Yintoni umbhobho wenkunkuma yevalve yemoto
Umbhobho we-valve yenkunkuma yeenqwelo-mafutha ubhekiselele kwicandelo elibekwe kwicala lomjelo wokuphuma we-turbotshaja umsebenzi walo ophambili ikukulawula ubungakanani begesi yokuphuma edlula kwi-iturbine. Ivalve yegesi yokuphuma ineendlela ezimbini: enye yeyokukhupha irhasi ukuqhuba i-iturbine, kwaye enye ingena ngqo kumbhobho wokuphuma ngevalve yokudlula.
Umsebenzi wevalve yegesi yokuphuma
Ukulawula ukuhamba kwegesi ephumayo : Ivalve yegesi ephumayo inokulungelelanisa ubungakanani begesi yokukhupha nge turbine ngokwemeko yokusebenza yeinjini, ukuze kulawulwe isantya kunye namandla aphumayo einjini yomoya, kunye nokuqinisekisa ukuba injini inokuqhuba ngokufanelekileyo phantsi kweemeko ezahlukeneyo zokusebenza.
khusela i-injini : Xa i-injini isebenza kumthwalo ophezulu okanye isantya esiphezulu, ivalve yokuphuma kwegesi ephumayo inokunciphisa ubungakanani begesi yokuphuma engena kwi-injini yomoya, ithintele i-injini ekutshiseni ngokugqithisileyo, kwaye ikhusele i-injini emonakalweni.
Ukuphucula uqoqosho lwamafutha : Ngokulawula ngokuchanekileyo ukuhamba kwerhasi yokukhupha, ivalve yegesi yokuphuma inokunceda i-injini ifezekise ukusetyenziswa kwamafutha ngokufanelekileyo phantsi kweemeko ezahlukeneyo zokusebenza, ngaloo ndlela inciphisa ukusetyenziswa kwamafutha.
Umgaqo osebenzayo wokukhupha i-valve ye-bypass yegesi
Iivalvu zegesi eziphumayo zidla ngokuqulunqwa ngeevalvu, imithombo kunye neepiston. Xa injini iphantsi komthwalo ophezulu, i-valve ivuliwe, kwaye inxalenye yegesi yokukhupha ikhutshwe ngokuthe ngqo kumbhobho wokukhupha ngokusebenzisa i-valve ye-bypass ukunciphisa ubungakanani begesi yokuphuma engena kwi-turbine; Xa umthwalo we-injini uphantsi, ivalve ivaliwe kwaye yonke igesi yokukhupha ingena kwi-injini yomoya, inyusa isantya kunye namandla aphumayo e-injini yomoya.
Ukugcinwa kunye nokuxilongwa kweempazamo
ukujonga rhoqo : jonga rhoqo imeko yokusebenza kwevalve yegesi yokuphuma ukuze uqinisekise ukuvulwa nokuvalwa kwayo ngokuqhelekileyo.
Ukucoca kunye nokugcinwa : Gcina ivalve yegesi ephumayo kunye neendawo zayo ezihambelanayo zicocekile ukuthintela ukuqokelelwa kwekhabhoni kunye nokungcola kuchaphazele ukusebenza kwayo okuqhelekileyo.
ukuxilongwa kwempazamo : Ukuba ukusebenza kwe-injini kufunyaniswa kuncitshisiwe okanye ukusetyenziswa kwepetroli kwandisiwe, ivalve yokuphuma kwegesi yokuphuma kufuneka ijongwe ukonakala okanye ukusilela, kwaye ilungiswe okanye itshintshwe ngexesha.
Indima ephambili ye-automotive exhaust bypass pipe kukulawula ubungakanani begesi yokukhupha edlula kwi-injini yokukhusela i-injini kunye nokwandisa ukusebenza. ...
Ivalve yegesi ephumayo ibekwe kwicala lomjelo werhasi ye-turbocharger kwaye indima yayo kukulawula uxinzelelo lonyuso ngokulawula ubungakanani begesi ephumayo edlula kwi-injini yomoya. Xa isantya se-injini sinyuka, umthamo wegesi wokukhupha nawo uyanda, kwaye isantya se-supercharger kunye noxinzelelo lokunyusa nalo luyanda. Ukuze kuthintelwe uxinzelelo lokunyusa ukuba lugqithise ubungakanani bomthamo we-injini, ivalve yegesi yokukhupha igesi iya kuvulwa xa uxinzelelo lonyuso lufikelela kwinqanaba eliphezulu, livumela inxalenye yegesi yokukhupha ngokuthe ngqo kumbhobho wokukhupha, ngaloo ndlela kunciphisa uxinzelelo kunye nokukhusela injini. Ukongeza, i-valve yokuphuma kwegesi ephumayo inokuvulwa kwakhona xa kungekho mfuneko yamandla amakhulu, ukwenzela ukuba injini ikwazi ukusebenza kwimeko enqwenelekayo ngokwendalo, ukunciphisa umthwalo womatshini kunye nokusetyenziswa kwepetroli.
Kwezinye iimeko, i-valve yokuphuma kwegesi ephumayo iya kuvula ngokuzenzekelayo. Umzekelo, xa i-injini isandula ukuqalisa kwaye ingafudumezi, ukwenzela ukwandisa ubushushu be-injini kunye nokunciphisa ixesha lokufudumeza kwe-converter ye-catalytic yeendlela ezintathu, i-valve yokukhupha i-gas bypass valve iya kwandisa ukuhamba kwegesi ephumayo. Ukongeza, emva kokuba i-injini icinyiwe, i-valve ye-exhaust ye-gas bypass iya kuvulwa ukukhuthaza ukukhutshwa kakuhle kwegesi yangaphakathi yokukhupha.
