Iyini ipayipi le-bypass valve yemoto
Ipayipi lokudlula imfucuza yemoto libhekisela engxenyeni etholakala ohlangothini lwesiteshi sokukhipha umoya se-turbocharger umsebenzi wayo oyinhloko ukulawula inani legesi yokukhipha umoya edlula ku-turbine. I-valve yokudlula igesi yokukhipha umoya inezindlela ezimbili: enye ingeyegesi yokukhipha umoya ukushayela i-turbine, kanti enye ingena ngqo epayipini lokukhipha umoya nge-valve yokudlula umoya .
Umsebenzi we-valve ye-exposure gas bypass
Ukulawula ukugeleza kwegesi yokukhipha umoya: I-valve ye-extraction gas bypass ingakwazi ukulungisa inani legesi yokukhipha umoya nge-turbine ngokwesimo sokusebenza senjini, ukuze ilawule isivinini namandla okukhipha e-turbine, futhi iqinisekise ukuthi injini ingasebenza kahle ngaphansi kwezimo zokusebenza ezahlukene.
vikela injini: Uma injini isebenza ngomthwalo omkhulu noma ngesivinini esikhulu, i-valve ye-exhaust gas bypass inganciphisa inani legesi yokukhipha engena ku-turbine, ivimbele i-turbine ekushiseni ngokweqile, futhi ivikele injini ekulimaleni.
Thuthukisa ukonga uphethiloli: Ngokulawula ngokunembile ukugeleza kwegesi ephumayo, ivalvu yokudlula igesi ephumayo ingasiza injini ukuthi ifinyelele ukusetshenziswa kukaphethiloli okuphumelelayo ngaphansi kwezimo zokusebenza ezahlukene, ngaleyo ndlela inciphise ukusetshenziswa kukaphethiloli.
Umgomo wokusebenza we-valve ye-extra gas bypass valve
Amavalvu egesi yokukhipha umoya avame ukwakhiwa ngamavalvu, iziphethu nama-piston. Uma injini ingaphansi komthwalo omkhulu, ivalvu iyavulwa, bese ingxenye yegesi yokukhipha umoya ikhishwa ngqo epayipini lokukhipha umoya ngevalvu ye-bypass ukuze kuncishiswe inani legesi yokukhipha umoya engena kwi-turbine; Uma umthwalo wenjini uphansi, ivalvu iyavalwa bese yonke igesi yokukhipha umoya ingena kwi-turbine, okwandisa isivinini namandla okukhipha i-turbine.
Ukunakekelwa kanye nokuxilongwa kwamaphutha
ukuhlolwa okuvamile: hlola njalo isimo sokusebenza kwevalvu yokudlula igesi ephumayo ukuqinisekisa ukuvulwa nokuvalwa kwayo okuvamile.
Ukuhlanza nokulungisa: Gcina ivalvu yokudlula igesi ephumayo kanye nezingxenye zayo zihlanzekile ukuvimbela ukuqongelela kwekhabhoni kanye nokungcola kungathinti ukusebenza kwayo okuvamile.
Ukuxilongwa kwephutha: Uma ukusebenza kwenjini kutholakala ukuthi kwehlisiwe noma ukusetshenziswa kukaphethiloli kukhuphukile, ivalvu yokudlula igesi yokukhipha umoya kufanele ihlolwe ukuthi ayinawo yini umonakalo noma ukwehluleka, bese ilungiswa noma ishintshwa ngesikhathi.
Indima eyinhloko yepayipi lokukhipha umoya wezimoto ukulawula inani legesi yokukhipha umoya edlula ku-turbine ukuvikela injini nokuthuthukisa ukusebenza kwayo.
I-valve ye-exhaust gas bypass itholakala ohlangothini lwesiteshi se-exhaust gas se-turbocharger futhi indima yayo ukulawula ingcindezi yokukhulisa ngokulawula inani legesi yokukhipha edlula ku-turbine. Lapho ijubane lenjini landa, ivolumu yegesi yokukhipha nayo iyanda, futhi ijubane le-supercharger kanye nengcindezi yokukhulisa nakho kuyakhula. Ukuze kuvinjelwe ingcindezi yokukhulisa ukuthi ingadluli umthamo omkhulu wokuthwala wenjini, i-valve ye-exhaust gas bypass izovulwa lapho ingcindezi yokukhulisa ifinyelela phezulu, okuvumela ingxenye yegesi yokukhipha ngqo epayipini lokukhipha, ngaleyo ndlela kuncishiswe ingcindezi yokukhulisa futhi kuvikelwe injini . Ngaphezu kwalokho, i-valve ye-exhaust gas bypass nayo ingavulwa lapho kungekho sidingo samandla amakhulu, ukuze injini isebenze esimweni sokufuthwa ngokwemvelo, kuncishiswe umthwalo womshini kanye nokusetshenziswa kukaphethiloli .
Kwezinye izimo, ivalvu yokudlula igesi yokukhipha nayo izovuleka ngokuzenzakalelayo. Isibonelo, uma injini isanda kuqala futhi ingafudunyezwanga, ukuze kwandiswe izinga lokushisa lenjini futhi kuncishiswe isikhathi sokushisa kwangaphambili se-catalytic converter enezindlela ezintathu, ivalvu yokudlula igesi yokukhipha izokwandisa ukugeleza kwegesi yokukhipha . Ngaphezu kwalokho, ngemva kokuba injini icishiwe, ivalvu yokudlula igesi yokukhipha nayo izovulwa ukuze kukhuthazwe ukukhishwa okubushelelezi kwegesi yokukhipha yangaphakathi .
