Yintoni indima ye-automotive camshaft sensor
I-sensor yesikhundla se-Camshaft idlala indima ebalulekileyo kwi-injini yemoto, umsebenzi ophambili kukuqokelela isignali yendawo ye-camshaft kwaye ifake kwiyunithi yokulawula i-electronic (ECU) ukwenzela ukumisela ixesha lokutshisa kunye nexesha le-injection ye-fuel. Ngokubona indawo yokujikeleza kwe-camshaft, inzwa imisela ixesha lokuvula kunye nokuvala i-valve, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lwe-injini. ...
Umgaqo wokusebenza we-sensor ye-camshaft isikhundla usekwe kwi-electromagnetic induction okanye i-photoelectric induction technology. Xa i-camshaft ijikeleza, inzwa ibona i-bump okanye i-notch kwi-camshaft kwaye ivelise uphawu oluhambelana nombane. Emva kokufumana le miqondiso, i-ECU imisela ixesha lokutshisa kunye nexesha lokutofa kwamafutha ngokubala kunye nokucubungula, ukuze kuphunyezwe ulawulo oluchanekileyo lwe-injini. ...
Ukuchaneka kunye nokuthembeka kwe-camshaft position sensors zibaluleke kakhulu ekusebenzeni kweenjini kunye noqoqosho lwamafutha. Ukuba i-sensor iyasilela, inokukhokelela ekutshiseni okungachanekanga, ukunciphisa uqoqosho lwamafutha, kwaye mhlawumbi nokuba injini engasebenzi kakuhle. Ngoko ke, ukuhlolwa rhoqo kunye nokugcinwa kwe-sensor isikhundla se-camshaft kubaluleke kakhulu.
I-sensor ye-camshaft yinxalenye ebalulekileyo yemoto, isetyenziselwa ukufumanisa indawo ye-camshaft kunye nesantya, ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini. I-Camshaft Sensor, eyaziwa ngokuba yi-Camshaft Position Sensor (CPS) okanye i-Cylinder Identification Sensor (CIS), umsebenzi wayo oyintloko kukuqokelela iimpawu zendawo ye-valve camshaft. Le miqondiso ifakwe kwiYunithi yolawulo lwe-elektroniki (ECU). Ukusuka kule miqondiso, i-ECU iyakwazi ukuchonga i-TDC yokunyanzeliswa kwe-cylinder 1 yokulawulwa kwe-injection ye-fuel ngokulandelelana, ukulawula ixesha lokucima kunye nokulawula ukuchithwa kweflagration.
Ubume kunye nomgaqo wokusebenza
Kukho iintlobo ezininzi ze-camshaft position sensors, kubandakanywa i-photoelectric kunye ne-magnetic induction. Isivamvo sombane wefoto ikakhulu yenziwe ngediski yesiginali, ijenereyitha yesiginali kunye nomsasazi, kwaye ivelisa umqondiso ngokusebenzisa idiode ekhupha ukukhanya kunye ne-photosensitive transistor. Uhlobo lokungeniswa kwamagnetic lusebenzisa isiphumo seHolo okanye umgaqo wokungeniswa kwamagnetic ukuvelisa imiqondiso, edla ngokwahlulahlulwe ibe luhlobo lweHolo kunye nohlobo lwemagnetoelectric.
Indawo yokufakela
I-sensor ye-camshaft ye-sensor ivame ukufakwa kwisiphelo sangaphambili sekhava ye-camshaft, ejongene nesiphelo sangaphambili sokungena kunye nokukhupha i-camshaft. Olu luyilo luqinisekisa ukuba inzwa inokuqokelela ngokuchanekileyo uphawu lwendawo yecamshaft.
Ukusebenza kwempazamo kunye nefuthe
Ukuba i-sensor ye-camshaft ihluleka, iimpawu eziqhelekileyo zibandakanya ubunzima bokuqalisa isithuthi, ubunzima be-refueling okanye ukucima xa kushushu, ukunyuka kokusetyenziswa kwepetroli, amandla anganeleyo kunye nokukhawuleza okungahambi kakuhle. Ezi mpawu zibangelwa kukungakwazi kwe-ECU ukulawula ngokuchanekileyo inaliti yamafutha kunye nexesha lokutshisa.
