Mvura iri mumotokari yemvura inofashaira, inofanira kutanga yadzika, yozotyaira mota padivi pemugwagwa, usamhanye kudzima injini, nekuti tembiricha yemvura yakawandisa, zvinozoita kuti piston, mudhuri wesimbi, cylinder, crankshaft uye kumwe kupisa kwakanyanya, mafuta aite mutete, orasa lubrication. Usadira mvura inotonhora painjini kana uchitonhodza, izvo zvinogona kuita kuti silinda yeinjini iparare nekuda kwekutonhodza kamwe kamwe. Mushure mekutonhodza, pfekai magirovhosi, uye wobva wawedzera chidimbu chejira rakanyorova pavhavha yetangi, zvinyoronyoro sunungura chivharo chetangi kuti uvhure mukaha diki, wakadai semhute yemvura inoyerera zvishoma nezvishoma, tangi kudzvanywa pasi, wedzera mvura inotonhorera kana antifreeze. Yeuka kubhadhara kuchengetedzwa panguva iyi, chenjerera kupisa.
