Ithangi lokubamba kawoyela noma ukubamba uwoyela kungaba yithuluzi elifakwe ohlelweni lwendawo yokuphefumula ye-cam / cranksecange emotweni. Ukufaka i-Oil Catch Tank (Can) ihlose ukunciphisa inani lama-vapors kawoyela asakazeke ngokudla kwenjini.
Umoya omncane we-cranksecange
Ngesikhathi sokusebenza okujwayelekile kwenjini yemoto, amanye amahepole avela kusilinda adlula amasongo e-piston awela phansi. Ngaphandle komoya omncane lokhu kungacindezela i-crankcase futhi kubangele izingqinamba ezinjengokuntuleka kokubekwa uphawu kwendandatho ye-piston kanye nokulimala kwamafutha kawoyela.
Ukuze ugweme lokhu, abakhiqizi bakha uhlelo lokungena komoya omncane. Ekuqaleni lokhu bekuvame ukusetha okuyisisekelo lapho isihlungi sibekwe ngaphezulu kwecala le-CAM kanye nengcindezi kanye nama-vapors kwathathwa emkhathini. Lokhu kuthathwa njengokungamukeleki njengoba kuvunyelwe ukuthungwa kanye no-oyili ukuba kungasuselwa emkhathini okwabangela ukungcoliswa. Kungadala futhi nezinkinga zabahlali bemoto njengoba kungadonswa ngaphakathi kwemoto, eyayivame ukungathandeki.
Cishe ngo-1961 kwadalwa umklamo omusha. Lo mklamo uhole umoya wokushaywa kwe-crank. Lokhu bekusho ukuthi ama-vapors kanye ne-oyili inkungu angashiswa futhi axoshwe emotweni ngokuqothuka. Akukhona kuphela ukuthi lokhu kube mnandi kakhulu ekwenzeni imoto abahlala kuyo futhi kusho ukuthi inkunzi yamafutha ayikhishwa emoyeni noma emgwaqweni endabeni yezinhlelo zomoya osalungiswa.
Izinkinga ezibangelwa ukuphefumula kwe-crank crank
Kunezinkinga ezimbili ezingabangelwa ukuhambisa umjikelezo ovuthayo ohlelweni lokudla kwenjini.
Udaba oluphambili lunokwakhiwa kwamafutha ngaphakathi kwamapayipi okudla kanye ne-manifold. Ngesikhathi sokusebenza okujwayelekile kwenjini ukugcwala ngokweqile kanye namafutha avela ecaleni lama-crank kuvunyelwe ukungena ohlelweni lokudla. I-oyili inkungu ipholile futhi izingqimba ngaphakathi kwepayipi yokudla kanye ne-manifold. Ngokuhamba kwesikhathi lolu handla lungakha futhi i-sludge obukhulu inganqwabelana.
Lokhu kwenziwe kubi kakhulu ngokwethulwa kohlelo lokuphinda luphelelwe yigesi (EGR) ezimotweni zanamuhla. Ama-Vapors kawoyela angaxubana nama-gasse aqedwe kabusha aqedwe kanye ne-soot okwakheka lapho ungena khona maphakathi nama-valve njll. Lesi singqimba esidlulayo ngokuhamba kwesikhathi siyaqina. Kuzobe sekuqala ukuhlanganisa umzimba we-throttle, ama-swirl flaps, noma ngisho nama-valves wokudla kwizinjini ezichazwe ngqo.
Ukuba nokwakhiwa kwe-sludge kungadala ukusebenza okuphansi ngenxa yomphumela wokukhawulelwa okunakho ekuhambeni komoya enjini. Uma ukwakhiwa kuba ngokweqile emzimbeni we-throttle kungadala i-idling empofu njengoba kungavimba ukugeleza komoya ngenkathi ipuleti le-throttle livaliwe.
Ukufanekisa ithangi lokubamba (ukukala) kuzonciphisa inani le-vapor kawoyela elifinyelela ephethini lokudla kanye negumbi lokuhlanza. Ngaphandle komphunga kawoyela i-soot kusuka ku-egr valve ngeke ihlanganise kakhulu ekungeneni okuzogcina ukuthambekela ekubeni ngibe khona
