I-oil tank tank noma i-oil catch can iyisisetshenziswa esifakwe ku-cam/crankcase ventilation system emotweni. Ukufaka ithangi lokubamba uwoyela (ikani) kuhloswe ukunciphisa inani lemihwamuko kawoyela ephinde ijikelezwe ekungeneni kwenjini.
Ukuphefumula kahle kwe-crankcase
Ngesikhathi sokusebenza okuvamile kwenjini yemoto, ezinye izihwamuko ezivela kusilinda zidlula emasongweni episton bese zehlela ku-crankcase. Ngaphandle kokungena komoya lokhu kungacindezela i-crankcase futhi kubangele izinkinga ezinjengokuntuleka kokuvalwa kweringi ye-piston kanye nezimpawu zikawoyela ezilimele.
Ukuze ugweme lokhu, abakhiqizi benza uhlelo lokungenisa umoya we-crankcase. Ekuqaleni lokhu kwakuvame ukusethwa okuyisisekelo lapho isihlungi sasibekwe phezulu kwekesi le-cam futhi ukucindezela nezihwamuko zingene emoyeni. Lokhu kuthathwe njengokungamukelekile njengoba kwavumela intuthu nenkungu kawoyela ukuthi ikhiphele emkhathini okwadala ukungcola. Kungase kudale izinkinga kubagibeli bemoto njengoba ikwazi ukudonselwa ngaphakathi emotweni, okuyinto evame ukungathandeki.
Cishe ngo-1961 kwasungulwa umklamo omusha. Lo mklamo uhambise i-crank breather ekungeneni kwemoto. Lokhu bekusho ukuthi umhwamuko nenkungu kawoyela kungashiswa kukhishwe emotweni nge-exhaust. Akukhona nje ukuthi lokhu kwaba mnandi kakhulu kubagibeli bezimoto kwakusho nokuthi inkungu kawoyela yayingadedelwa emoyeni noma ingene emgwaqeni uma kwenzeka kunezinhlelo zokungenisa umoya ezisalungiswa.
Izinkinga ezidalwe ama-crank breathers ahamba ngendlela
Kunezinkinga ezimbili ezingabangelwa ukuhambisa i-crank breather ohlelweni lokuthatha lwenjini.
Inkinga enkulu imayelana nokunqwabelana kwamafutha ngaphakathi kwamapayipi okuphuza kanye nokuphindaphindeka. Ngesikhathi sokusebenza okujwayelekile kwenjini i-blow-by eyeqile kanye nezihwamuko zikawoyela ezivela ku-crank case zivunyelwe ukungena ohlelweni lokuthatha. Inkungu kawoyela iyaphola futhi yendlale ingaphakathi lamapayipi okukhiphayo kanye nokuphindaphindeka. Ngokuhamba kwesikhathi lolu ungqimba lungakheka futhi udaka oluwugqinsi lunganqwabelana.
Lokhu kube kubi kakhulu njengoba kwethulwa uhlelo lwe-exhaust gas recirculation (EGR) ezimotweni zesimanje. Umhwamuko kawoyela ungaxubana negesi yokukhipha igesi esakazwa kabusha kanye nensiza ebuye inqwabelane kuma-nifold amaningi kanye namavalvu njll. Lolu ungqimba ngokuhamba kwesikhathi luyaqina futhi lujiye ngokuphindaphindiwe. Khona-ke izoqala ukuvala umzimba we-throttle, ama-swirl flaps, noma ngisho nama-valve okungenisa ezinjini ezijovwe ngqo.
Ukuba nenqwaba ye-sludge kungabangela ukusebenza okuphansi ngenxa yomphumela okhawulelayo ekugelezeni komoya enjinini. Uma i-buildup iba ngokweqile emzimbeni we-throttle ingabangela ukungenzi kahle njengoba ingavimba ukugeleza komoya ngenkathi i-throttle plate ivaliwe.
Ukufaka ithangi lokubamba (ikani) kuzonciphisa inani lomhwamuko kawoyela ofinyelela endaweni yokudonsa kanye negumbi lokusha. Ngaphandle komhwamuko kawoyela umule ovela kuvalvu ye-EGR ngeke ugxumeke kakhulu ekuthatheni okuzokwenza ukuthi intuthu ivaleke.
