Yintoni inzwa yendawo ye-camshaft
I-Camshaft Position Sensor (CPS) yinxalenye ebalulekileyo yeemoto, esetyenziselwa ukuqokelela isignali yendawo ye-valve camshaft kwaye iyifake kwiyunithi yolawulo lwe-elektroniki (ECU), ukuze i-ECU ikwazi ukubona iziko eliphezulu lokucinezelwa kwesilinda 1. Ke ngoko, ulawulo lwe-fuel injection olulandelelanayo, ulawulo lwexesha lokutsha kunye nolawulo lwe-deflagration .
Inkcazo kunye nomsebenzi
I-Camshaft position sensor ikwaziwa ngokuba yi-cylinder identification sensor (CIS) okanye i-synchronization signal sensor, umsebenzi wayo ophambili kukujonga intshukumo ye-camshaft ukuqinisekisa ukusebenza kakuhle kunye nokusebenza kwenjini. I-sensor iyaziva utshintsho lwe-camshaft kwiindawo ezahlukeneyo ukuze ibonelele ngemiqondiso efunekayo yolawulo lwenjini, ukuxhasa ulawulo lwexesha, ulawulo lokujova ipetroli kunye namaqhinga olawulo lokudilika kwe-ion.
Umgaqo wokusebenza kunye nohlobo
Umgaqo wokusebenza we-sensor yesikhundla se-camshaft udla ngokubandakanya iintlobo ezimbini: uhlobo lwe-photoelectric kunye nohlobo lwe-magnetic induction:
I-Photoelectric : Utshintsho lwendawo ye-camshaft luvakala ngomngxuma wokudlulisa ukukhanya kwidiski yesignali kunye ne-transistor ebona ukukhanya.
Ukufakelwa kwemagnethi: Ukusebenzisa isiphumo seHall okanye umgaqo wokufakelwa kwemagnethi ukubona indawo ye-camshaft ngokuva utshintsho lwentsimi yemagnethi.
Impembelelo yempazamo kunye neendlela zokulungisa
Xa isenzi sendawo ye-camshaft singaphumeleli, injini inokubonisa iingxaki ezifana nobunzima bokuqalisa, isantya esingaguqukiyo sokungaqhubi kakuhle, amandla anciphileyo, ukusetyenziswa kwepetroli okwandisiweyo kunye nokushukuma kwesithuthi. Ukuze ufumane imeko yokusebenza yesenzi, ungasebenzisa igiya ye-diode ye-multimeter ukuze ubone inkcazo yephini yayo.
Xa isenzi sendawo ye-camshaft siphukile, siya kuba nefuthe elibi ekusebenzeni kwemoto kwiinkalo ezininzi, ngolu hlobo lulandelayo:
Ubunzima bokutsha: I-sensor yendawo ye-camshaft inoxanduva lokubonelela ngesignali yendawo ye-camshaft kwiYunithi yoLawulo lwe-elektroniki (ECU) ukuze imisele ixesha lokutsha. Ukuba i-sensor yonakele, i-ECU ayinakufumana imiqondiso echanekileyo yendawo, nto leyo enokukhokelela ekutshayweni okungachanekanga kunye nobunzima ekuqaliseni injini.
Ukusebenza kwenjini okunciphileyo: Ukungasebenzi kakuhle kwezixhobo zokubona kunokuchaphazela ukusebenza kwenjini ngokuthintela ulawulo oluchanekileyo lokufakwa kwepetroli kunye nexesha lokutsha. Kusenokubakho ukungabikho kokukhawulezisa, ukwehla kwamandla kunye nezinye iimeko.
ukusetyenziswa kwepetroli okwandisiweyo: Ekubeni i-sensor ingenakukwazi ukubona ngokuchanekileyo indawo ye-camshaft, ukusebenza kwenjini kunokuphambuka kwimeko efanelekileyo, nto leyo ekhokelela ekutshisweni kwepetroli okwaneleyo kunye nokusetyenziswa kwepetroli okwandisiweyo.
Ukugqithisa ukukhutshwa komoya: ukutsha okunganelanga akuyi kwandisa ukusetyenziswa kwepetroli kuphela, kodwa kukwakhokelela ekwandeni kwezinto eziyingozi kwimveliso yokukhupha umoya, ezinokungcolisa okusingqongileyo kwaye zichaphazele uvavanyo lokukhupha umoya oludlulayo kwisithuthi.
Ukusebenza kwenjini okungalinganiyo: Ukungasebenzi kakuhle kwesensor kunokubangela ukuba injini ingcangcazele okanye ime xa ingasebenzi, nto leyo echaphazela amava okuqhuba.
Isibane sempazamo yenjini sivuliwe: Xa inkqubo yokuzixilonga yesithuthi ifumanisa ukuba kukho ingxaki kwisenzi sendawo ye-camshaft, isibane sempazamo yenjini siya kukhanya ukukhumbuza umnini ukuba ajonge aze alungise kwangethuba.
Ngoko ke, xa i-sensor yendawo ye-camshaft ifunyenwe inengxaki, kuyacetyiswa ukuba uye kwangoko kwindawo yokulungisa yobuchwephesha ukuze ihlolwe kwaye itshintshwe ukuqinisekisa ukusebenza okuqhelekileyo kwemoto kunye nokhuseleko lokuqhuba.
