Enjene ea mochini o tukang ka hare e sebetsa joang?
Pelo ea enjene ea combustion (ICE) e nang le molamu o sututsang ke crankshaft. Lithapo li hokahanya li-piston tsa enjene le li-journals tsa crankshaft. Crankshaft e leka-lekane ka ho lekana ka boima ba'mele ka lehlakoreng le fapaneng la koranta e 'ngoe le e' ngoe ho netefatsa hore ha e potoloha haholo ka motsotso (RPM) enjene e tsitsitse. Ha crankshaft e ntse e potoloha e sutumetsa lithupa tse hokahantsoeng le li-piston holimo le tlaase. Ka pel'a crankshaft ho na le gear, gear hangata e hokahane ka ketane ho camshaft. Haeba crankshaft ke pelo ea enjene, camshaft ke boko ba enjene. Kamshaft e etsa qeto ea hore na ho lokela ho buloa le ho koaloa li-valve tse lumellang moea le peterole hore li kene ka har'a silindara ka seng' me li ntše mosi o tsoang ka har'a silindara. Kamshaft ke shaft e tsamaeang ka bolelele ba enjene'me e na le li-lobes ho eona, li-cylinders tse nyenyane tsa tšepe tse bitsoang li-lifter li palama li-lobes tsena' me li kopantsoe le lithupa tse sutumetsang, lithupa tse sutumetsang li kopantsoe le li-rocker tse tsamaeang ka morao le ho bula le ho koala li-valve lihloohong tsa silindara. Li-valve li teng lihloohong tsa silindara tse holim'a lisilindara tseo li-piston li leng ho tsona. Ha li-piston li ntse li potoloha, valve (e khannoang ke camshaft) e bula ho tlisa mafura ka silindara, ha valve e koala tlhase e tsoang ho spark plug, e hotetsa mafura a bakang ho phatloha ho hoholo ho sutumetsang silindara fatše, valve ea bobeli ea buleha ho lumella mosi o tsoang ho phatloho e nyane ho tsoa enjene. Sena le sona se etsa hore crankshaft e potolohe, se sutumelletsa piston e 'ngoe holimo moo mokhoa ona o tsoelang pele. Mochine o kenang moea ka har'a enjene o tšoana le matšoafo a enjene, o hema moea o tsoang sepakapakeng'me o o kopanya le palo e nepahetseng ea peterole ho etsa hore ho be le ho phatloha ho hoholo ka har'a silindara. Nako eo moea, peterole, le tlhase li romelloang ka eona ke ea bohlokoa haholo haeba li sa tsamaee ka tekanyo e fokolang haholo, enjene e ke ke ea sebetsa ho hang.
