Urusaku rudasanzwe muri silinderi ya moteri rushobora kuvugwa muri make nkijwi rya piston ikomanga, piston pin ikomanga, piston hejuru ikubita umutwe wa silinderi, piston hejuru ikubita, impeta ya piston ikomanga, gukubita valve, na silinderi ikomanga.

Ijwi ridasanzwe ryigice cya piston kirimo cyane cyane amajwi ya percussion yicyuma cyimpeta ya piston, ijwi risohoka ryumwuka wimpeta ya piston nijwi ridasanzwe riterwa no kubika karubone nyinshi.

(1) Ijwi ryikubita ryicyuma cya piston. Nyuma ya moteri imaze igihe kinini ikora, urukuta rwa silinderi rwarashaje, ariko ahantu igice cyo hejuru cyurukuta rwa silinderi ntaho gihurira nimpeta ya piston hafi ya yose igumana imiterere nubunini bwa geometrike, bigatera intambwe kurukuta rwa silinderi. Niba igitereko gishaje cya silinderi cyakoreshejwe cyangwa igitereko gishya gisimburwa ni gito cyane, impeta ya piston ikora izahura nintambwe zurukuta rwa silinderi, byumvikane neza. Niba umuvuduko wa moteri wiyongereye, urusaku rudasanzwe ruziyongera uko bikwiye. Mubyongeyeho, niba impeta ya piston ivunitse cyangwa ikinyuranyo hagati yimpeta ya piston nigitereko cyimpeta nini cyane, bizatera kandi ijwi rikomanga cyane.

(2) Ijwi ryimyuka iva mumpeta ya piston. Imbaraga za elastike yimpeta ya piston iracika intege, icyuho cyo gufungura ni kinini cyane cyangwa gufungura hejuru, kandi urukuta rwa silinderi rufite ibinono, nibindi, bizatera impeta ya piston kumeneka. Uburyo bwo gusuzuma ni uguhagarika moteri mugihe ubushyuhe bwamazi ya moteri bugeze kuri 80 ℃ cyangwa hejuru. Muri iki gihe, shyiramo amavuta ya moteri make kandi asukuye muri silinderi, hanyuma utangire moteri nyuma yo kunyeganyeza igikonjo inshuro nke. Niba bibaye, dushobora kwemeza ko impeta ya piston isohoka.

(3) Ijwi ridasanzwe ryo kubika karubone ikabije. Iyo hari ububiko bwinshi bwa karubone, urusaku rudasanzwe ruva muri silinderi nijwi rikarishye. Kuberako ububiko bwa karubone butukura, moteri ifite ibimenyetso byo gutwika imburagihe, kandi ntibyoroshye guhagarara. Ishirwaho ryimyuka ya karubone kumpeta ya piston ahanini iterwa no kubura kashe iri hagati yimpeta ya piston nurukuta rwa silinderi, icyuho cyo gufungura cyane, gushiraho impeta ya piston, guhuza ibyambu byimpeta, nibindi, nibindi, bitera amavuta yo kwisiga kunyura hejuru hamwe nubushyuhe bwo hejuru hamwe na gaze yumuvuduko mwinshi kunyura hepfo. Igice cy'impeta kirashya, gitera imyuka ya karubone ndetse no kwizirika ku mpeta ya piston, bigatuma impeta ya piston itakaza ubukana bwayo n'ingaruka zo gufunga. Mubisanzwe, iri kosa rirashobora kuvaho nyuma yo gusimbuza impeta ya piston nibisobanuro bikwiye.
