Ukulungiswa kweenjini ze-Automobile ikakhulu kubandakanya ukutshintshwa kweevalvu, iipistoni, ii-cylinder liners, okanye iisilinda, i-shafts yokusila, njl njl. Ngokomgangatho weevenkile eziqhelekileyo ze-4S, kufuneka zitshintshwe ngezixhobo ezi-4 ezixhasayo, oko kukuthi, iipistons, amakhonkco episton, iivalve, izitywina zeoyile yevalvu, izikhokelo zevalve, iishingles ze-crankshaft, iishingles zentonga ezidibanisayo, amabhanti exesha, amavili acinezelayo.
Ukuba ikhonkco liphelelwe lixesha, kuyafuneka ukuba utshintshe ikhonkco lexesha, i-tensioner, ukongeza kwi-machining, i-cylinder sleeve, i-shaft yokusila, i-conduit yoxinzelelo olubandayo, kodwa kufuneka 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.
