Yintoni ivalve yokulawula ioyile yemoto
Ivalve yokulawula ioyile yeemoto (ivalve ye-OCV) yinxalenye ephambili yenkqubo yokuthambisa i-injini, ikakhulu isetyenziselwa ukulawula ngokuchanekileyo isigaba sevalve ye-injini kunye noxinzelelo lwe-oyile, ukuze kuphuculwe ukusebenza kwe-injini kunye noqoqosho lwamafutha.
Inkcazo kunye nomsebenzi
I-valve yokulawula i-oyile (i-valve ye-OCV) iqulethwe ngumzimba we-valve (kubandakanya i-coil ye-solenoid kunye ne-control module connector), i-valve yesilayidi kunye ne-spring yokubuya. Umgaqo osebenzayo kukulawula amandla kunye nokucinywa kwekhoyili ye-electromagnetic ngokusebenzisa umqondiso wokumodareyitha kwepulse obonelelwe yiyunithi yolawulo lwe-injini (ECU), kwaye emva koko uvelise indawo yamagnetic ukulawula isenzo sevalve yesilayidi, ukuze utshintshe ngokuqhubekayo ubudlelwane bexesha phakathi kwe-crankshaft kunye necamshaft, ukufikelela olona lawulo lwesigaba sevalve.
Ngolu hlengahlengiso, iivalvu zokulawula ioyile zinceda ukwandisa ukusebenza kakuhle kwe-injini, ukuphucula ukuzinza, ukuhambisa i-torque enkulu kunye namandla, ngelixa ziphucula uqoqosho lwamafutha kunye nokunciphisa ukukhutshwa.
Uhlobo kunye nesakhiwo
Iivalve zokulawula ioyile zinokwahlulwa zibe ziindidi ezimbini: iivalve zokulawula ioyile kunye nezivalo zokhuselo. Umsebenzi oyintloko womlawuli woxinzelelo kukulawula uxinzelelo kwinkqubo yokuthintela umonakalo kwinkqubo yokuthambisa ngenxa yoxinzelelo oluphezulu; Ivalve yokukhusela idlala indima ekungaphumelelini komlawuli woxinzelelo ukukhusela i-tubing ekuphukeni ngenxa yoxinzelelo olugqithisileyo.
Ukongeza, kukho i-oyile yokulawula uxinzelelo lwe-oyile ehambelana nesekethe. Xa uxinzelelo lweoyile lungonelanga, umtshintshi uya kuvala kwaye uqalise ukukhanya kwe-alam yoxinzelelo lweoyile kwisixhobo semoto.
Indawo kunye nesicelo
I-valve yokulawula ioli idla ngokufakwa kwi-cylinder inxalenye ye-injini, indawo ethile isemva kwe-camshaft timing pulley kumacala omabini, ngokulandelanayo uxanduva lokuthatha kunye nemisebenzi yokukhupha. Ezi zivalo zinenkangeleko yecylindrical kwaye zineplagi phezulu edibanisa iingcingo ezimbini. Ukongezelela, kukho ezinye iivalve ezibalulekileyo zokulawula ioli kwinkqubo, njenge-valve ekhoyo kumzimba we-cylinder, umsebenzi oyintloko kukulawula ukuhamba kweoli kwi-tile engundoqo kunye ne-vvt; Enye isebenza njengevalve yokubuyisela i-oyile ukuqinisekisa ukuba i-oyile inokubuyiselwa kwi-oyile epanini emva kokuba isithuthi sicinyiwe.
Umsebenzi ophambili wevalvu yokulawula ioyile yemoto kukulawula kunye nokuthintela uxinzelelo lwenkqubo yokuthambisa i-injini ukuba lube phezulu kakhulu. Ngokunciphisa uxinzelelo oluphezulu lwenkqubo, ikhusela uxinzelelo olugqithisileyo ekonakaliseni amacandelo enkqubo yokuthambisa kunye nokuthintela ukuvuza kweoli. Ivalve yokulawula i-oyile iqulunqwe yindibano yomzimba kunye nendibano ye-actuator, yahlulahlulwe yaba luchungechunge lwesihlalo esisodwa, uchungechunge lwezihlalo ezibini, uchungechunge lwemikhono kunye noluhlu oluziqhubelayo lwechungechunge ezine, uluhlu ngalunye lunesicelo salo esikhethekileyo, iingenelo kunye nokungalungi phantsi kweemeko ezahlukeneyo zokusebenza. ...
Indima ethile
Ukunciphisa uxinzelelo oluphezulu lwenkqubo : ivalve yokulawula ioyile ngokulawula unikezelo lweoyile yempompo yeoli, ukuthintela uxinzelelo lweoyile yempompo yeoli iphezulu kakhulu, ngakumbi ngesantya esiphezulu, unikezelo lweoyile yempompo yeoli lukhulu kakhulu, uxinzelelo lweoyile lunyuke kakhulu, ke ivalve yokulawula ioyile ibaluleke kakhulu.
Thintela umonakalo kumacandelo enkqubo yokuthambisa : Uxinzelelo lweoyile olugqithisileyo lunokubangela ukuba ivalve ye-tasht yehydraulic ivale ngokungafanelekanga, uxinzelelo lwesilinda lwehle, kwaye lunokubangela ukugqabhuka kwetyhubhu. I-valve yokulawula ioli ikhusela inkqubo yokuthambisa emonakalweni ngokulawula uxinzelelo.
iqinisekisa ukusebenza kakuhle kunye nokuzinza kwe-injini : kwi-injini ye-valve ye-valve eguquguqukayo, i-valve yokulawula i-oyile iqinisekisa ukulungiswa kwesigaba se-camshaft ngokulawula ngokuchanekileyo utshintsho lwendlela yeoli, ukwenzela ukuba kuqinisekiswe ukuba injini inokufezekisa eyona meko isebenzayo phantsi kweemeko ezahlukeneyo zokusebenza.
Isiphumo sempazamo
Ukuba i-valve yokulawula i-oyile ihluleka, inokubangela ukuba isithuthi simise ngexesha lokuqhuba, kwaye uxinzelelo lwe-oyile luya kunyuka ngokungaqhelekanga, luchaphazela ukusebenza kwesithuthi, njengokuba umxube unzima kakhulu, umsi omnyama ophuma kumbhobho wokukhupha, kwaye amandla ayancipha. Uxinzelelo olugqithisileyo lwe-oyile lunokukhokelela ekwandeni kokusetyenziswa kwepetroli, ukukhutshwa kombhobho ngokugqithisileyo, kunye nesantya esingazinzanga sokungenzi nto, ukonyusa imingcipheko yokhuseleko kunye nomthwalo wezoqoqosho wemoto. Ngoko ke, emva kokuba ivalve yokulawula i-oyile ifunyenwe ingalunganga, kufuneka ilungiswe ngokukhawuleza.
