Iyini inzwa yesikhundla se-camshaft
I-Camshaft Position Sensor (CPS) iyisici esibalulekile sezimoto, esisetshenziswa kakhulu ukuqoqa isignali yesikhundla se-valve camshaft bese siyifaka kuyunithi yokulawula kagesi (ECU), ukuze i-ECU ikwazi ukubona isikhungo esiphezulu sokucindezela sesilinda 1. Ngakho-ke, ukulawula okulandelanayo kokujova uphethiloli, ukulawula isikhathi sokusha kanye nokulawula ukucisha ugesi.
Incazelo kanye nomsebenzi
Inzwa yesikhundla se-Camshaft yaziwa nangokuthi inzwa yokuhlonza isilinda (i-CIS) noma inzwa yesignali yokuvumelanisa, umsebenzi wayo oyinhloko ukuqapha ukunyakaza kwe-camshaft ukuqinisekisa ukusebenza kahle nokusebenza kwenjini. Inzwa izwa ushintsho lwe-camshaft ezindaweni ezahlukene ukuze inikeze izimpawu ezidingekayo zokuphathwa kwenjini, ukusekela ukulawula isikhathi, ukulawula ukujova uphethiloli kanye namasu okuphatha ukudilika kwe-ion.
Isimiso sokusebenza kanye nohlobo
Isimiso sokusebenza senzwa yesikhundla se-camshaft sivame ukufaka izinhlobo ezimbili: uhlobo lwe-photoelectric kanye nohlobo lwe-magnetic induction:
I-Photoelectric : Ukushintsha kwesimo se-camshaft kuzwakala ngembobo yokudlulisa ukukhanya kudiski yesiginali kanye ne-transistor ezwela ukukhanya.
Ukufakwa kwe-magnetic: Ukusebenzisa umphumela we-Hall noma isimiso sokufakwa kwe-magnetic ukuthola indawo ye-camshaft ngokuzwa ushintsho lwensimu yamagnetic.
Izindlela zomthelela wamaphutha kanye nokulungisa
Uma inzwa yesikhundla se-camshaft ihluleka, injini ingase ibonise izinkinga ezifana nobunzima bokuqala, isivinini esingaguquki sokusebenza, amandla ancishisiwe, ukusetshenziswa kukaphethiloli okwandisiwe kanye nokuzamazama kwemoto. Ukuze unqume isimo sokusebenza senzwa, ungasebenzisa igiya le-diode le-multimeter ukuthola incazelo yephinikhodi yayo.
Uma inzwa yesikhundla se-camshaft iphukile, izoba nomthelela omubi ekusebenzeni kwemoto ezicini eziningi, kanje:
Ubunzima bokuvutha : Inzwa yesikhundla se-camshaft inesibopho sokuhlinzeka ngesignali yesikhundla se-camshaft kwi-electronic control Unit (ECU) ukuze inqume isikhathi sokuvutha. Uma inzwa yonakele, i-ECU ayikwazi ukuthola izimpawu zesikhundla ezinembile, okungaholela ekuvutheni okungafanele kanye nobunzima bokuqalisa injini.
ukusebenza kwenjini okuncishisiwe : Ukwehluleka kwezinzwa kungathinta ukusebenza kwenjini ngokuvimbela ukulawulwa okunembile kokujova uphethiloli kanye nesikhathi sokusha. Kungase kube nokuntuleka kokusheshisa, ukwehla kwamandla nezinye izimo.
ukusetshenziswa kukaphethiloli okwandisiwe : Njengoba inzwa ingakwazi ukubona ngokunembile indawo ye-camshaft, ukusebenza kwenjini kungase kuphambuke esimweni esifanele, okuholela ekushiseni kukaphethiloli okunganele kanye nokusetshenziswa kukaphethiloli okwandisiwe.
Ukweqa ukukhishwa kwegesi: ukusha okunganele ngeke nje kwandise ukusetshenziswa kukaphethiloli, kodwa futhi kuzoholela ekwandeni kwezinto eziyingozi ekukhishweni kwegesi, okungangcolisa imvelo futhi kuthinte ukuhlolwa kokukhishwa kwegesi emotweni.
Ukusebenza kwenjini okungalingani: Ukwehluleka kwenzwa kungabangela ukuthi injini idlidlize noma ime lapho ingasebenzi, okuthinta ulwazi lokushayela.
Isibani sephutha lenjini sivuliwe: Uma uhlelo lokuzihlola lwemoto luthola ukuthi kunenkinga ngenzwa yesikhundla se-camshaft, isibani sephutha lenjini sizokhanya ukukhumbuza umnikazi ukuthi ahlole futhi alungise ngesikhathi.
Ngakho-ke, uma inzwa yesikhundla se-camshaft itholakale inenkinga, kunconywa ukuthi uye ngokushesha esitolo sokulungisa sochwepheshe ukuze uhlolwe futhi ushintshwe ukuqinisekisa ukusebenza okuvamile kwemoto nokuphepha kokushayela.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
