Izakhiwo ezahlukene.
1. I-Crankshaft: Iyingxenye ebaluleke kakhulu enjinini.
2. I-Camshaft: Iyingxenye yenjini yepiston.
Izimiso ezahlukene.
1. I-Crankshaft: I-crankshaft ingaphansi kwemithelela ehlanganisiwe yamandla amaphakathi wesisindo esiphendukayo, amandla ashintshayo egesi e-inertia kanye namandla aphindaphindayo e-inetia, okwenza i-crankshaft ibe ngaphansi kokugotshwa kanye nemithwalo ye-torsional.
2. I-Camshaft: Ijubane layo lisephezulu kakhulu. I-camshaft ivamise ukwakhiwa ngensimbi-yekhwalithi ephezulu ye-carbon steel noma i-alloy steel, futhi ingasakazwa nge-alloy cast iron noma i-ductile iron. Ijenali kanye nezindawo zokusebenza zekhamera ziyapholishwa ngemva kokwelashwa kokushisa.
Imisebenzi ehlukene.
1. I-Crankshaft: Ithwala amandla adluliswa kusuka ku-rod yokuxhuma, futhi iyiguqule ibe yi-torque ephumayo nge-crankshaft futhi iqhube ezinye izesekeli enjinini ukuze zisebenze.
2. I-Camshaft: Ilawula ukuvulwa nokuvalwa kwevalvu. Nakuba i-camshaft izungeza kuhhafu wejubane le-crankshaft enjinini-ye-stroke emine (enjinini-ye-stroke ezimbili izungeza ngesivinini esifanayo ne-crankshaft), ngokuvamile isashesha kakhulu futhi kufanele imelane ne-torque eningi.
