Yintoni ivalvu yokungenisa kunye neyokukhupha imoto
Ivalvu yokungenisa kunye neyokukhupha iimoto yinxalenye ebalulekileyo yenjini, enoxanduva lokulawula inkqubo yokungenisa kunye nokukhupha iimoto kwinjini.
Iinkcazo kunye nemisebenzi yeevalvu zokungenisa nezokukhupha umoya
(Ivalvu yokungenisa): Umsebenzi ophambili wevalvu yokungenisa kukutsala umoya ungene enjinini, uwuxube nepetroli uze uwutshise ukuze injini ikwazi ukukhupha amandla. Ukuvulwa nokuvalwa kwevalvu yokungenisa kulawulwa yi-camshaft ukuqinisekisa ukufikelela komoya otyibilikayo kwisilinda.
Ivalvu yokukhupha umoya: umsebenzi wevalvu yokukhupha umoya kukukhupha igesi yokukhupha umoya emva kokutsha ukuya kwinjini, ngelixa inceda ekukhupheni ubushushu kwaye igcine ukusebenza okuqhelekileyo kwenjini. Ukuvulwa nokuvalwa kwevalvu yokukhupha umoya kulawulwa yi-camshaft.
Umahluko phakathi kweevalvu zokungenisa kunye nezokukhupha umoya
Umahluko osebenzayo: Ivalvu yokungenisa umoya inoxanduva lokungenisa umoya, ngelixa ivalvu yokukhupha umoya inoxanduva lwegesi yokukhupha umoya. Ivalvu yokungenisa umoya idla ngokuba nkulu kunevalvu yokukhupha umoya kuba kufuneka kubanjwe umoya omninzi.
Iimpawu zomzimba: Ivalvu yokungenisa umoya idla ngokuba kwicala lenjini kufutshane nenkqubo yokungenisa umoya, kwaye ivalvu yokukhupha umoya ikwisiphelo kufutshane nenkqubo yokukhupha umoya. Ukongeza, umthamo wevalvu yokungenisa umoya udla ngokuba mkhulu kunowevalvu yokukhupha umoya.
Umgaqo wokusebenza kweevalvu zokungenisa kunye nezokukhupha
Inkqubo yokungenisa: xa ivalvu yokungenisa ivuliwe, umoya ungena kwisilinda ngesihluzo somoya uze uxutywe namafutha akhutshwa yi-nozzle ye-fuel injection yokutshisa.
Inkqubo yokukhupha umoya: igesi yokukhupha umoya emva kokutsha ikhutshwa ngevalvu yokukhupha umoya, kwaye isusa inxalenye yobushushu ukunceda injini ifudumale.
Uphuhliso lobuchwephesha lweevalvu zokungenisa kunye nezokukhupha umoya
Ngophuhliso lwetekhnoloji, iteknoloji yeevalvu ezininzi isetyenziswa kakhulu. Iinjini zanamhlanje zihlala zinevalvu ezininzi kwisilinda nganye, njengevalvu ezine nangaphezulu, ukuphucula ukusebenza kakuhle kokungenisa kunye nomgangatho wokutsha. Olu yilo luvumela ioyile negesi ukuba zixubane ngokulinganayo kwaye zitshise ngokupheleleyo, ngaloo ndlela ziphucula ukusebenza kwenjini kunye nokonga amafutha.
Imisebenzi ephambili yevalvu yokungena kwemoto kunye nevalvu yokukhupha umoya ibandakanya ulawulo lokungena komoya kunye nepetroli, ukukhupha igesi yokukhupha umoya kunye nokusasazwa kobushushu. Ivalvu yokungenisa umoya inoxanduva lokutsala umoya ungene enjinini, ukuwuxuba nepetroli kwaye uyitshise ukuze inike amandla enjini; Ivalvu yokukhupha umoya inoxanduva lokukhupha igesi yokukhupha umoya emva kokutsha, kwaye inceda injini ukuba isasaze ubushushu, igcine ubushushu bangaphakathi bufanelekile.
Isenzo sevalvu yokungenisa
Umsebenzi ophambili wevalvu yokungenisa umoya kukutsala umoya ungene enjinini uze uwuxube nepetroli ukuze kutshiswe. Ukuvulwa nokuvalwa kwevalvu yokungenisa umoya kulawulwa yi-camshaft yenjini ukuqinisekisa ukuba kutsalwa umoya owaneleyo ngexesha elifanelekileyo ukuqinisekisa ukusebenza okuqhelekileyo kwenjini kunye nokukhupha amandla.
Ivalvu yokungenisa umoya idla ngokuba nkulu ukuze ikwazi ukutsala umoya omninzi njengoko i-piston isihla.
Indima yevalvu yokukhupha umoya
Umsebenzi ophambili wevalvu yokukhupha umoya kukukhupha igesi ephuma kwinjini emva kokutsha kunye nokunceda injini ukuba ikhuphe ubushushu. Ukuvulwa nokuvalwa kwevalvu yokukhupha umoya kulawulwa yi-camshaft, ukuqinisekisa ukuba igesi ephumayo ikhutshwa ngexesha elifanelekileyo ukuthintela injini ukuba ingatshisi kakhulu. Uyilo lwevalvu yokukhupha umoya luncinci kwaye lugxile kwigesi ephumayo esebenzayo.
Umgaqo wokusebenza kunye neempawu zesakhiwo seevalvu zokungena kunye nezokukhupha umoya
Iivalvu zokungenisa kunye nezokukhupha umoya zivulwa kwaye zivalwe ngolawulo lwe-camshaft. I-camshaft iqhuba intshukumo yevalvu ngokuhamba koomatshini ukuze kuphume utshintsho lwevalvu yokungenisa kunye nevalvu yokukhupha umoya. Ivalvu yokungenisa umoya ivulwa xa i-piston isiya ezantsi ukuze iphefumle umoya; Ivalvu yokukhupha umoya ivulwa xa i-piston isiya phezulu ukuze ikhuphe igesi yokukhupha umoya.
Ukongeza, itekhnoloji yeevalvu ezininzi ikwasetyenziswa kwiinjini zeemoto zanamhlanje, kunye neevalvu ezininzi ngesilinda nganye ukuphucula ukusebenza kakuhle kokungenisa kunye nokuphuma komoya.
