Hariho ubwoko bubiri bwimpeta ya piston yo kuvugurura moteri:ingano isanzwe n'ubunini bwagutse. Tugomba guhitamo impeta ya piston dukurikije ubunini bwa silinderi yabanjirije. Niba impeta ya piston yubunini butari bwo yatoranijwe, ntishobora gukwira, cyangwa ikinyuranyo hagati yibice ni kinini cyane. Ariko muri iki gihe ibyinshi muri byo bifite ubunini busanzwe, bike muri byo byagutse.

Kugenzura elastique yimpeta ya piston:Ubworoherane bwimpeta ya piston nimwe mubintu byingenzi kugirango tumenye neza silinderi. Niba elastique ari nini cyane cyangwa nto cyane, ntabwo ari byiza. Igomba kuba yujuje ibyangombwa bya tekiniki. Ikizamini cya piston impeta ikoreshwa muburyo bwo kumenya. Mubikorwa, muri rusange dukoresha ikiganza kugirango ducire urubanza hafi, mugihe cyose ridafunguye cyane, rushobora gukoreshwa.

Kugenzura urumuri rworoshye rwa piston nimpeta ya silinderi:Kugirango hamenyekane ingaruka zifunga impeta ya piston, hejuru yinyuma ya piston hasabwa kuba uhuza nurukuta rwa silinderi ahantu hose. Niba urumuri ruto ari runini cyane, aho uhurira nimpeta ya piston ni nto, bishobora guhita bitera guhitanwa na gaze cyane no gukoresha amavuta menshi. Hano hari ibikoresho byihariye byo kumenya urumuri rwa piston. Ibisabwa muri rusange ni: nta gucana urumuri rwemewe muri 30 ° yumutwe wanyuma wimpeta ya piston, kandi ntibirenze bibiri byoroheje byemewe kumpeta imwe ya piston. Inguni yo hagati ihuye ntigomba kurenga 25 °, inguni rusange ihuye nuburebure bwurumuri arc kumpeta imwe ya piston ntigomba kurenga 45 °, kandi icyuho cyo kumurika ntigomba kurenga 0.03mm. Niba ibisabwa haruguru bitujujwe, ugomba kongera guhitamo impeta ya piston cyangwa gusana silinderi.

Ni ngombwa kumenya ko mbere yuko impeta ya piston ishyirwaho, ni ngombwa kumenya niba umurongo wa silinderi nawo ushyizwemo chrome.Niba hejuru yimpeta ya piston na silinderi yashizwemo chrome, biroroshye kubyara phenomenon ya Cylinder amanota.
