Yintoni ivalvu yokulawula iimoto - indibano yokulawula isigaba se-camshaft
I-valve yokulawula iimoto - i-camshaft phase controller assembly yinxalenye ebalulekileyo kwinjini yemoto, enoxanduva lokulawula amaxesha okuvula nokuvala kweevalvu ukuze kuphuculwe ukusebenza kwenjini.
Iingcamango ezisisiseko kunye nemisebenzi
Indibano yesiguquli sesigaba se-camshaft yinxalenye ebalulekileyo yesitimela se-valve senjini. Umsebenzi wayo ophambili kukulungisa amaxesha okuvula nokuvala kwee-valve ukuze zihlangabezane neemfuno zenjini phantsi kweemeko ezahlukeneyo zokusebenza. Ngokukodwa, indibano yesilawulo sesigaba se-camshaft inokulawula ngokuchanekileyo ixesha lokukhupha umoya kunye nokungenisa umoya ngokusekelwe kwisantya senjini kunye neemeko zomthwalo, ngaloo ndlela iphucula amandla enjini, i-torque kunye noqoqosho lwamafutha.
Umgaqo wokusebenza
Umgaqo osebenzayo wendibano ye-camshaft phase converter usekelwe ekulungiseni isigaba se-camshaft ngeendlela ze-hydraulic okanye ze-mechanical. Kwinkqubo ye-hydraulic, iyunithi yokulawula injini (ECU) ilawula utshintsho kuxinzelelo lweoyile ngokusekelwe kulwazi lwempendulo oluvela kwiisensa ezahlukeneyo, ngaloo ndlela itshintsha isigaba se-camshaft. Indlela ye-mechanical ifezekisa uhlengahlengiso lwesigaba ngokusebenzisa izixhobo ze-mechanical ezifana neegiya okanye iitsheyini .
Ulwakhiwo lwesakhiwo
Indibano ye-camshaft phaser idla ngokwenziwa ngala macandelo alandelayo:
I-stator ye-Youdaoplaceholder0 : Inxalenye ezinzileyo, edla ngokudityaniswa nebhloko yenjini.
I-rotor ye-Youdaoplaceholder0 : Inxalenye eshukumayo ehamba ngokuthe ngqo kwi-stator ngeendlela ze-hydraulic okanye ze-mechanical.
I-Youdaoplaceholder0 control oil passage : isetyenziselwa ukukhokela nokulawula uxinzelelo kunye nokuhamba kweoyile ye-hydraulic.
I-Youdaoplaceholder0 actuator : Ngokwemiyalelo ye-ECU, ilawula utshintsho kuxinzelelo lweoyile ukuze ilungise isigaba se-camshaft .
Iimeko zokusetyenziswa kunye nokubaluleka kwazo
Indibano yesiguquli sesigaba se-camshaft idlala indima ebalulekileyo kwiinjini zeemoto. Ingalungisa ngokuzenzekelayo amaxesha okuvula nokuvala kweevalvu ngokweemeko ezahlukeneyo zokusebenza kwenjini (ezifana nokungaqhubi kakuhle, ukukhawulezisa, ukuqhuba ngesantya esiphezulu, njl.njl.), ngaloo ndlela iphucula isantya sempendulo yenjini, ukonga amafutha kunye nokusebenza kokukhupha umbane. Ukongeza, ulawulo oluchanekileyo lwendibano yesiguquli sesigaba se-camshaft lunokwandisa ubomi benkonzo yenjini kwaye lunciphise izinga lokusilela .
Umsebenzi ophambili wevalvu yokulawula iimoto - indibano yokulawula isigaba se-camshaft kukulawula ixesha levalvu yenjini, ngaloo ndlela kuphucula ukusebenza kwenjini.
Iingcamango ezisisiseko kunye nemisebenzi yabalawuli besigaba se-camshaft
Umlawuli wesigaba se-camshaft, okwaziwa ngokuba ngumlawuli we-camshaft okanye umlawuli wesigaba se-camshaft, unomsebenzi ophambili wokuqokelela imiqondiso yendawo ye-valve camshaft kunye nokufaka ezi miqondiso kwiyunithi yolawulo lwe-elektroniki (ECU). Ngale miqondiso, i-ECU inokuchonga iziko elifileyo le-compression top yesilinda 1, ize emva koko yenze ulawulo lwe-fuel injection olulandelelanayo, ulawulo lwexesha lokutsha kunye nolawulo lwe-deflagration. Ukongeza, isignali yendawo ye-camshaft ikwasetyenziselwa ukuchonga umzuzu wokuqala wokutsha xa injini iqala.
Umgaqo wokusebenza we-camshaft phaser
Isilawuli sesigaba se-camshaft sijonga indawo kunye ne-Engela ye-camshaft kwaye sibuyisela isignali kwiyunithi yokulawula injini (ECU) ngexesha langempela ukuqinisekisa ukuba iivalvu ziyavuleka kwaye zivale ngexesha xa i-piston ifikelela kwindawo efanelekileyo. Olu lawulo luchanekileyo luqinisekisa ukuba yonke i-intake kunye ne-exhaust iyafana, ngaloo ndlela iphucula amandla enjini kwaye inciphise ukusetyenziswa kwepetroli.
Ulwakhiwo lwesakhiwo se-camshaft phaser
Xa sithatha inkqubo ye-VANOS njengomzekelo, i-camshaft phase regulator yenziwe kakhulu yi-inner rotor kunye ne-camshaft ezidityaniswe kunye ngama-bolts, kwaye i-timing chain idityaniswe ne-camshaft phase regulator housing. Ngaphakathi kwi-rotor, kukho izipringi kunye nee-blades. Njengoko i-rotor ijikeleza, ii-blades ziqhuba i-camshaft ukuba ijikeleze, ngaloo ndlela zitshintsha i-valve train phase. Xa isantya senjini sitshintsha, i-ECU iya kuthumela imiyalelo kwi-oil control valve ngokusekelwe kwindawo ye-camshaft, kwaye ilawule i-camshaft phase ngokulungelelanisa uxinzelelo lweoyile kumacala omabini egumbi lokusebenza.
