Valve clearance kugadzirisa
Mumotokari zhinji nhasi, unogona kukanganwa nezvezvinhu zvakadai sekugadzirisa kuomesa valve. Vazhinji, asi kwete vese.
Kune zvakare magadzirirwo anoda periodic clearance cheki.
Pakati pemotokari makore akati wandei uye anopfuura makore gumi, dzinenge injini dzese dzinoda kugadziriswa kwevharuvhu.
Valve clearance inodiwa pakushanda kwakaringana kweinjini, nekuti nekuda kwekuwedzera kwekupisa kwezvinhu uye nekupfeka kwakarongeka kwekubatana. 
zvinhu, zvinodikanwa kuve nechokwadi chekushanda kwakaringana kweinjini, i.e. mavharuvhu akavharwa zvakasimba. Zvisinei, gaka iri rinofanira kuva neukoshi hwakakodzera. Kunyanya kana kushoma zvakanyanya kunokanganisa hupenyu hurefu hweinjini uye kushanda kwakakodzera. Makapu akakura anokonzera kuwedzera kwesimbi ruzha uye kukurumidza kupfeka pamavharuvhu, camshaft lobes uye maoko e rocker. Kune rimwe divi, kudiki kana kusava nemvumo kunogona kutungamirira kukuvhara kwevhavha isina kukwana uye kudonha kwekumanikidza mukamuri yekupisa. Kana mavhavha asingabatani nezvigaro zvevhavha, hazvizokwanisi kutonhora pasi, kutonhora kwavo kuchakwira uye, semugumisiro, plug yevhavha inogona kukuvadzwa (yakapiswa).
Mamiriro ezvinhu aya achaitika nekukurumidza paLPG nekuti tembiricha yekupisa yakakwirisa zvishoma pane peturu. Uyezve, kana gasi rakagadzirwa zvakanyanya zvishoma, kupisa kwekupisa kunokwira zvakanyanya. Kugadzirisa injini kuchadhura. Uye izvi zvose zvinogona kudziviswa nekugadzirisa zvakarongeka mavharuvhu. Mutengo wekuita uku idiki zvakanyanya maererano nemutengo wekuzotevera kugadziridzwa kweinjini.
Mune mota zhinji dzakagadzirwa izvozvi, mavharuvhu emvumo anodzorwa nema hydraulic lifters. Ndizvo zvimwe chete nedzinenge dzese mota nyowani. Honda chete neToyota havana chokwadi nezve hydraulics uye vachiri kutarisa nguva nenguva kuti vaone mapeji. 
vharafu. Mota dzechikuru dzinosiyana, asi zvinogona kuitwa zvakazara kuti kana injini ine mavharuvhu mana pacylinder, inogona kunge inodzorwa ne hydraulically. The kunze vamwe Ford, Nissan uye, hongu, Honda uye Toyota injini. Kune rimwe divi, kana injini ine mavharuvhu maviri pacylinder, iwo anokwirisa angangoda kugadziridzwa. VW neOpel zvakasiyana pano. Mune injini dzemakambani aya, mavharuvhu aisada kugadziriswa kwenguva yakareba.
Kugadzirisa mavharuvhu pamotokari zhinji ibasa riri nyore. Zvese zvaunoda kuti uite kubvisa chivharo chevhavha uye zvese zvaunoda ndeye wrench uye screwdriver kugadzirisa. Zvisinei, mune mamwe mamodheru (Toyota), kugadzirisa kwakaoma uye kunoda ruzivo rwakakosha uye maturusi anokosha, sezvo camshafts, uye saka bhandi renguva, rinofanira kubviswa.
Kuwanda kwekugadzirisa gap kunosiyana zvikuru. Mune dzimwe motokari, inofanira kuitwa pane imwe neimwe yekuongorora, uye mune dzimwe, chete kana uchitsiva bhanhire renguva, i.e. kupararira kunobva ku10 kusvika ku100 zviuru. km. Kana injini iri kushanda pairi liquefied gasi, kugadziriswa kwevharuvhu kunofanira kuitwa kaviri kakawanda.
