Indima yesivamvo sesikhundla seCamshaft.
Indima ye-automotive camshaft sensor sensor:
I-1, i-sensor ye-camshaft ye-sensor kukuqokelela i-camshaft ye-Angle yesiginali ye-Angle, kwaye ifake iyunithi yokulawula i-electronic (ECU), ukwenzela ukugqiba ixesha lokutshisa kunye nexesha lokujova, ngoko ke ukungena kunye nokukhupha kufumaneka;
2, ukuze kuqhutywe ngokulandelelanayo ulawulo lwenaliti yamafutha, ulawulo lwexesha lokutshisa kunye nolawulo lokutshatyalaliswa kweflagration. Ukongeza, uphawu lwendawo yecamshaft lusetyenziselwa ukuchonga umzuzu wokuqala wokutshisa xa injini iqala. Ngenxa yokuba i-sensor yendawo ye-camshaft inokuchonga ukuba yeyiphi i-cylinder piston malunga nokufikelela kwi-TDC, ibizwa ngokuba yinzwa yokuchongwa kwe-cylinder;
I-3, isakhiwo kunye nomgaqo wokusebenza we-camshaft position sensor kunye ne-crankshaft position sensor ziyafana, kwaye zihlala zifakwe kunye, kodwa indawo yofakelo yemodeli nganye yahlukile, kodwa kufuneka ifakwe kwindawo yobudlelwane obuchanekileyo kunye i-crankshaft, njenge-crankshaft, i-camshaft, i-flywheel okanye i-distributor;
I-4, sebenzisa nje inkqubo ye-ECU ye-crankshaft sensor inenkqubo ekhethekileyo yokwahlula ukuvutha, ukwahlula ulandelelwano lokutshisa i-cylinder, yahlukile kwindlela yokusebenzisa abenzi boluvo ababini, oko kukuthi, indawo ethandwayo "kubala", i-crankshaft. iqhuba "1-3-4-2" kwinani elimiselweyo lohlaziyo. Ke inkqubo inoku "bala" iisilinda zokudubula ezahlukeneyo kwi-crankshaft Angle enye, ngoko ke inzwa enye yanele.
I-sensor yesikhundla seCamshaft yaziwa ngokuba yinzwa yokuchongwa kwe-cylinder, ukwenzela ukwahlula kwi-sensor ye-crankshaft (CPS), i-sensor yendawo ye-camshaft imelwe ngokubanzi yi-CIS. Umsebenzi we-sensor ye-camshaft kukuqokelela umqondiso wesigxina se-valve camshaft kwaye uyifake kwi-ECU, ukwenzela ukuba i-ECU ikwazi ukuchonga iziko eliphezulu lokunyanzeliswa kwe-cylinder 1, ukwenzela ukuba kuqhutywe ukulawulwa kwe-injection ye-fuel ngokulandelelana, ixesha lokutshisa. ulawulo kunye nolawulo lokuthoba iflegi. Ukongeza, uphawu lwendawo yecamshaft lusetyenziselwa ukuchonga umzuzu wokuqala wokutshisa xa injini iqala. Ngenxa yokuba i-sensor yendawo ye-camshaft inokuchonga ukuba yeyiphi i-cylinder piston eza kufikelela kwi-TDC, ibizwa ngokuba yi-cylinder identification sensor.
Umsebenzi ombi woluvo lweCamshaft
01 Ubunzima ekuqaliseni isithuthi
Ubunzima bokuqalisa isithuthi kubonakaliso olucacileyo lwephutha le-sensor ye-camshaft. I-sensor yendawo ye-camshaft imisela ukulandelelana kokuvutha kwe-injini. Xa ingaphumeleli, ulandelelwano lokutshisa luyaphuma kucwangco, lubangela ukuba injini iqale ngobunzima kwaye ngamanye amaxesha ingaqalisi kwaphela. Le meko ayichaphazeli kuphela ukusebenza kokuqala kwesithuthi, kodwa kunokubangela umonakalo ongakumbi kwi-injini. Ngoko ke, xa kufunyenwe ukuba isithuthi kunzima ukuqala, kufuneka ukhangele ukuba i-sensor ye-camshaft isebenza ngokufanelekileyo ngokukhawuleza.
02 Ukukhawuleza ubuthathaka
Ukungakwazi kwemoto ukukhawuleza kukubonakaliswa okucacileyo komonakalo wenzwa ye-camshaft. Xa i-sensor ye-camshaft ihluleka, i-ECU ayikwazi ukubona ngokuchanekileyo utshintsho lwesikhundla se-camshaft. Oku kuya kuchaphazela iinkqubo zokungenisa kunye nokukhupha i-injini, okukhokelela ekunciphiseni ukungenisa kunye nokuphuma kwenkqubo ekufutshane yokukhupha. Ngenxa yokuba la macandelo abalulekileyo angasebenzi kakuhle, imoto iya kuba nokukhathala xa ikhawuleza, ngakumbi xa isantya singaphantsi kwe-2500 RPM.
03 Ukonyuka kokusetyenziswa kwamafutha
Ukunyuka kokusetyenziswa kwamafutha kukubonakaliswa okucacileyo kokungaphumeleli kwe-sensor ye-camshaft. Xa i-sensor ye-camshaft iphosakele, inkqubo ye-fuel ye-computer yesithuthi inokuphazamiseka, ibangele umlomo okanye i-injector itshize amafutha ngaphandle komyalelo. Le meko yokutofa iphazamisekile ayinyusi kuphela ukusetyenziswa kwamafutha esithuthi, kodwa inokubangela ukuba isantya se-injini singakwazi ukuphucula, kwaye isithuthi sibonakala sibuthathaka. Ngoko ke, ukuba ukunyuka okungaqhelekanga kokusetyenziswa kwamafutha esithuthi kufunyenwe, kunokuba ngumqondiso wokuba i-sensor ye-camshaft iphosakele.
04 Isibane seempazamo zemoto
Isibane esinempazamo yesithuthi sihlala sithetha ukuba abenzi boluvo abaninzi banokungasebenzi kakuhle. Ngokukodwa xa i-sensor ye-camshaft isikhundla yonakalisiwe, le nto ibonakala ngokucacileyo. I-Camshaft sensors idla ngokuba yi-3-wire Hall sensors, kuquka i-12v okanye i-5v iintambo zamandla, iintambo zesignali kunye neentambo zokuqhawula. Xa iplagi ikhutshwe kwaye injini iqalisiwe, ukuba akukho mveliso yombane wesignali phakathi komgca wesignali kunye nomgca wesiseko, oku ngokuqhelekileyo kuthetha ukuba inzwa yonakele. Kule meko, isibane sokusilela kwesithuthi sinokufika ukuze sikhumbuze umqhubi ukuba enze uhlolo oluneenkcukacha.
05 Umzimba ungcangcazela ngokungaqhelekanga
Ukungcangcazela komzimba okungaqhelekanga kukubonakaliswa okucacileyo kokungaphumeleli kwe-sensor ye-camshaft. Xa kukho ingxaki nge-sensor ye-camshaft, iyunithi yokulawula injini yesithuthi ayinakukwazi ukufunda ngokuchanekileyo imeko yokusebenza ye-injini, okukhokelela ekusebenzeni kwe-injini engazinzanga kunye nokungcangcazela komzimba okungaqhelekanga. Le jita idla ngokuvakala ngakumbi xa isithuthi sihamba ngesantya okanye sihla. Ukuze kuqinisekiswe ukhuseleko lokuqhuba, zakuba zifunyenwe iingxaki ezinjalo, uhlolo lobuchule nololongo kufuneka lwenziwe kwangethuba.
