Mune mvura mufirita yemhepo. Mune mvura here muinjini?
Kana firita remhepo razara nemvura, usaedza kutangazve. Nekuti mota inofamba-famba, mvura inopfuudzwa ichienda kunzvimbo inopindwa injini, yekutanga ichipinda mufirita remhepo, dzimwe nguva inotungamira zvakananga kunzvimbo inomira injini. Asi mvura zhinji yapinda mufirita remhepo, ichipinda muinjini, kutangazve kuchatungamira zvakananga kukuvara kweinjini, inofanira kunge iri nguva yekutanga kubata sangano rekugadzirisa kuti rirapwe.
Kana injini ikamira, ramba uchitanga kechipiri, mvura inozopinda zvakananga mu cylinder kuburikidza nemhepo inopinzwa, gasi rinogona kumanikidzwa asi mvura haigoni kumanikidzwa. Saka, kana crankshaft ikasundira tsvimbo inobatanidza kudivi rekumanikidzwa kwepiston, mvura haigoni kumanikidzwa, simba guru rekuita rinotungamira pakukombama kwetsvimbo inobatanidza, musiyano musimba retsvimbo inobatanidza, vamwe vachaona nemaziso kuti yakombama. Mamwe mamodheru anogona kunge aine deformation diki, kunyangwe mushure mekubuda kwemvura, anogona kutanga zvakanaka uye injini inomhanya zvakanaka. Asi mushure mekutyaira kwenguva yakati, deformation ichawedzera. Pane kukotama kwakakomba kwetsvimbo inobatanidza, zvichikonzera njodzi yekuputsika kwe cylinder block.
