Umsebenzi wevalvu yokulawula ukuhamba kweoyile yenjini yemoto
Ivalvu yokulawula ukuhamba kwepompo yeoyile yemoto, edla ngokubizwa ngokuba yivalvu yokunciphisa uxinzelelo lwepompo yeoyile, isebenza ngokuyintloko ukulawula nokulawula uxinzelelo lweoyile oluphezulu kwinkqubo yokuthambisa injini, ukuthintela umonakalo kwizinto ezifana nepompo yeoyile, iindlela zeoyile, kunye nezitywini ngenxa yoxinzelelo olugqithisileyo.
Umgaqo othile wokusebenza kunye nomsebenzi ngolu hlobo lulandelayo:
Ulawulo loxinzelelo: Xa isantya senjini sisanda okanye i-oyile isanda, ukuhanjiswa kweoyile yipompo yeoyile kuya kwanda, nto leyo ebangela ukuba uxinzelelo lweoyile kwindawo ephambili yeoyile lunyuke. Ulwakhiwo lwangaphakathi lwevalvu ethintelayo luqulathe intwasahlobo kunye nesiseko sevalvu. Xa uxinzelelo lweoyile ludlula umda wokhuseleko omiselweyo, uxinzelelo lweoyile luya koyisa amandla entwasahlobo, lutyhale isiseko sevalvu, kwaye luvumele enye yeoyile ukuba idlule kwivalvu ethintelayo ibuyele ngqo kwizibuko lokungenisa ipompo yeoyile (oko kukuthi, "ukukhululeka koxinzelelo"), ngaloo ndlela kuzinzisa uxinzelelo lweoyile kwindawo ephambili yeoyile ngaphakathi koluhlu olufanelekileyo.
Ukukhusela ukhuseleko lwenkqubo: Uxinzelelo olugqithisileyo lweoyile lunokubangela ukuba isihluzi seoyile siqhekeke, amalungu ombhobho yeoyile avuza, iigaskets zevalvu ezikwigumbi levalvu, okanye izitywini zeoyile ngaphambili nangasemva kwe-crankshaft, njl.njl. ukuba zonakale. Ivalvu ethintelayo, njengesixhobo sokhuseleko, inokuthintela ngempumelelo ezo mpazamo kwaye iqinisekise ukusebenza okuthembekileyo kwexesha elide kwenkqubo yokuthambisa.
Akukho lawulo lwangaphandle olufunekayo: Le valve sisakhiwo esenziwe ngoomatshini esifezekisa ulawulo oluzenzekelayo oluxhomekeke kuxinzelelo lweoyile ngokwalo. Ayifuni nxaxheba yeyunithi yolawulo lwe-elektroniki (ECU). Isakhiwo silula kwaye impendulo ikhawuleza.
Kufuneka kuqatshelwe ukuba kwezinye izinto, "ivalvu yokulawula ukuhamba" idla ngokubhekisa kwizinto ezifanayo kwinkqubo yokuqhuba okanye kwinkqubo yepetroli, ngelixa kwinkqubo yepompo yeoyile, igama elichanekileyo ngakumbi lithi "ivalvu yokukhawulela" okanye "ivalvu yokhuseleko", enomsebenzi ophambili kukukhawulela uxinzelelo endaweni yokulawula ukuhamba nje.
Umonakalo kwivalvu ye-electromagnetic control flow pump ye-oyile (edla ngokubhekisa kwivalvu ye-electromagnetic control pressure ye-oyile okanye izinto ezifanayo) uya kuchaphazela kakhulu ukusebenza kwesiqhelo kwesithuthi. Akukhuthazwa ukuba uqhubeke nokuqhuba.
Le valve ye-electromagnetic yinxalenye ebalulekileyo yokulawula inkqubo yokuthambisa injini, enoxanduva lokulawula uxinzelelo lweoyile kunye nokuhamba kwayo ukuqinisekisa ukuba inxalenye nganye yenjini ifumana ukuthambisa okwaneleyo. Nje ukuba yonakele, iya kubangela uxinzelelo lweoyile olungaqhelekanga, ngaloo ndlela ibangele uthotho lweengxaki zetsheyini.
Iimpembelelo eziphambili ziquka:
Ukuthambisa injini okunganelanga: Uxinzelelo lweoyile oluphantsi okanye olungazinzanga lubangela ukuba iindawo zangaphakathi zenjini (ezifana nee-camshafts, iindlela zevalvu, iibheringi, njl.njl.) zingafumani ukuthambisa okwaneleyo, nto leyo ekhawulezisa ukuguguleka.
Ingxolo engaqhelekanga yenjini kunye nokungcangcazela: Ukuthambisa okungekho semgangathweni kuya kubangela ingxolo ebonakalayo yenjini (efana "nokungqubana") kwaye kuhamba nokungazinzi okanye ukungcangcazela ngexesha lokuqhuba.
Ukulahleka kwamandla kunye nobuthathaka bokukhawulezisa: Kwezinye iimodeli, ivalvu ye-electromagnetic yokulawula uxinzelelo lweoyile inxulunyaniswa nenkqubo ye-variable valve timing (VVT). Nje ukuba yonakele, iya kubangela ixesha elingaqhelekanga levalvu, okubangela ukuphazamiseka kwamandla kunye nokukhawulezisa okucothayo.
Umngcipheko wokutshisa kakhulu injini: Ioyile ayigcini nje ngokuthambisa kodwa ikwathatha inxaxheba ekuchithekeni kobushushu. Ukuhamba okungaqhelekanga kunokuchaphazela ukusebenza kakuhle kokutshisa ubushushu kwenjini, okwandisa umngcipheko wokutshisa kakhulu.
Umda wokukhusela injini ngokuzenzekelayo: I-ECU (iyunithi yokulawula injini) yezithuthi zanamhlanje iya kuqalisa indlela yokukhusela xa ibona uxinzelelo lweoyile olungaqhelekanga, inciphise isantya senjini kunye nombane ophumayo ukuthintela umonakalo omkhulu. Ngeli xesha, imoto inokuthi "ibuyele ekhaya" ize ingasebenzi kakuhle.
Umonakalo omkhulu onokubakho kwinjini: Ukuqhuba ixesha elide ivalvu ye-electromagnetic yonakele kunokubangela ukuba injini ifumane amanqaku esilinda, ukuxhuzula, kunye neminye imonakalo engenakulungiseka. Ixabiso lokulungisa liphezulu kakhulu. Ingcebiso:
Yima ngoko nangoko ukuze ujonge: Ukuba ideshibhodi ibonisa isibane sokulumkisa uxinzelelo lweoyile, isibane sempazamo yenjini siyakhanya, okanye ukuba uziva ulahlekelwe ngamandla okanye iingxolo ezingaqhelekanga, kufuneka umise imoto ngokukhuselekileyo.
Nxibelelana nolungiso lweengcali: Musa ukuzama ukuqhuba ngamandla. Endaweni yoko, nxibelelana nesikhungo sokulungisa sengcali ukuze ufumanise ukuba ngaba kukusilela kwevalvu ye-electromagnetic kwaye uyitshintshe ngokukhawuleza.
Ukugcinwa rhoqo: Kucetyiswa ukuba kuhlolwe inkqubo yesekethe yeoyile rhoqo kwiikhilomitha ezingama-20,000 okanye ngaphezulu kwaye kusetyenziswe ioyile yenjini esemgangathweni ophezulu ukunciphisa umngcipheko wokwakheka kwekhabhoni kunye nokuvaleka kwayo, ngaloo ndlela kwandise ubomi bevalvu ye-electromagnetic.
Ukuqukumbela, emva kokuba ivalvu ye-electromagnetic control flow pump yeoyile yonakele, ayizukuphela nje kokuba ukusebenza kwesithuthi kuya kwehla kakhulu, kodwa kukwakho nengozi enkulu yokhuseleko. Kufuneka uyeke ngoko nangoko ukuqhuba kwaye wenze ulondolozo.
