Camshaft: Naqshadaynta kambuyuutarku waxay si sax ah u xakameyn kartaa waalka iyo waqtiga duritaanka, iyo astaanta kamaradda la hagaajiyay waxay yarayn kartaa xoogga saameynta waxayna hagaajin kartaa isku halaynta iyo adkeysiga.
Crankshaft: shafka isku dhafan ee ka samaysan bir been abuur ah oo aad u sareysa.Habka adkaynta soo-jiidashada ee fillet iyo joornaalku waxay hubin karaan awoodda daalka sare ee shafka.
