Yintoni ivili lesignali ye-crankshaft yemoto
Ivili lesignali ye-crankshaft yemoto , ekwaziwa ngokuba yi-crankshaft position sensor okanye i-injini speed sensor, umsebenzi walo ophambili kukujonga isantya se-crankshaft kunye ne-engile yenjini, ukuze kuchongwe ngokuchanekileyo indawo ye-crankshaft. Idatha eqokelelweyo idluliselwa kwiYunithi yoLawulo lweNjini (ECU) okanye kwezinye iinkqubo zekhompyutha ezifanelekileyo ukuqinisekisa ulawulo oluchanekileyo lwexesha lokutsha kwenjini .
Umgaqo wokusebenza
Ivili lesignali ye-crankshaft lidla ngokuyilwa njengevili elinamacandelo amaninzi amazinyo. Xa ivili lesignali lidlula kwi-sensor, kwenziwa i-voltage ye-AC, kwaye i-frequency yale voltage iyatshintshatshintsha ngokutshintsha kwesantya. Olu yilo luvumela i-sensor ukuba ilinganise isantya senjini ngokusebenzisa isignali ye-pulse.
Uhlobo kunye nendawo yokufakela
Ivili lesignali yeCrankshaft ngokwemigaqo yokuvelisa imiqondiso linokwahlulwa lube loluhlobo lwe-magnetic induction, uhlobo lwe-photoelectric kunye nohlobo lweHall iintlobo ezintathu. Ii-Common Hall sensors zihlala zamkela uyilo lweengcingo ezi-3, kubandakanya intambo yamandla, intambo yesignali ye-AC kunye nentambo yokukhusela isignali ye-AC. Indawo yokufakela idla ngokuba kumthengisi, kwi-transmission clutch housing, ngaphambili okanye ngasemva kwe-crankshaft, njl.njl., kuxhomekeke kuhlobo lwe-sensor kunye noyilo lwenjini.
Sebenza kunye nezinye izinto
Ivili lesignali ye-crankshaft lidla ngokusebenza kunye ne-sensor yendawo ye-camshaft ukumisela ixesha elisisiseko lokutsha. Ngokubonelela ngolwazi oluchanekileyo lwendawo, baqinisekisa ukuba injini inokusebenza ngokuhambelana nolandelelwano lokudubula olumiselweyo, ngaloo ndlela befezekisa ukusebenza okutyibilikayo nokusebenzayo.
Umsebenzi ophambili wevili lesignali ye-crankshaft yemoto kukubona isantya se-crankshaft kunye ne-engile yenjini, ukumisela indawo ye-crankshaft, kunye nokudlulisela iziphumo ezifunyenweyo kwiyunithi yolawulo lwenjini (ECU) okanye kwezinye iinkqubo zekhompyutha ezifanelekileyo ukuqinisekisa ulawulo oluchanekileyo lwexesha lokutsha kwenjini.
Ngokukodwa, ivili lesignali ye-crankshaft (ekwaziwa ngokuba yi-crankshaft position sensor okanye i-engine speed sensor) linemisebenzi elandelayo:
Jonga isantya senjini: Chonga imeko yokusebenza kwenjini ngokubona isantya se-crankshaft.
Misela indawo ye-TDC yepiston: Chonga indawo ye-TDC yepiston nganye yesilinda. Oku kubalulekile ekulawuleni ukutsha kunye nexesha lokujova ipetroli. Umzekelo, iyakwazi ukubonelela ngemiqondiso ye-TDC yesilinda nganye yokulawula ukutsha kunye nemiqondiso ye-TDC yesilinda yokuqala yokulawula ukujova ipetroli ngokulandelelana.
Ibonelela ngesignali ye-crankshaft Angle: Ngokubona i-crankshaft Angle, qinisekisa ukuba ixesha lokutsha kwenjini kunye nexesha lokufaka ipetroli lichanekile.
Isebenza nge-camshaft position sensor : Ihlala isebenza ne-camshaft position sensor ukuqinisekisa ukuba i-basic stem yokutsha yenjini ichanekile. I-camshaft position sensor imisela ukuba yeyiphi i-cylinder piston ekuxinzelelo, ngelixa i-crankshaft position sensor imisela ukuba yeyiphi i-cylinder piston eku-TDC .
Ukongeza, iimpawu zoyilo lwevili lesignali ye-crankshaft ziquka ivili elinamacandelo amaninzi amazinyo. Xa ivili lesignali lidlula kwi-sensor, kwenziwa i-voltage ye-AC etshintsha rhoqo ngokwesantya.
