Likarolo tse ka sehloohong ke cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel joalo-joalo. Kamore e sebetsang ea enjene e tukang ka hare ea piston e bitsoa cylinder, 'me bokaholimo ba silindara ke cylindrical. Piston e khutlisetsang ka har'a cylinder e hoketsoe ka ntlha e le 'ngoe ea molamu o hokahanyang ka phini ea piston,' me ntlha e 'ngoe ea molamu o hokahanyang e hokahane le crankshaft, e tšehetsoeng ke ho beha sekontiri sa cylinder mme e ka fetoloa e belehang ho etsa mochini o kopanyang oa crank.
