde isize i-ECU ukulungisa isikhathi sokusha. Lapho umthwalo wenjini ukhuphuka, i-Angle yokudlulisela phambili yokusha izobambezeleka ngokufanele. Uma umthwalo uncishisiwe, i-Angle yokudlulisela phambili yokusha izoqhubeka. Lokhu kulungiswa kusiza ekuthuthukiseni ukusebenza kwamandla enjini kanye nokonga uphethiloli.
Ukubalwa kokugeleza komoya okusizayo
Kuhlelo lokujova uphethiloli lohlobo D, inzwa yokucindezela kokungenisa isetshenziswa kanye nemitha yokugeleza komoya ukukala ivolumu yokungenisa ngokungaqondile, ngaleyo ndlela kubalwe ukugeleza komoya ngokunembe kakhudlwana. Lo msebenzi wokubambisana uthuthukisa kakhulu ukujova uphethiloli kanye nokusebenza kwenjini.
Ukutholwa nokuvikelwa kwamaphutha
Inzwa yokucindezela kokungenisa iyakwazi ukubona izinguquko ezingavamile zokucindezela ku-intake manifold, njengokuvaleka noma ukuvuza, bese ithumela izimpawu ku-ECU. Lokhu kusiza ukubona ukwehluleka kwenjini ngesikhathi futhi kuthathe izinyathelo zokuzivikela ukuze kugwenywe umonakalo owengeziwe.
Izinhlobo kanye nemigomo yokusebenza
Izinzwa zokucindezela kokungenisa ezivamile zifaka phakathi izinhlobo ze-varistor kanye ne-capacitive. Inzwa ye-varistor ishintsha ukumelana ngokuguqulwa kwe-diaphragm ye-silicon bese ikhipha isignali kagesi. Inzwa ye-capacitive ishintsha inani le-capacitance ngokuguqulwa kwe-diaphragm bese ikhipha isignali ye-pulse. Zombili izinzwa zisetshenziswa kabanzi ezimotweni zesimanje ngenxa yokunemba kwazo okuphezulu kanye nokusabela okusheshayo.
Fingqa
Inzwa yokucindezela kokungenisa ingenye yezingxenye eziyinhloko zesistimu yokulawula injini yezimoto, indima yayo ayigcini nje ngokuqapha ingcindezi, kodwa futhi ihilelekile ekufakweni kukaphethiloli, isikhathi sokusha, ukubalwa kokugeleza komoya kanye nokutholakala kwamaphutha. Ngokulawula ngokunembile lezi zinhlaka, izinzwa zithuthukisa kakhulu ukusebenza kwenjini, ukonga uphethiloli kanye nokukhishwa komoya.
Inzwa yokucindezela kokungenisa kwezimoto (inzwa yokucindezela kokungenisa) ingenye yezingxenye eziyinhloko zesistimu yokujova uphethiloli, ukwehluleka kwayo kuzokwenza ukuthi iyunithi yokulawula injini (i-ECU) ingakwazi ukulungisa ngokunembile isilinganiso somoya-uphethiloli. Okulandelayo yizimpawu eziyinhloko nezimbangela zephutha:
Ukwethulwa kwezimpawu eziyinhloko
Ubunzima noma ukungakwazi ukuqala injini
Izimpawu zenzwa ezingavamile zizokwenza i-ECU yehluleke ukubala inani elifanele lokufakwa kukaphethiloli, okuthinta ngqo ukuthungela kanye nokufakwa kukaphethiloli.
Uma umugqa wesenzwa uphukile noma unqanyuliwe, i-ECU ingase ilahlekelwe ngokuphelele idatha yengcindezi yokungenisa, okuholela ekwehlulekeni kokuqala.
Ukukhishwa kwamandla okungajwayelekile
ukusheshisa okungekuhle noma ukwehla kwamandla: inzwa ayikwazi ukulungisa isignali ngokushintsha kwezinga le-vacuum, futhi i-ECU ibala kabi ukungena komoya, okuholela ekuphambukeni kwenani lomjovo kawoyela.
isivinini esingaguquki sokungenzi lutho : Uma ingxube ijiyile kakhulu noma incane kakhulu, injini ingase iqhume noma isheshise ukushintshashintsha.
i-anomaly yokushisa
Intuthu emnyama evela epayipini lokukhipha umoya: ingxube ikhulu kakhulu ukuthi ingadala ukusha okungaphelele, okuvame ukubonakala ekusheshiseni okusheshayo.
Ukushisa kwepayipi lokungenisa: Uma ingxube isincane kakhulu, igesi engashiswanga iyavutha epayipini lokungenisa.
Ukuhlukaniswa kwezimbangela zephutha
Inzwa ngokwayo
Isilinganiso sokucindezeleka kwangaphakathi noma ukwehluleka kwesekethe (isb. ukwehluleka kwesilinganiso sokucindezeleka se-semiconductor).
I-voltage yesignali yokukhipha idlula ububanzi obujwayelekile (njengokukhukhuleka kwe-voltage).
ukwehluleka kwangaphandle okuhlobene
Ipayipi le-vacuum livinjiwe noma liyavuza, okuthinta ukudluliselwa kwengcindezi.
Ukufakwa okungalungile kwendandatho yokuvala kuholela ekuvinjweni kokungena kwengcindezi (ukuguqulwa kwesignali ngesikhathi sokucindezela).
Isiphakamiso sokuxilonga
Ukuhlolwa kokuqala
Bheka ukuthi isibani sephutha sivuliwe yini (amanye amamodeli azoqala ikhodi yephutha ye-OBD).
Hlola ukuxhumeka kwamapayipi e-vacuum kanye ne-sensor wiring harness.
Ukuhlolwa kobungcweti
Sebenzisa ukuxilonga ukuze ufunde ukusakazwa kwedatha yesikhathi sangempela bese uqhathanisa amanani ajwayelekile okucindezela.
Hlola ukuthi i-voltage yokukhipha inzwa iyahlukahluka yini ngokuvula kwe-throttle.
Icebiso: Uma izimpawu ezingenhla zihambisana namakhodi ephutha (njenge-P0105/P0106), inzwa kanye namasekethe ahlobene kufanele kuhlolwe kuqala. Ukunganakwa kwesikhathi eside kungabangela umonakalo ku-catalytic converter enezindlela ezintathu noma ukwanda okukhulu kokusetshenziswa kukaphethiloli.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
