Kuneshubhu lokumunca eduze kwesihlungi somoya. Kwenzakalani?
Leli ishubhu kuhlelo lokungenisa umoya we-crankcase eliqondisa kabusha igesi yokukhipha umoya endaweni eningi yokusha ukuze isha. Injini yemoto ine-crankcase ye-ventilation system ephoqelelwe, futhi lapho injini isebenza, enye igesi izongena ku-crankcase ngeringi ye-piston. Uma igesi eningi ingena ku-crankcase, ukucindezela kwe-crankcase kuzokhuphuka, okuzophazamisa i-piston phansi, kodwa futhi kuthinte ukusebenza kokuvala kwenjini. Ngakho-ke, kuyadingeka ukukhipha la magesi ku-crankcase. Uma la magesi ekhishwa ngokuqondile emkhathini, azongcolisa indawo ezungezile, yingakho onjiniyela basungula uhlelo lokungenisa umoya oluphoqelelwe nge-crankcase. Isistimu yokungenisa umoya ephoqelekile ye-crankcase iqondisa kabusha igesi esuka ku-crankcase iye endaweni eningi yokudonsa ukuze ikwazi ukungena ekamelweni elivuthayo futhi. Kukhona futhi ingxenye ebalulekile yesistimu yokukhipha umoya we-crankcase, ebizwa ngokuthi isihlukanisi sikawoyela negesi. Ingxenye yegesi engena ku-crankcase igesi ephumayo, futhi ingxenye umhwamuko kawoyela. Isihlukanisi sikawoyela negesi siwukuhlukanisa igesi ephumayo nesitimu sikawoyela, okungagwema isimo sikawoyela esivuthayo. Uma isihlukanisi samafutha negesi siphukile, kuzokwenza ukuthi i-steam yamafutha ingene ku-cylinder ukuze ibambe iqhaza ekushiseni, okuzokwenza injini ishise amafutha, futhi kuzoholela ekwandeni kokuqoqwa kwekhabhoni ekamelweni lokushisa. Uma injini ishisa uwoyela isikhathi eside, ingase ibangele umonakalo kusiguquli se-catalytic esinezindlela ezintathu.
