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, kupanikizika 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 apanga makina opumira mpweya wokakamiza wa crankcase.The crankcase mokakamizidwa mpweya mpweya dongosolo amalozera gasi 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 mafuta ndi gasi ndikulekanitsa mpweya wotuluka kuchokera ku nthunzi yamafuta, zomwe zingapewe injini kuyaka chodabwitsa chamafuta.Ngati cholekanitsa chamafuta ndi gasi chasweka, chimapangitsa kuti nthunzi yamafuta ilowe mu silinda kuti itenge nawo gawo pakuyaka, zomwe zimapangitsa kuti injini iwotche mafuta, komanso zimapangitsa kuti pakhale kuchuluka kwa kaboni m'chipinda choyaka moto.Ngati injini yayaka mafuta kwa nthawi yayitali, imatha kuwononga chosinthira chanjira zitatu.
