Iyini indima ye-automotive camshaft sensor
I-Camshaft position sensor idlala indima ebalulekile enjinini yemoto, umsebenzi oyinhloko ukuqoqa isignali yendawo ye-camshaft bese iyifaka ku-electronic control unit (ECU) ukuze kunqunywe isikhathi sokubasa nesikhathi sokujova uphethiloli. Ngokuthola indawo yokujikeleza kwe-camshaft, inzwa inquma isikhathi sokuvula nesokuvala kwe-valve, ngaleyo ndlela izuze ukulawula okunembile kwenjini. .
Isimiso sokusebenza senzwa yesikhundla se-camshaft sisekelwe ku-electromagnetic induction noma ubuchwepheshe bokungeniswa kwe-photoelectric. Lapho i-camshaft izungeza, inzwa ithola iqhubu noma inotshi ku-camshaft futhi ikhiqize isignali kagesi ehambisanayo. Ngemva kokuthola lezi zimpawu, i-ECU inquma isikhathi sokuthungela nesikhathi sokujova uphethiloli ngokubala nokucubungula, ukuze kuzuzwe ukulawula okunembile kwenjini. .
Ukunemba nokuthembeka kwezinzwa zokuma kwe-camshaft kubalulekile ekusebenzeni kwenjini nokonga kukaphethiloli. Uma inzwa yehluleka, ingaholela ekushiseni okungalungile, ukuncipha komthamo kaphethiloli, futhi mhlawumbe nenjini engasebenzi kahle. Ngakho-ke, ukuhlolwa okuvamile nokugcinwa kwenzwa ye-camshaft isikhundla kubaluleke kakhulu.
I-camshaft sensor iyingxenye yemoto ebalulekile, esetshenziselwa kakhulu ukuthola indawo nesivinini se-camshaft, ukuze kuqinisekiswe ukusebenza okuvamile kwenjini. I-Camshaft Sensor, eyaziwa nangokuthi i-Camshaft Position Sensor (CPS) noma i-Cylinder Identification Sensor (CIS), umsebenzi wayo oyinhloko ukuqoqa amasignali esikhundla se-valve camshaft. Lawa masignali afakwa ku-electronic control Unit (ECU). Kulawa masiginali, i-ECU iyakwazi ukuhlonza i-TDC yokuminyanisa yesilinda 1 yokulawula umjovo kaphethiloli olandelanayo, ukulawula isikhathi sokuvutha kanye nokulawula ukuwohloka komlilo.
Isakhiwo kanye nomgomo wokusebenza
Kunezinhlobo eziningi zezinzwa zokuma kwe-camshaft, okuhlanganisa i-photoelectric kanye ne-magnetic induction. Inzwa ye-Photoelectric yakhiwa ngokuyinhloko idiski yesiginali, ijeneretha yesiginali nomsabalalisi, futhi ikhiqiza isignali nge-diode ekhipha ukukhanya kanye ne-photosensitive transistor. Uhlobo lokungeniswa lukazibuthe lusebenzisa umphumela weHholo noma isimiso sokungeniswa kazibuthe ukukhiqiza amasiginali, avame ukuhlukaniswa abe uhlobo lweHholo kanye nohlobo lwe-magnetoelectric.
Indawo yokufaka
Inzwa yesikhundla se-camshaft ivame ukufakwa ekugcineni kwekhava ye-camshaft, ngokuphambene nomkhawulo ongaphambili we-intake kanye ne-exhaust camshaft. Lo mklamo uqinisekisa ukuthi inzwa ingakwazi ukuqoqa ngokunembile isignali yendawo ye-camshaft.
Ukusebenza kwephutha nomthelela
Uma inzwa ye-camshaft ihluleka, izimpawu ezivamile zihlanganisa ubunzima bokuqala imoto, ubunzima bokugcwalisa amafutha noma ukumisa lapho kushisa, ukwanda kokusetshenziswa kukaphethiloli, amandla anganele kanye nokusheshisa okubi. Lezi zimpawu zidalwa ukungakwazi kwe-ECU ukulawula ngokunembile umjovo kaphethiloli kanye nesikhathi sokubasa.
