Enwere tube mmiri n'akụkụ nzacha ikuku. Kedu ihe na-aga?
Nke a bụ tube dị na crankcase ventilashion nke na-emegharị gas na-ekpocha ọkụ na ebe a na-eri ihe maka combustion. The engine nke ụgbọ ala nwere a crankcase mmanye ventilashion usoro, na mgbe engine na-agba ọsọ, ụfọdụ gas ga-esi na crankcase mgbanaka piston. Ọ bụrụ na nnukwu gas na-abanye na crankcase, nrụgide nke crankcase ga-abawanye, nke ga-emetụta piston ala, ma na-emetụtakwa arụmọrụ akara nke engine. Ya mere, ọ dị mkpa ikpochapụ gas ndị a na crankcase. Ọ bụrụ na a na-ebupụ ikuku ndị a ozugbo n'ikuku, ọ ga-emetọ gburugburu ebe obibi, ọ bụ ya mere ndị injinia ji chepụta usoro ikuku crankcase mmanye. Igwe ikuku na-amanye ventilashị na-atụgharị gas si na crankcase n'ime ebe a na-eri ihe ka o wee banye n'ime ụlọ ọkụ ọzọ. E nwekwara akụkụ dị mkpa nke usoro ikuku crankcase, nke a na-akpọ mmanụ na gas separator. Akụkụ nke gas na-abanye na crankcase bụ gas na-ekpochapụ, akụkụ ya bụkwa vapo mmanụ. Ihe nkewa mmanụ na gas bụ ikewapụ gas na-ekpochapụ site na uzuoku mmanụ, nke nwere ike izere ihe ọkụkụ mmanụ na-ere ọkụ. Ọ bụrụ na onye na-ekewa mmanụ na gas agbajiri agbaji, ọ ga-eme ka uzuoku mmanụ banye na cylinder iji sonye na combustion, nke ga-eme ka engine na-ere mmanụ ọkụ, ọ ga-edugakwa n'ịba ụba nke mkpokọta carbon n'ime ụlọ combustion. Ọ bụrụ na injin ahụ na-ere mmanụ ruo ogologo oge, ọ nwere ike imebi ihe ntụgharị catalytic ụzọ atọ.
