Inzwa ye-crankshaft yenzani emotweni
Iqhaza le-automobile crankshaft sensor emotweni ikakhulukazi lihlanganisa lezi zici ezilandelayo:
I-Ignition Timing Control : Izinzwa zendawo ye-Crankshaft ziqapha indawo yokuzungezisa kwe-crankshaft futhi zinikeze idatha ebalulekile kuYunithi yokulawula injini (ECU) ukusiza ukunquma isikhathi esilungile sokudubula isilinda ngasinye. Lokhu kuqinisekisa ukuthi ipulaki lenhlansi liyathungela lapho ipiston ifika ku-TDC futhi ingxube icindezelwa ukuze ibe sezingeni eliphezulu, ngaleyo ndlela kuzuzwe ukusha okunamandla kaphethiloli kanye nokwenza ngcono amandla enjini nomnotho. .
Ukulawula umjovo kaphethiloli : Inzwa yendawo ye-crankshaft iphinde isetshenziselwe ukulawula isistimu yomjovo kaphethiloli, ukuqinisekisa ukuthi uphethiloli ukhishwa ngesikhathi esifanele ukuze uhlangabezane nezidingo zenjini. Ngokuqapha indawo ye-crankshaft, isistimu ingalawula ngokunembe kakhudlwana inani lomjovo kaphethiloli ukuze kuqinisekiswe imiphumela engcono kakhulu yokusha ngaphansi kwezimo zokusebenza ezihlukene. .
Ukuqala nokusebenza kwenjini : Ngesikhathi injini iqala, inzwa yokuma kwe-crankshaft iqinisekisa ukuthi injini iqala ngesikhathi esifanele futhi igcina ukusebenza okuzinzile. Ngaphezu kwalokho, ibandakanyeka ekulawuleni isivinini esingenzi lutho nokulawula ukuhwamuka kukaphethiloli, ukusiza i-ECU ukulungisa ukuvuleka kwe-throttle noma indawo ye-actuator engenzi lutho ukuze kugcinwe isivinini senjini esingenzi lutho. .
: Uma inzwa yendawo ye-crankshaft yehluleka, isistimu yokulawula i-elekthronikhi yemoto ingakwazi ukubona futhi ibonise inkinga ngokufunda ikhodi yephutha, ukusiza ukuhlonza amaphutha nokulungiswa kochwepheshe.
Inzwa yokuma kwe-crankshaft isebenza ukuze inikeze idatha ebalulekile ohlelweni lokuphatha injini ngokulinganisa ngokunembile nokubika indawo nesivinini se-crankshaft. Ithola futhi ikhiphe amasignali ephoyinti lokuma, amasignali e-crankshaft Angle, namasignali esivinini senjini, afakwa ku-ECU ngesikhathi sangempela, lapho i-ECU ibala khona isikhathi esilungile sokudubula kanye nevolumu yomjovo kaphethiloli kusilinda ngasinye. .
Izinzwa ze-crankshaft yezimoto (i-CPS noma i-CKP) zidlala indima ebalulekile ezimotweni. Ingenye yezinzwa ezibaluleke kakhulu ohlelweni lokulawula injini, futhi imisebenzi yayo eyinhloko ihlanganisa:
Isivinini senjini : Inzwa ye-crankshaft ingakwazi ukuqapha isivinini sokujikeleza kwe-crankshaft ngesikhathi sangempela, ukuze ibale kahle isivinini senjini. Lolu lwazi lubaluleke kakhulu ekunqumeni izinga lomjovo kaphethiloli kanye ne-Engle yokuthungela kusengaphambili.
Thola indawo ye-piston : Ngokuzwa i-engeli yokuzungeza ye-crankshaft, inzwa ye-crankshaft ingakwazi ukunquma indawo ethile yepiston kusilinda. Lokhu kubalulekile ukulawula isikhathi sokuvutha nokujova uphethiloli.
Isimo sokusebenza kwenjini yokuqapha : ingakwazi ukuqapha isimo sokusebenza kwenjini, uma isitholakele njengomlilo noma ukuntuleka komlilo namanye amaphutha, izothatha ngokushesha isignali engavamile, futhi ifike ngesikhathi kuyunithi yokulawula injini ukuze ithumele ulwazi oluyisixwayiso.
Thuthukisa ukusebenza kahle kokukhipha ukungcola : Ngokulawula okunembile kwendawo ye-crankshaft, inqubo yokushiswa kukaphethiloli ingathuthukiswa, ukukhishwa kwezinto eziyingozi kungancishiswa, kanye nokusebenza kahle kwemoto .
Eminye imisebenzi : Ngaphezu kokulawula umjovo kaphethiloli nokuthungela, inzwa ye-crankshaft iphinde ibambe iqhaza ekulawuleni isivinini esingenzi lutho, ukulawula ukujikeleza kabusha kwegesi ephumayo, nokulawula ukuhwamuka kukaphethiloli.
Uhlobo nendawo yokufaka
Kunezinhlobo ezimbili eziyinhloko zezinzwa ze-crankshaft: uhlobo lwe-magnetic pulse kanye nohlobo lweHholo. Izinzwa ze-Magnetic pulse zivame ukufakwa eduze kwendlu yokudlulisela ye-flywheel, kuyilapho izinzwa zehholo zifakwa eduze kwe-crankshaft pulley ekugcineni kwe-crankshaft noma endlini yokudlulisela eduze kwe-flywheel. Indawo yokufaka ngqo izohluka kuye ngemodeli nomklamo.
