Umsebenzi wenzwa yokucindezela kokuthatha imoto
Gada ingcindezi eningi ethathwayo
Inzwa yokucindezela okuthathwayo ixhunywe ku-multifold intake ngeshubhu ye-vacuum ukuze kutholwe ushintsho oluphelele lwengcindezi ku-multifold intake ngemuva kwe-throttle valve ngesikhathi sangempela. Lezi zinguquko zokucindezela zihlobene eduze nesivinini nomthwalo wenjini, futhi izinzwa ziguqula lezi zinguquko zemishini zibe amasignali kagesi adluliselwa ku-ECU.
Lungiselela umjovo kaphethiloli
Ngokusekelwe kusignali yokucindezela enikezwe inzwa, i-ECU ibala ngokunembile inani likaphethiloli elidingwa injini. Lapho amandla enjini akhuphuka, ingcindezi eningi ethathwayo iyehla, isignali yokuphuma kwenzwa iyanda, futhi i-ECU inyusa umthamo womjovo kaphethiloli ngendlela efanele. Uma kungenjalo, izokwehla. Lokhu kulungiswa okuguquguqukayo kuqinisekisa ukusebenza kahle kwenjini ngaphansi kwezimo ezihlukene zokusebenza.
Lawula isikhathi sokubasa
Inzwa yokucindezela kokuthatha futhi isiza i-ECU ukulungisa isikhathi sokuthungela. Lapho injini ikhuphuka, i-Engeli yokuthungela izobambezeleka ngendlela efanele. Uma umthwalo uncishisiwe, i-Engeli engaphambili yokuvutha izoqhubekela phambili. Lokhu kulungiswa kusiza ukuthuthukisa ukusebenza kwamandla enjini nokonga kukaphethiloli.
Isibalo sokugeleza komoya esisizayo
Kusistimu yomjovo kaphethiloli wohlobo D, inzwa yokucindezela kokuthatha isetshenziswa ngokuhambisana nemitha yokugeleza komoya ukukala ivolumu yokungena ngokungaqondile, ngaleyo ndlela kubalwe ukugeleza komoya ngokunembe kakhudlwana. Lo msebenzi wokubambisana uthuthukisa futhi ukujova kukaphethiloli nokusebenza kwenjini.
Ukutholwa kwamaphutha nokuvikela
Inzwa yokucindezela kokuthatha iyakwazi ukubona izinguquko zengcindezi engavamile ku-manifold yokuthatha, njengama-clogs noma ukuvuza, nokuthumela amasignali ku-ECU. Lokhu kusiza ukubona ukwehluleka kwenjini ngesikhathi futhi uthathe izinyathelo zokuvikela ukugwema ukulimala okwengeziwe.
Izinhlobo nezimiso zokusebenza
Izinzwa zokucindezela ezivamile zokuthatha zihlanganisa izinhlobo ze-varistor ne-capacitive. Inzwa ye-varistor ishintsha ukumelana ngokuguqulwa kwe-silicon diaphragm futhi ikhiphe isignali kagesi. I-capacitive sensor ishintsha inani le-capacitance ngokuguqulwa kwe-diaphragm futhi ikhiphe isignali ye-pulse. Zombili izinzwa zisetshenziswa kakhulu ezimotweni zesimanje ngokunemba kwazo okuphezulu nokuphendula okusheshayo.
Fingqa
Inzwa yokucindezela kokuthatha ingenye yezingxenye eziyinhloko zesistimu yokulawula injini yemoto, indima yayo ayigcini nje kuphela ekuhloleni ingcindezi, kodwa futhi ihileleke ekujovweni kukaphethiloli, isikhathi sokubasa, ukubala ukugeleza komoya kanye nokutholwa kwamaphutha. Ngokulawula ngokunembile lezi zinhlaka, izinzwa zithuthukisa kakhulu ukusebenza kwenjini, ukonga kukaphethiloli nokukhipha umoya.
I-Automotive intake pressure sensor (i-intake pressure sensor) ingenye yezingxenye eziyinhloko zesistimu yomjovo kaphethiloli, ukwehluleka kwayo kuzodala iyunithi yokulawula injini (ECU) ayikwazi ukulungisa ngokunembile isilinganiso se-air-fuel. Okulandelayo izimpawu eziyinhloko nezimbangela zephutha:
Isethulo sophawu olubalulekile
Ubunzima noma ukungakwazi ukuqalisa injini
Amasignali enzwa engavamile azobangela i-ECU ukuthi yehluleke ukubala inani elilungile lomjovo kaphethiloli, okuthinta ngokuqondile ukuthungela nokujova kukaphethiloli.
Uma umugqa wezinzwa uphukile noma ufushane, i-ECU ingase ilahlekelwe ngokuphelele idatha yokucindezela kokuthatha, okuholela ekuhlulekeni kokuqala.
Ukuphuma kwamandla okungajwayelekile
ukusheshisa okungekuhle noma ukwehla kwamandla : inzwa ayikwazi ukulungisa isignali ngokushintsha kwedigri ye-vacuum, futhi i-ECU ibala kabi ukungenisa komoya, okuholela ekuphambukeni komthamo womjovo kawoyela.
isivinini esingavamile sokungenzi lutho : Uma ingxube isiwugqinsi kakhulu noma izacile kakhulu, injini ingase idlikize noma ishintshe isivinini.
i-anomaly yomlilo
Intuthu emnyama evela epayipini le-exhaust : ingxube ijiyile kakhulu ukubanga ukusha okungaphelele, okuvame ukubonakala ngokusheshisa okusheshayo.
Ukushisa kwamapayipi okungenisa : Uma ingxube izacile kakhulu, igesi engashi ivutha epayipini elingenisayo.
Ukuhlukaniswa kwembangela yephutha
Inzwa ngokwayo
I-gauge yobunzima yangaphakathi noma ukwehluleka kwesekethe (isb. ukwehluleka kwe-semiconductor strain gauge).
I-voltage yesiginali yokuphumayo idlula ububanzi obujwayelekile (njenge-voltage drift).
ukwehluleka okuhlobene kwangaphandle
I-vacuum hose ivinjiwe noma iyavuza, okuthinta ukudluliswa kwengcindezi.
Ukufakwa okungalungile kwendandatho yophawu kuholela ekuvinjweni kwe-inlet yokucindezela (ukuguqulwa kwesignali ngesikhathi sokucindezela).
Isiphakamiso sokuxilonga
Ukuhlolwa kokuqala
Bheka ukuthi isibani sephutha sivuliwe yini (amanye amamodeli azocupha ikhodi yephutha ye-OBD).
Hlola uxhumo lwamapayipi evacuum nezintambo zenzwa.
Ukuhlolwa kochwepheshe
Sebenzisa ukuxilongwa ukuze ufunde ukusakazwa kwedatha yesikhathi sangempela futhi uqhathanise amanani okucindezela ajwayelekile.
Hlola ukuthi ingabe i-voltage yokuphuma kwenzwa iyahluka ngokuvuleka kwe-throttle.
ithiphu : Uma izimpawu ezingenhla zihambisana namakhodi ephutha (afana ne-P0105/P0106), inzwa namasekhethi ahlobene kufanele kuqale kuhlolwe. Ukunganakwa isikhathi eside kungase kubangele umonakalo kusiguquli se-catalytic yezindlela ezintathu noma ekwenyukeni okukhulu kokusetshenziswa kukaphethiloli.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko kule sayithi!
