Kukho ityhubhu yokufunxa ecaleni kwesihluzo somoya. Kwenzeka ntoni?
Le yityhubhu ekwinkqubo yokungenisa umoya ye-crankcase eqondisa kwakhona igesi yokukhupha umoya kwi-intake manifold ukuze itshiswe. Injini yemoto inenkqubo yokungenisa umoya ephoqelelwe yi-crankcase, kwaye xa injini isebenza, igesi ethile iya kungena kwi-crankcase ngeringi yepiston. Ukuba igesi eninzi ingena kwi-crankcase, uxinzelelo lwe-crankcase luya kwanda, nto leyo eya kuchaphazela i-piston phantsi, kodwa ikwachaphazela nokusebenza kokuvala kwenjini. Ke ngoko, kuyimfuneko ukukhupha ezi gesi kwi-crankcase. Ukuba ezi gesi zikhutshwa ngqo emoyeni, ziya kungcolisa okusingqongileyo, yiyo loo nto iinjineli zayila inkqubo yokungenisa umoya ephoqelelwe yi-crankcase. Inkqubo yokungenisa umoya ephoqelelwe yi-crankcase iqondisa kwakhona igesi ukusuka kwi-crankcase ukuya kwi-intake manifold ukuze ikwazi ukungena kwigumbi lokutsha kwakhona. Kukwakho nenxalenye ebalulekileyo yenkqubo yokungenisa umoya ye-crankcase, ebizwa ngokuba yi-oil and gas separator. Inxalenye yegesi engena kwi-crankcase yi-exhaust gas, kwaye inxalenye yi-oil vapor. I-oil and gas separator yenzelwe ukwahlula igesi yokukhupha umoya kwi-oil steam, enokuthintela i-oil oil evuthayo kwinjini. Ukuba isihluli seoyile negesi siphukile, siya kubangela ukuba umphunga weoyile ungene kwisilinda ukuze ubandakanyeke ekutshisweni, nto leyo eya kubangela ukuba injini itshise ioyile, kwaye iya kukhokelela ekwandeni kokuqokelelwa kwekhabhoni kwigumbi lokutsha. Ukuba injini itshisa ioyile ixesha elide, inokubangela umonakalo kwi-three-way catalytic converter.
