Indima yesenzi sendawo yeCamshaft.
Indima yesixhobo sokuvavanya isikhundla se-camshaft yemoto:
1, i-sensor yesikhundla se-camshaft kukuqokelela isignali ye-Angle eguquguqukayo ye-camshaft, kwaye ifake iyunithi yolawulo lwe-elektroniki (ECU), ukuze kuchongwe ixesha lokutsha kunye nexesha lokujova, ukuze kufumaneke indawo yokungenisa kunye neyokukhupha umoya;
2, ukuze kwenziwe ulawulo lokufaka amafutha ngokulandelelana, ulawulo lwexesha lokutsha kunye nolawulo lokudamba. Ukongeza, isignali yesikhundla se-camshaft isetyenziselwa ukuchonga umzuzu wokuqala wokutsha xa injini iqala. Ngenxa yokuba i-sensor yesikhundla se-camshaft inokuchonga ukuba yeyiphi i-piston yesilinda eza kufikelela kwi-TDC, ibizwa ngokuba yi-sensor yokuchonga isilinda;
3, ulwakhiwo kunye nomgaqo wokusebenza we-camshaft position sensor kunye ne-crankshaft position sensor ziyafana ngokusisiseko, kwaye zihlala zifakelwe kunye, kodwa indawo yokufakela yemodeli nganye yahlukile, kodwa kufuneka ifakwe kwindawo yobudlelwane obuchanekileyo bokudluliselwa kunye ne-crankshaft, njenge-crankshaft, i-camshaft, i-flywheel okanye umsasazi;
4, sebenzisa nje i-crankshaft sensor. Inkqubo ye-ECU inenkqubo ekhethekileyo yokwahlula i-ignition, ukwahlula ulandelelwano lwe-cylinder ignition, yahlukile kwindlela yokusebenzisa ii-sensors ezimbini oko kukuthi, ingongoma ethandwayo yi-"count", i-crankshaft isebenza "1-3-4-2" kwinani elimiselweyo lee-revolutions. Ngoko ke inkqubo ingakwazi "ukubala" ii-cylinders ezahlukeneyo zokudubula kwi-crankshaft Angle efanayo, ngoko ke i-sensor enye yanele.
I-Camshaft position sensor ikwaziwa njenge-cylinder identification sensor, ukuze yahlulwe kwi-crankshaft position sensor (CPS), i-camshaft position sensor imelwa ngokubanzi yi-CIS. Umsebenzi we-camshaft position sensor kukuqokelela isignali yendawo ye-valve camshaft kwaye uyifake kwi-ECU, ukuze i-ECU ikwazi ukubona iziko eliphezulu le-cylinder 1 compression, ukuze yenze ulawulo lwe-fuel injection olulandelelanayo, ulawulo lwexesha lokutsha kunye nolawulo lwe-deflagging. Ukongeza, isignali yendawo ye-camshaft isetyenziselwa ukuchonga umzuzu wokuqala wokutsha xa injini iqala. Ngenxa yokuba i-camshaft position sensor inokuchonga ukuba yeyiphi i-cylinder piston eza kufikelela kwi-TDC, ibizwa ngokuba yi-cylinder identification sensor.
Ukusebenza kakubi kwesensor yeCamshaft
01 Ubunzima bokuqalisa imoto
Ubunzima bokuqalisa imoto bubonakala ngokucacileyo ukuba i-sensor ye-camshaft ayisebenzi kakuhle. I-sensor yendawo ye-camshaft imisela ulandelelwano lokutsha kwenjini. Xa ingaphumeleli, ulandelelwano lokutsha luphuma ecaleni, nto leyo ebangela ukuba injini iqale nzima kwaye ngamanye amaxesha ingaqali konke konke. Le meko ayichaphazeli kuphela ukusebenza kokuqala kwesithuthi, kodwa inokubangela umonakalo omkhulu kwinjini. Ke ngoko, xa kufunyaniswe ukuba imoto kunzima ukuyiqalisa, kufuneka ujonge ukuba i-sensor ye-camshaft isebenza ngokufanelekileyo ngokukhawuleza.
02 Ubuthathaka bokukhawulezisa
Ukungakwazi kwemoto ukukhawulezisa imoto kukubonakalisa umonakalo we-camshaft sensor. Xa i-camshaft sensor ingaphumeleli, i-ECU ayinakukwazi ukubona ngokuchanekileyo utshintsho lwendawo ye-camshaft. Oku kuya kuchaphazela iinkqubo zokungenisa kunye nezokukhupha injini, nto leyo ekhokelela ekunciphiseni ukungenisa kunye nokukhupha inkqubo yokukhupha umoya ekufutshane. Ngenxa yokuba ezi zinto zibalulekileyo zingasebenzi kakuhle, imoto iya kudinwa xa ikhawulezisa, ingakumbi xa isantya singaphantsi kwe-2500 RPM.
03 Ukusetyenziswa kwepetroli okwandisiweyo
Ukwanda kokusetyenziswa kwepetroli kukubonakaliswa okucacileyo kokungasebenzi kakuhle kwesensor ye-camshaft. Xa isensor ye-camshaft inempazamo, inkqubo yepetroli yekhompyutha yesithuthi inokuba yingxaki, nto leyo ebangela ukuba umlomo okanye i-injector itshize ipetroli ingasebenzi kakuhle. Le meko yokujova engalunganga ayinyusi nje kuphela ukusetyenziswa kwepetroli yesithuthi, kodwa inokubangela ukuba isantya senjini singakwazi ukuphucula, kwaye imoto ibonakale ibuthathaka. Ke ngoko, ukuba kufunyenwe ukunyuka okungaqhelekanga kokusetyenziswa kwepetroli yesithuthi, kunokuba luphawu lokuba isensor ye-camshaft inempazamo.
04 Isibane semoto esingenamsebenzi
Isibane semoto sidla ngokuthetha ukuba ii-sensors ezininzi zisenokuba azisebenzi kakuhle. Ingakumbi xa i-sensor yendawo ye-camshaft yonakele, le nto iyabonakala kakhulu. Ii-sensors ze-camshaft zihlala zizi-sensors ze-Hall ezineentambo ezintathu, kuquka iintambo zamandla ze-12v okanye ze-5v, iintambo zesignali kunye neentambo zokulapha. Xa iplagi ikhutshwa kwaye injini iqalisiwe, ukuba akukho mbane wesignali ophumayo phakathi komgca wesignali kunye nomgca osisiseko, oku kudla ngokuthetha ukuba i-sensor yonakele. Kwimeko enjalo, isibane semoto esingasebenziyo sinokukhanya ukukhumbuza umqhubi ukuba enze uhlolo oluneenkcukacha.
05 Umzimba ungcangcazela ngendlela engaqhelekanga
Ukungcangcazela komzimba okungaqhelekanga kukubonakaliswa okucacileyo kokungasebenzi kakuhle kwesensor ye-camshaft. Xa kukho ingxaki ngesensor ye-camshaft, iyunithi yolawulo lwenjini yesithuthi isenokungakwazi ukufunda ngokuchanekileyo imeko yokusebenza kwenjini, nto leyo ebangela ukusebenza kwenjini okungazinzanga kunye nokungcangcazela komzimba okungaqhelekanga. Olu qhushumbo ludla ngokubonakala ngakumbi xa imoto ikhawuleza okanye isiya ngesantya. Ukuqinisekisa ukhuseleko lokuqhuba, xa kufunyenwe iingxaki ezinjalo, kufuneka kwenziwe uhlolo lobuchwephesha kunye nokugcinwa ngexesha.
