Iyini inzwa yendawo ye-camshaft
I-Camshaft Position Sensor (CPS) iyingxenye ebalulekile yezimoto, ikakhulukazi esetshenziselwa ukuqoqa isignali yendawo ye-valve camshaft bese iyifaka ku-electronic control unit (ECU), ukuze i-ECU ikwazi ukuhlonza isikhungo esiphezulu sokucindezelwa kwesilinda 1. Ngakho-ke, ukulawulwa komjovo kaphethiloli okulandelanayo, ukulawula isikhathi sokushisa kanye nokulawula ukwehla.
Incazelo kanye nomsebenzi
I-Camshaft position sensor yaziwa nangokuthi i-cylinder identification sensor (CIS) noma inzwa yesignali yokuvumelanisa, umsebenzi wayo oyinhloko ukuqapha ukunyakaza kwe-camshaft ukuqinisekisa ukusebenza kahle nokusebenza kwenjini. Inzwa izwa ukuguqulwa kwe-camshaft ezindaweni ezihlukene ukuze inikeze amasignali adingekayo okulawulwa kwenjini, ukusekela ukulawula isikhathi, ukulawulwa komjovo kaphethiloli kanye namasu okuphatha i-dedetonation.
Isimiso sokusebenza kanye nohlobo
Isimiso sokusebenza se-camshaft position sensor ngokuvamile sihlanganisa izinhlobo ezimbili: uhlobo lwe-photoelectric kanye nohlobo lokungeniswa kazibuthe:
I-Photoelectric : Ukushintsha kwendawo ye-camshaft kuzwakala ngembobo yokudlulisa ukukhanya kudiski yesignali kanye ne-photosensitive transistor.
Ukungeniswa kukazibuthe : Kusetshenziswa umphumela weHholo noma umgomo wokungeniswa kazibuthe ukuze kutholwe indawo ye-camshaft ngokuzwa ukuguquka kwendawo kazibuthe.
Umthelela wephutha kanye nezindlela zokunakekela
Lapho inzwa yendawo ye-camshaft yehluleka, injini ingase ibonise izinkinga ezinjengobunzima bokuqalisa, isivinini esishintshashintshayo sokungenzi lutho, amandla ancishisiwe, ukusetshenziswa kukaphethiloli okwandisiwe kanye nokuzamazama kwemoto. Ukuze unqume isimo sokusebenza senzwa, ungasebenzisa igiya le-multimeter diode ukuze uthole incazelo yephinikhodi yayo.
Lapho inzwa ye-camshaft isikhundla iphukile, izoba nomthelela omubi ekusebenzeni kwemoto ezicini eziningi, kanje:
Ubunzima bokushisa : Inzwa yesikhundla se-camshaft inesibopho sokuhlinzeka ngesignali yendawo ye-camshaft ku-electronic control Unit (ECU) ukuze kunqunywe isikhathi sokuthungela. Uma inzwa yonakele, i-ECU ayikwazi ukuthola amasignali esikhundla esinembile, okungase kuholele ekushiseni okungalungile kanye nobunzima ekuqaliseni injini.
ukusebenza kwenjini okuncishisiwe : Ukwehluleka kwezinzwa kungase kuthinte ukusebenza kwenjini ngokuvimbela ukulawulwa okunembile komjovo kaphethiloli nesikhathi sokubasa. Kungase kube nokuntuleka kokusheshisa, ukwehla kwamandla nezinye izimo.
ukwanda kokusetshenziswa kukaphethiloli : Njengoba inzwa ingakwazi ukubona ngokunembile indawo ye-camshaft, ukusebenza kwenjini kungase kuchezuke esimweni esifanele, kubangele ukusha kukaphethiloli okwanele kanye nokwanda kokusetshenziswa kukaphethiloli.
ukungcola okwedlulele : ukushiswa komlilo okwanele ngeke nje kukhulise ukusetshenziswa kukaphethiloli, kodwa futhi kuzoholela ekwenyukeni kwezinto eziyingozi eziphuma kusisi, ezingase zingcolise imvelo futhi zibe nomthelela ekuhlolweni kwemoto edlulayo.
Ukusebenza kwenjini engalingani : Ukwehluleka kwezinzwa kungase kubangele injini ukuba idlidlize noma ime lapho ingenzi lutho, kuphazamise umuzwa wokushayela.
Isibani esinephutha lenjini sivuliwe : Uma uhlelo lokuzihlolela imoto luthola ukuthi kunenkinga ngenzwa yokuma kwe-camshaft, ukukhanya kwenjini kuzokhanya ukuze kukhumbuze umnikazi ukuthi ahlole futhi alungise kusenesikhathi.
Ngakho-ke, uma inzwa yesikhundla se-camshaft itholakala ukuthi inenkinga, kunconywa ukuthi uye ngokushesha esitolo sokukhanda esichwepheshe ukuze sihlolwe futhi sifakwe esikhundleni sokuqinisekisa ukusebenza okuvamile kwemoto nokuphepha kokushayela.
