Gulu lamakono lama injini zamagalimoto limapangidwa makamaka ndi thupi, mutu wa silinda, chivundikiro chamutu cha silinda, cylinder liner, chivundikiro chachikulu ndi poto yamafuta. Msonkhano wa thupi la injini ndi bulaketi ya injini, yomwe ndi matrix opangira makina olumikizira ndodo, makina ogawa ma valve, ndi zigawo zazikulu za injini. Mutu wa silinda umagwiritsidwa ntchito kusindikiza pamwamba pa silinda ndikupanga chipinda choyaka pamodzi ndi korona wa pisitoni ndi khoma la silinda.

Mutu wa silinda umagwiritsidwa ntchito kusindikiza silinda ndikupanga chipinda choyaka moto. Mutu wa silinda umaponyedwa ndi jekete lamadzi, dzenje lolowera, dzenje lotulukira, dzenje la spark plug, bolt bolt, chipinda choyaka moto, ndi zina zambiri.

Chophimba cha silinda ndiye thupi lalikulu la injini, kulumikiza silinda iliyonse ndi crankcase yonse. Ndilo chimango chothandizira kukhazikitsa ma pistoni, ma crankshafts, ndi zina ndi zina.

Silinda gasket ili pakati pa mutu wa silinda ndi chipika cha silinda, ndipo ntchito yake ndikudzaza ma pores ang'onoang'ono pakati pa silinda ndi mutu wa silinda, kuonetsetsa kuti kusindikizidwa bwino pamalo olumikizirana, potero kuonetsetsa kusindikizidwa kwa chipinda choyaka moto ndikuletsa kutayikira kwa silinda. ndi kutayikira kwa jekete lamadzi.

Gulu lolumikizira pisitoni ndi gawo lotumizira injini, lomwe limatumiza kupsinjika kwa mpweya woyaka ku crankshaft, ndikupangitsa kuti izungulire ndikutulutsa mphamvu. Gulu lolumikizira pisitoni limapangidwa makamaka ndi pisitoni, mphete ya pistoni, pistoni ndi ndodo yolumikizira.

Ntchito yaikulu ya pisitoni ndi kupirira kupanikizika kwa mpweya woyaka ndi kutumiza mphamvu iyi ku ndodo yolumikizira kudzera pa piston kuti muyendetse crankshaft kuti izungulira. Kuphatikiza apo, pamwamba pa pisitoni, mutu wa silinda, ndi khoma la silinda pamodzi zimapanga chipinda choyaka moto. Pistoni ndi gawo lowopsa kwambiri mu injini yomwe imagwira ntchito, yokhala ndi mpweya komanso mphamvu zobwerezabwereza zomwe zimagwira ntchito.
