Ibice byimodoka nibicuruzwa bigize buri gice cyimodoka muri rusange kandi ikorera imodoka.Hariho ubwoko bwinshi bwimodoka, hamwe niterambere ryimibereho yabantu, abantu bakoresha imodoka nabo bariyongera, kandi isoko ryibice byimodoka bigenda byiyongera.Mu myaka yashize, abakora ibinyabiziga nabyo biratera imbere byihuse.Icyambere, moteri ya silinderi yo gufunga ikizamini
Hariho ibintu birindwi bigira ingaruka ku gufunga silinderi, cyane cyane kwambara silinderi, kwangiza impeta ya piston, kwambara piston, kwangiza intebe ya valve, kwambara icyerekezo cya valve, kwangirika kwa gaze ya silinderi, gukuraho valve nibindi bintu byikibazo.
Nubuhe buryo busanzwe bwo gusuzuma?Umuvuduko wingenzi wibipimo bya silinderi, umuyoboro wa gazi ya crankcase, kumeneka kwa silinderi nigipimo cyo kumeneka, gufata imiyoboro ya vacuum, itsinda rya piston ya silinderi kubera kwambara gukabije guterwa no gupima kunyeganyega kudasanzwe, kwambara crankcase kwambara ni kugena ibirimo ibice.
Kugirango hapimwe igitutu cyo guhunika silinderi, ahanini ni igitutu kumpera ya compression ya moteri enye.Bitewe numuvuduko wa silinderi hamwe nubukonje bwamavuta hamwe nitsinda rya piston ya silinderi, guhindura imikorere ya valve nibyo, gufunga padi ya silinderi nibindi bintu, bityo, mugihe upimye umuvuduko wa moteri ya moteri, urashobora gusuzuma Ikidodo c'itsinda rya piston ya silinderi, niba impeta ya piston, valve, kashe ya silinderi ari byiza, noneho gukuraho valve bigomba kuba bikwiye.
