Pali chubu choyamwa pafupi ndi fyuluta ya mpweya. Chikuchitika ndi chiani?
Iyi ndi chubu mu crankcase ventilation system yomwe imatsogoleranso mpweya wotulutsa mpweya kupita kumalo ochulukirapo kuti uyake. Injini yagalimotoyo imakhala ndi makina opumira mokakamiza, ndipo injini ikathamanga, mpweya wina umalowa mu crankcase kudzera mu mphete ya pistoni. Ngati mpweya wochuluka ulowa mu crankcase, kuthamanga kwa crankcase kumawonjezeka, zomwe zidzakhudza pisitoni pansi, komanso zimakhudza kusindikiza kwa injini. Chifukwa chake, ndikofunikira kutulutsa mpweya uwu mu crankcase. Mipweya imeneyi ikatulutsidwa mwachindunji m’mlengalenga, imawononga chilengedwe, n’chifukwa chake akatswiri anapanga makina opumira mpweya wokakamiza wa crankcase. The crankcase mokakamiza mpweya dongosolo amalozera mpweya kuchokera crankcase kulowa mu manifold intake kuti alowenso mchipinda choyaka. Palinso mbali yofunika kwambiri ya crankcase ventilation system, yomwe imatchedwa olekanitsa mafuta ndi gasi. Mbali ina ya gasi yomwe imalowa mu crankcase ndi gasi wotuluka, ndipo gawo lina ndi nthunzi wamafuta. Cholekanitsa chamafuta ndi gasi ndikulekanitsa mpweya wotuluka kuchokera ku nthunzi yamafuta, zomwe zingapewe injini kuwotcha chodabwitsa chamafuta. Ngati cholekanitsa chamafuta ndi gasi chasweka, chimapangitsa kuti nthunzi yamafuta ilowe mu silinda kuti itenge nawo gawo pakuyaka, zomwe zimapangitsa injini kuwotcha mafuta, komanso kupangitsa kuti kuchulukidwe kwa kaboni muchipinda choyaka. Ngati injini iwotcha mafuta kwa nthawi yayitali, imatha kuwononga chosinthira chanjira zitatu.
