Liyini ipayipi le-bypass ye-valve ye-waste yemoto
Ipayipi le-bypass ye-automotive valve bypass ibhekisela engxenyeni eseceleni kwesiteshi sikagesi se-turbocharger umsebenzi wayo oyinhloko uwukulawula inani lesisi esikhipha umoya esidlula ku-turbine. I-valve yokudlula igesi ephumayo inezindlela ezimbili: eyodwa ingeyegesi yokukhipha umoya ukuze ishayele i-turbine, kanti enye ingena ngqo epayipini lokukhipha umoya ngevalve yokudlula .
Umsebenzi we-exhaust gas bypass valve
Ukulawula ukugeleza kwegesi ephumayo : I-valve yokukhipha igesi ephumayo ingalungisa inani legesi yokukhipha umoya nge-turbine ngokwesimo sokusebenza senjini, ukuze ilawule isivinini namandla okukhipha enjini, futhi iqinisekise ukuthi injini ingasebenza kahle ngaphansi kwezimo ezihlukene zokusebenza.
vikela injini : Uma injini isebenza ngomthwalo omkhulu noma isivinini esikhulu, ivalvu yokudlula igesi ephumayo inganciphisa inani legesi yokukhipha umoya engena ku-turbine, ivimbele i-turbine ekushiseni ngokweqile, futhi ivikele injini emonakalweni.
Thuthukisa ukonga kukaphethiloli : Ngokulawula kahle ukugeleza kwegesi ephumayo, ivalvu yokudlula igesi ephumayo ingasiza injini ukuba ifinyelele ekusebenziseni uphethiloli ngokuphumelelayo ngaphansi kwezimo ezihlukene zokusebenza, ngaleyo ndlela yehlise ukusetshenziswa kukaphethiloli.
Umgomo wokusebenza we-valve yokukhipha igesi ephumayo
Ama-valve e-exhaust gas bypass ngokuvamile akhiwa ama-valve, iziphethu namapiston. Lapho injini ingaphansi komthwalo omkhulu, i-valve iyavulwa, futhi ingxenye yegesi yokukhipha igesi ikhishwa ngokuqondile epayipini lokukhipha umoya nge-valve ye-bypass ukunciphisa inani legesi yokukhipha engena ku-turbine; Uma umthwalo wenjini uphansi, i-valve ivaliwe futhi yonke igesi yokukhipha ingena ku-turbine, ikhulisa isivinini namandla okukhipha e-turbine.
Ukugcinwa nokuxilongwa kwamaphutha
ukuhlola okuvamile : hlola njalo isimo sokusebenza kwevalvu yegesi ephumayo ukuze uqinisekise ukuvuleka nokuvalwa kwayo okuvamile.
Ukuhlanza nokunakekela : Gcina ivalvu yegesi ephumayo ephumayo kanye nezingxenye zayo ezihambisanayo zihlanzekile ukuze uvimbele ukunqwabelana kwekhabhoni nokungcola ukuthi kuphazamise ukusebenza kwayo okuvamile.
ukuhlonzwa kwephutha : Uma ukusebenza kwenjini kutholakala ukuthi kwehlile noma ukusetshenziswa kukaphethiloli kunyuswa, ivalvu yokudlula igesi ephumayo kufanele ihlolwe ukuze kubonakale umonakalo noma ukwehluleka, futhi ilungiswe noma ishintshwe ngesikhathi.
Iqhaza eliyinhloko lepayipi le-exhaust bypass yezimoto ukulawula inani legesi ephumayo edlula ku-turbine ukuvikela injini nokwenza ngcono ukusebenza. .
I-valve yokudlula igesi ephumayo itholakala ohlangothini lwesiteshi segesi ephumayo se-turbocharger futhi indima yayo ukulawula umfutho okhulayo ngokulawula inani legesi ephumayo edlula ku-turbine. Uma ijubane lenjini likhuphuka, umthamo wegesi yokukhipha umoya uyakhuphuka, nesivinini se-supercharger nomfutho we-boost nawo uyakhuphuka. Ukuze kuvinjwe umfutho we-boost ukuthi ungadluli umthamo omkhulu wenjini, i-valve yokukhipha igesi ephumayo izovulwa lapho umfutho we-boost ufinyelela phezulu, okuvumela ingxenye yegesi yokukhipha igesi ingene ngqo epayipini lokukhipha umoya, ngaleyo ndlela kwehlise umfutho we-boost nokuvikela injini. Ngaphezu kwalokho, i-valve ye-bypass ye-exhaust gas nayo ingavulwa lapho singekho isidingo samandla amakhulu, ukuze injini isebenze esimweni esifisa ngokwemvelo, inciphise umthwalo wemishini kanye nokusetshenziswa kukaphethiloli.
Kwezinye izimo, i-valve ye-bypass yegesi ephumayo nayo izovuleka ngokuzenzakalelayo. Isibonelo, lapho injini isanda kuqalisa futhi ingafudunyeziwe, ukuze kwandiswe izinga lokushisa lenjini futhi kuncishiswe isikhathi sokushisa ngaphambili kwesiguquli se-catalytic yezindlela ezintathu, i-exhaust gas bypass valve izokwandisa ukugeleza kwegesi ephumayo. Ngaphezu kwalokho, ngemva kokuba injini icishiwe, i-valve yokukhipha igesi ephumayo nayo izovulwa ukuze kuthuthukiswe ukukhishwa okushelelayo kwegesi ephumayo yangaphakathi.
