Iyini i-valve yokungenisa imoto kanye ne-exhaust valve
I-valve yokukhipha izimoto kanye ne-exhaust iyingxenye ebalulekile yenjini, enesibopho sokulawula inqubo yokukhipha kanye nokukhipha umoya wenjini.
Izincazelo kanye nemisebenzi yama-valve okungenisa nawokukhipha
(I-Valve Edonsayo) : Umsebenzi oyinhloko wevalvu edonsayo ukudonsa umoya enjinini, uwuxube nophethiloli bese uwushisa ukuze unikeze amandla enjini. Ukuvulwa nokuvalwa kwe-valve yokungena kulawulwa yi-camshaft ukuze kuqinisekiswe ukungena komoya okubushelelezi kusilinda .
I-Exhaust Valve : umsebenzi we-valve yokukhipha umoya ukukhipha igesi ephumayo ngemva kokusha enjinini, kuyilapho usiza ukukhipha ukushisa nokugcina ukusebenza okuvamile kwenjini. Ukuvulwa nokuvalwa kwe-valve yokukhipha umoya nakho kulawulwa yi-camshaft.
Umehluko phakathi kwama-valve okungenisa nawokukhipha
Umehluko wokusebenza : I-valve yokudonsa inesibopho sokungena komoya, kuyilapho i-valve yokukhipha umoya inesibopho segesi yokukhipha umoya. Ivalvu yokudonsa ivamise ukuba nkulu kune-exhaust valve ngoba kudingeka kubanjwe umoya omningi.
Izici zomzimba : I-valve yokudonsa imvamisa itholakala ohlangothini lwenjini eduze nesistimu edonsayo, futhi i-valve yokukhipha umoya itholakala ekugcineni eduze kwesistimu yokukhipha umoya. Ngaphezu kwalokho, ivolumu ye-valve yokudonsa ngokuvamile iba nkulu kunaleyo ye-valve yokukhipha umoya.
Umgomo wokusebenza wama-valve wokungenisa kanye nokukhipha
inqubo yokuthatha : lapho kuvulwa ivalvu yokudonsa, umoya ungena kusilinda ngesihlungi somoya bese uxutshwa nophethiloli okhishwa umbhobho womjovo kaphethiloli ukuze ushiswe.
inqubo yokukhipha umoya : igesi ephumayo ngemva kokusha ikhishwa ngevalvu yokukhipha umoya, futhi ikhiphe ingxenye yokushisa ukuze isize injini ishise.
Ukuthuthukiswa kobuchwepheshe kwama-valve okungenisa nawokukhipha
Ngokuthuthuka kobuchwepheshe, ubuchwepheshe obunama-valve amaningi busetshenziswa kabanzi. Izinjini zesimanje zivame ukufaka ama-valve amaningi isilinda, njengama-valve amane noma ngaphezulu, ukuthuthukisa ukusebenza kahle kokuthatha kanye nekhwalithi yokuvutha. Lo mklamo uvumela uwoyela negesi ukuthi kuxubane ngokulinganayo futhi kushise ngokugcwele, ngaleyo ndlela kuthuthukiswe ukusebenza kwenjini nokonga kukaphethiloli.
Imisebenzi esemqoka ye-exhaust valve kanye ne-exhaust valve ihlanganisa ukulawula ukungena komoya nophethiloli, ukukhipha igesi ephumayo kanye nokukhipha ukushisa. I-valve yokudonsa inesibopho sokudonsa umoya enjinini, iwuxube nophethiloli futhi uyishise ukuze inikeze amandla enjini; I-valve yokukhipha umoya inesibopho sokukhipha igesi yokukhipha umoya ngemva kokuvutha, futhi isiza injini ukuba ikhiphe ukushisa, igcine izinga lokushisa langaphakathi lifanelekile.
Isenzo se-valve yokungena
Umsebenzi oyinhloko we-valve yokudonsa ukudonsa umoya enjinini bese uwuxuba nophethiloli ukuze ivuthe. Ukuvulwa nokuvalwa kwe-valve yokudonsa kulawulwa yi-camshaft yenjini ukuze kuqinisekiswe ukuthi umoya owanele udonswa ngesikhathi esifanele ukuze kuqinisekiswe ukusebenza okuvamile kwenjini namandla okukhipha amandla.
Ivalvu yokudonsa imvamisa yakhelwe ukuba ibe nkulu ukuze idonse umoya owengeziwe njengoba ipiston yehla.
Indima ye-valve yokukhipha umoya
Umsebenzi oyinhloko we-valve yokukhipha umoya ukukhipha igesi ephumayo enjinini ngemva kokusha nokusiza injini ukuba ikhiphe ukushisa. Ukuvuleka nokuvalwa kwe-valve exhaust nakho kulawulwa yi-camshaft, ukuqinisekisa ukuthi i-exhaust gas ikhishwa ngesikhathi esifanele ukuvimbela injini ekushiseni ngokweqile. Idizayini ye-exhaust valve incane uma kuqhathaniswa futhi igxile kugesi ephumayo esebenza kahle.
Umgomo wokusebenza kanye nezici zesakhiwo samavalvu okungenisa kanye nokukhipha umoya
Ama-valve okungenisa nawokuqeda avulwa futhi avalwe ngokulawulwa kwe-camshaft. I-camshaft ishayela ukunyakaza kwe-valve ngokunyakaza kwemishini ukuze ibone ukushintshwa kwe-valve yokukhipha kanye ne-exhaust valve. I-valve yokudonsa ivuleka lapho ipiston ihambela phansi ukuze ihogele umoya; Ivalvu yokukhipha umoya iyavuleka lapho ipiston ihambela phezulu ukuze ikhiphe igesi yokukhipha umoya.
Ngaphezu kwalokho, ubuchwepheshe obunama-valve amaningi bubuye busetshenziswe ezinjinini zezimoto zesimanje, ezinama-valve amaningi ngesilinda ukuze kuthuthukiswe ukudonsa nokukhipha amandla.
