Yintoni indima ye-sensor ye-camshaft yemoto
I-sensor yendawo ye-Camshaft idlala indima ebalulekileyo kwinjini yemoto, umsebenzi ophambili kukuqokelela isignali yendawo ye-camshaft kwaye uyifake kwiyunithi yolawulo lwe-elektroniki (ECU) ukuze kuchongwe ixesha lokutsha kunye nexesha lokufaka ipetroli. Ngokubona indawo yokujikeleza kwe-camshaft, i-sensor imisela ixesha lokuvula nelokuvala ivalvu, ngaloo ndlela ifezekisa ulawulo oluchanekileyo lwenjini.
Umgaqo wokusebenza kwe-sensor yesikhundla se-camshaft usekelwe kwi-electromagnetic induction okanye i-photoelectric induction technology. Xa i-camshaft ijikeleza, i-sensor ibona i-bump okanye i-notch kwi-camshaft kwaye ivelise isignali yombane ehambelanayo. Emva kokufumana ezi signals, i-ECU imisela ixesha lokutsha kunye nexesha lokufaka i-fuel ngokubala kunye nokucubungula, ukuze kufezekiswe ulawulo oluchanekileyo lwenjini.
Ukuchaneka nokuthembeka kwee-sensors zesikhundla se-camshaft kubalulekile ekusebenzeni kwenjini kunye nokonga amafutha. Ukuba i-sensor ayisebenzi kakuhle, inokukhokelela ekutshiseni okungachanekanga, ekunciphiseni ukonga amafutha, kwaye mhlawumbi nenjini engasebenzi kakuhle. Ke ngoko, ukuhlolwa rhoqo kunye nokugcinwa kwe-sensor yesikhundla se-camshaft kubaluleke kakhulu.
I-camshaft sensor yinxalenye ebalulekileyo yemoto, esetyenziselwa kakhulu ukubona indawo kunye nesantya se-camshaft, ukuqinisekisa ukusebenza okuqhelekileyo kwenjini. I-Camshaft Sensor, ekwaziwa ngokuba yi-Camshaft Position Sensor (CPS) okanye i-Cylinder Identification Sensor (CIS), umsebenzi wayo ophambili kukuqokelela imiqondiso yendawo ye-valve camshaft. Ezi signals zifakwa kwiYunithi yoLawulo lwe-elektroniki (ECU). Ukusuka kwezi signals, i-ECU iyakwazi ukubona i-TDC yokucinezelwa kwesilinda 1 yolawulo lwe-fuel injection sequentially, ulawulo lwexesha lokutsha kunye nolawulo lwe-deflagration .
Ulwakhiwo kunye nomgaqo wokusebenza
Kukho iintlobo ezininzi zee-sensors ze-camshaft position, kuquka i-photoelectric kunye ne-magnetic induction. I-Photoelectric sensor yenziwe kakhulu yi-signal disk, i-signal generator kunye ne-distributor, kwaye ivelisa i-signal nge-light-emitting diode kunye ne-photosensitive transistor. Uhlobo lwe-magnetic induction lusebenzisa i-Hall effect okanye umgaqo we-magnetic induction ukuvelisa i-signals, ezihlala zahlulwe ngohlobo lwe-Hall kunye nohlobo lwe-magnetoelectric .
Indawo yokufakela
I-sensor yendawo ye-camshaft idla ngokufakwa kwisiphelo esingaphambili sekhava ye-camshaft, ngokuchasene nesiphelo esingaphambili se-camshaft yokungenisa kunye ne-exhaust. Olu yilo luqinisekisa ukuba i-sensor inokuqokelela ngokuchanekileyo isignali yendawo ye-camshaft .
Ukusebenza kwempazamo kunye nempembelelo
Ukuba i-camshaft sensor ayisebenzi, iimpawu eziqhelekileyo ziquka ubunzima bokuqalisa imoto, ubunzima bokugcwalisa ipetroli okanye ukuma xa ishushu, ukusetyenziswa kwepetroli okwandisiweyo, amandla angonelanga kunye nokukhawulezisa okungekho semgangathweni. Ezi mpawu zibangelwa kukungakwazi kwe-ECU ukulawula ngokuchanekileyo ukufakwa kwepetroli kunye nexesha lokutsha.
