Yintoni inzwa yendawo yecamshaft
I-Camshaft Position Sensor (CPS) yinxalenye ebalulekileyo yeemoto, ngokukodwa isetyenziselwa ukuqokelela isignali yendawo ye-valve camshaft kwaye ifake kwiyunithi yokulawula i-electronic control unit (ECU), ukwenzela ukuba i-ECU ikwazi ukuchonga i-compression top center ye-cylinder 1. Ngaloo ndlela, ukulawulwa kwe-injection ye-fuel sequential, ulawulo lwexesha lokutshisa kunye nokulawula ukuchithwa.
Inkcazo kunye nomsebenzi
I-sensor yesikhundla seCamshaft yaziwa nangokuthi i-cylinder identification sensor (CIS) okanye i-sensor yesignali yokuvumelanisa, umsebenzi wayo oyintloko kukubeka iliso kwintshukumo ye-camshaft ukuqinisekisa ukusebenza kakuhle kunye nokusebenza kwe-injini. I-sensor ibona utshintsho lwecamshaft kwiindawo ezahlukeneyo ukubonelela ngemiqondiso eyimfuneko yolawulo lwe-injini, ukuxhasa ulawulo lwexesha, ukulawulwa kwenaliti yamafutha kunye nezicwangciso zolawulo lwe-dedetonation.
Umgaqo wokusebenza kunye nohlobo
Umgaqo wokusebenza we-camshaft position sensor udla ngokubandakanya iindidi ezimbini: uhlobo lwefotoelectric kunye nohlobo lokungeniswa kwamagnetic:
I-Photoelectric : Ukutshintsha kwesikhundla se-camshaft kubonwa ngomngxuma wokuhambisa ukukhanya kwidiski yesignali kunye ne-photosensitive transistor.
Ukwenziwa kwemagnethi : Ukusebenzisa isiphumo seHolo okanye umgaqo wokungeniswa kwemagnethi ukubona indawo ekuyo icamshaft ngokuva utshintsho lwemagnethi.
Impembelelo yempazamo kunye neendlela zokulondoloza
Xa i-sensor yendawo ye-camshaft ingaphumeleli, i-injini inokubonisa iingxaki ezinjengokuqala kobunzima, isantya esingenamsebenzi esingaqhelekanga, ukunciphisa amandla, ukwanda kokusetyenziswa kwepetroli kunye nokushukuma kwemoto. Ukumisela ubume bokusebenza kwenzwa, ungasebenzisa i-multimeter diode gear ukubona inkcazo yepini yayo.
Xa i-sensor ye-camshaft iphukile, iya kuba nefuthe elibi ekusebenzeni kwemoto kwiinkalo ezininzi, ngolu hlobo lulandelayo:
Ubunzima bomlilo : I-sensor yendawo ye-camshaft inoxanduva lokubonelela ngesignali yendawo ye-camshaft kwiYunithi yokulawula i-elektroniki (ECU) ukujonga ixesha lokucima. Ukuba i-sensor yonakalisiwe, i-ECU ayikwazi ukufumana iimpawu ezichanekileyo zendawo, ezinokukhokelela ekutshiseni okungachanekanga kunye nobunzima bokuqalisa injini.
ukusebenza kwe-injini okucuthiweyo : Ukusilela kwenzwa kunokuchaphazela ukusebenza kwe-injini ngokuthintela ulawulo oluchanekileyo lwenaliti yamafutha kunye nexesha lokutshisa. Kunokubakho ukunqongophala kokukhawuleza, ukuhla kwamandla kunye nezinye iimeko.
ukwanda kokusetyenziswa kwepetroli : Ekubeni inzwa ayinakukwazi ukubona ngokuchanekileyo indawo yecamshaft, ukusebenza kwe-injini kunokuphambuka kwimeko efanelekileyo, kubangele ukutshiswa kwepetroli okungonelanga kunye nokunyuka kokusetyenziswa kwepetroli.
ukukhutshwa okugqithisileyo : ukutshisa okungafanelekanga akuyi kwandisa kuphela ukusetyenziswa kwepetroli, kodwa kuya kukhokelela ekwandeni kwezinto ezinobungozi kukukhutshwa kombhobho, okunokuthi kungcolise okusingqongileyo kwaye kuchaphazele uvavanyo lokukhutshwa kwesithuthi.
Ukusebenza kwe-injini engalinganiyo: Ukusilela kwenzwa kunokubangela ukuba injini ingcangcazele okanye ime ngokungenzi nto, okuchaphazela amava okuqhuba.
Isibane sempazamo ye-injini : Xa inkqubo yokuhlola isithuthi ifumanisa ukuba kukho ingxaki nge-sensor ye-camshaft, ukukhanya kwe-injini kuya kukhanya ukukhumbuza umnini ukuba ajonge kwaye alungise ngexesha.
Ngoko ke, emva kokuba i-sensor ye-camshaft ifunyenwe ukuba inengxaki, kuyacetyiswa ukuba uye ngokukhawuleza kwivenkile yokulungisa i-professional ukuze ihlolwe kunye nokutshintshwa ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwemoto kunye nokhuseleko lokuqhuba.
