Yintoni eyenziwa yi-crankshaft sensor emotweni
Indima ye-sensor ye-crankshaft yemoto kwimoto ibandakanya ikakhulu ezi zinto zilandelayo:
Ulawulo lweXesha lokutsha: Izinzwa zendawo yeCrankshaft zijonga indawo yokujikeleza kwecrankshaft kwaye zibonelela ngedatha ebalulekileyo kwiYunithi yoLawulo lwenjini (ECU) ukunceda ekumiseleni ixesha elifanelekileyo lokudubula kwisilinda nganye. Oku kuqinisekisa ukuba iplagi yespark iyatsha xa ipiston ifika kwi-TDC kwaye umxube ucinezelwe kwisimo sawo esifanelekileyo, ngaloo ndlela kufezekiswa ukutsha kwepetroli okusebenzayo kunye nokuphucula amandla enjini kunye nokonga.
Ulawulo lokujova ipetroli: I-sensor yendawo ye-crankshaft ikwasetyenziselwa ukulawula inkqubo yokujova ipetroli, ukuqinisekisa ukuba ipetroli ikhutshwa ngexesha elifanelekileyo ukuhlangabezana neemfuno zenjini. Ngokujonga indawo ye-crankshaft, inkqubo inokulawula ngokuchanekileyo ubungakanani bojova ipetroli ukuqinisekisa iziphumo ezilungileyo zokutsha phantsi kweemeko ezahlukeneyo zokusebenza.
Ukuqala nokusebenza kwenjini: Ngexesha lokuqalisa injini, i-sensor yendawo ye-crankshaft iqinisekisa ukuba injini iqala ngexesha elifanelekileyo kwaye igcina ukusebenza okuzinzileyo. Ukongeza, ibandakanyeka kulawulo lwesantya sokungaqhubi kakuhle kunye nolawulo lokuphuma kwepetroli, inceda i-ECU ukuba ilungelelanise ukuvulwa kwe-throttle okanye indawo ye-actuator yokungaqhubi kakuhle ukugcina isantya senjini sokungaqhubi kakuhle esizinzileyo.
Ukuba i-sensor yendawo ye-crankshaft iyasilela, inkqubo yolawulo lwe-elektroniki yesithuthi ingafumanisa kwaye ibonise ingxaki ngokufunda ikhowudi yempazamo, incedise ekuxilongweni nasekulungisweni kweengcali.
I-sensor yendawo ye-crankshaft isebenza ukubonelela ngedatha ebalulekileyo kwinkqubo yolawulo lwenjini ngokulinganisa ngokuchanekileyo kunye nokuxela indawo kunye nesantya se-crankshaft. Ifumanisa kwaye ikhuphe imiqondiso ye-stop point, imiqondiso ye-crankshaft Angle, kunye nemiqondiso yesantya senjini, ezifakwa kwi-ECU ngexesha langempela, apho i-ECU ibala ixesha elifanelekileyo lokudubula kunye nomthamo wokufakwa kwepetroli kwisilinda nganye.
Iisensa ze-crankshaft zeemoto (CPS okanye CKP) zidlala indima ebalulekileyo kwiimoto. Yenye yezona sensa zibalulekileyo kwinkqubo yokulawula injini, kwaye imisebenzi yayo ephambili ibandakanya:
Isantya senjini: I-sensor ye-crankshaft inokujonga isantya sokujikeleza kwe-crankshaft ngexesha langempela, ukuze ikwazi ukubala ngokuchanekileyo isantya senjini. Olu lwazi lubaluleke kakhulu ekumiseleni izinga lokufakwa kwepetroli kunye ne-Angle yokuqhubela phambili kwe-ignition.
Misela indawo yepiston: Ngokubona i-engile yokujikeleza kwe-crankshaft, i-crankshaft sensor inokumisela indawo ethile yepiston kwisilinda. Oku kubalulekile ukulawula ixesha lokutsha kunye nokufakwa kwepetroli.
Ukujonga imeko yokusebenza kwenjini: inokujonga imeko yokusebenza kwenjini, xa ifunyenwe njengomlilo okanye ukungabikho komlilo kunye nezinye iziphene, iya kubamba ngokukhawuleza isignali engaqhelekanga, kwaye ifike ngexesha elifanelekileyo kwiyunithi yolawulo lwenjini ukuze ithumele ulwazi lwesilumkiso.
Yenza ngcono ukusebenza kakuhle kokukhupha umbane: Ngokulawula ngokuchanekileyo indawo ye-crankshaft, inkqubo yokutsha kwamafutha inokulungiswa, ukukhutshwa kwezinto ezinobungozi kunokunciphisa, kunye nokusebenza kakuhle kokukhupha umbane kwisithuthi.
Eminye imisebenzi: Ukongeza ekulawuleni ukufakwa kwepetroli kunye nokutsha, i-crankshaft sensor ikwathatha inxaxheba kulawulo lwesantya olungasebenziyo, ulawulo lokujikeleza kwegesi yokukhupha, kunye nolawulo lokuphuma kwepetroli.
Uhlobo kunye nendawo yokufakela
Kukho iintlobo ezimbini eziphambili zee-crankshaft sensors: uhlobo lwe-magnetic pulse kunye nohlobo lweHall. Ii-magnetic pulse sensors zihlala zifakelwa kufutshane ne-transmission housing ye-flywheel, ngelixa ii-Hall sensors zifakelwa ecaleni kwe-crankshaft pulley ngaphambili kwe-crankshaft okanye kwi-transmission housing ecaleni kwe-flywheel. Indawo echanekileyo yokufakela iya kwahluka ngokuxhomekeke kwimodeli kunye noyilo.
