Kugogodako ndi chiyani?
Kugogoda kwa injini sikutanthawuza chilichonse chabwino ndipo mwatsoka ndi chizindikiro chakuti tidzawononga ndalama zambiri posachedwa.
Kuti mukhale ndi ochepa mwa iwo momwe mungathere, m'pofunika kupanga matenda olondola.
Injini ndi makina ovuta kwambiri ndipo pali zovuta zambiri mmenemo. Chimodzi mwa zizindikiro zowonongeka ndikugogoda komwe sikufanana ndi phokoso la injini. Poyambitsa injini yozizira, phokoso la phokoso ndilokwera kwambiri kuposa pamene unityo ili. 
anatenthetsa ntchito kutentha. Izi ndizochitika ndi injini za dizilo, zomwe zimadziwika ndi chikhalidwe chochepa cha ntchito pambuyo poyambira. Izi nzabwinobwino ndipo musade nkhawa nazo. Komabe, pakapita masekondi angapo kapena angapo, kapena mpaka injini itatenthedwa, kugogoda kwachitsulo kumamveka pafupi ndi chivundikiro cha valve, izi zimasonyeza kuwonongeka kwa zonyamulira za hydraulic. Chifukwa cha izi chingakhalenso mafuta olakwika kapena mafuta omwe sanasinthidwe kwa nthawi yaitali. Kugogoda koteroko kumamveka ngakhale palibe kusintha kwa hydraulic. Ndiye muyenera kusintha ma valve clearances. Chochitikachi chimawononga pakati pa PLN 30 ndi 500, kutengera zovuta.
Tsoka ilo, zitha kuwoneka kuti chifukwa cha chivundikiro cha valve kugogoda ndi camshaft yowonongeka, kapena makamera omwe amatsegula ma valve. Wodzigudubuza watsopano ndi wokwera mtengo, kotero mutha kuyesa kubwezeretsa (pakati pa PLN 30 ndi 50 pa cam) kapena kugula yogwiritsidwa ntchito.
Kugogoda kwachitsulo kumatha kuchitikanso injini ikatentha. Ngati zichitika pansi pa katundu ndi liwiro lotsika la injini, ndiye kuti ndi kuyaka komwe kumapezeka mu injini yamafuta yomwe ikuyenda pamafuta otsika kwambiri kapena nthawi yoyatsira imayikidwa molakwika. Komanso pansi pa katundu, kaya injini ndi yotentha kapena ayi, tchire ndi pistoni zimadzimva. Phokosoli lidzakhala losasunthika komanso lomveka bwino komanso lomveka bwino, koma lidzazimiririka pamene musiya phazi lanu kuchoka pa gasi. Pini idzamveka pamwamba ndi projectiles pansi pa injini. 
Kuzindikira kumakhala kovuta kwambiri chifukwa cha phokoso lapamwamba lomwe limatulutsidwa ndi injini. Stethoscope idzakuthandizani kwambiri, zomwe mungathe kumvetsera injini.
Kuyendetsa nthawi kumatha kukhalanso phokoso. Unyolo wowonongeka umayambitsa chibwibwi. Osasintha unyolo nthawi yomweyo, chifukwa opareshoni yaphokoso imatha kuyambitsidwa ndi tensioner yowonongeka kapena kutsika kwamafuta ochepa kwambiri, zomwe zimakhudza kwambiri kuchuluka kwa kupsinjika kwa unyolo.
Phokoso losiyanasiyana limathanso kubwera kuchokera ku zida, ma tensioner bearings kapena ma V-lamba otayirira. Koma mawu awa ndi odziwika kwambiri, kotero makaniko abwino sayenera kukhala ndi vuto lozindikira bwino.
