Ukulungiswa kweenjini ze-Automobile ikakhulu kubandakanya ukutshintshwa kweevalvu, iipistoni, ii-cylinder liners, okanye iisilinda, iishafts zokusila, njl njl. Ngokomgangatho weevenkile ze-4S eziqhelekileyo, kufuneka zitshintshwe ngezixhobo ezixhasayo ezi-4, oko kukuthi, iipiston, iindandatho zepiston, iivalve, izitywina zeoyile yevalvu, izikhokelo zevalvu, iishingles ze-crankshaft, iishingles zentonga ezidibanisayo, amabhanti exesha, amavili acinezelayo.
Ukuba ikhonkco liphelelwe lixesha, kuyafuneka ukuba utshintshe ikhonkco lexesha, i-tensioner, ukongeza kwi-machining, umkhono we-cylinder, ishaft yokusila, i-conduit yoxinzelelo olubandayo, kodwa kuyafuneka ukuba utshintshe iphakheji yokulungisa, itywina langaphambili le-oyile egobileyo, itywina leoyile eligobileyo. , uphawu lweoli ye-camshaft, ipompo yeoli, i-valve yophando ngakumbi, njl., ngamanye amaxesha kufuneka kwakhona ukutshintsha izixhobo zangaphandle ezifana ne-clutch disc, njl. ukusebenza kwe-injini.
