Ukulungiswa kwe-injini yemoto ikakhulu kubandakanya ukutshintshwa kweevalvu, iipistoni, ii-cylinder liners, okanye iisilinda, iishafti zokusila, njl njl. Ngokomgangatho weevenkile ze-4S jikelele, kufuneka zitshintshwe ngezixhobo ezixhasayo ezi-4, oko kukuthi, iipistons, amakhonkco episton, iivalvu, izitywina zeoli yevalve, izikhokelo zevalve, i-crankshaft, i-crankshaft yokudibanisa i-timing rocket. amavili.
Ukuba ikhonkco liphelelwe lixesha, kuyimfuneko ukutshintsha ikhonkco lexesha, i-tensioner, ukongeza kwi-machining, i-cylinder sleeve, i-shaft yokusila, i-conduit yoxinzelelo olubandayo, kodwa kufuneka kwakhona ukubuyisela iphakheji yokulungisa, itywina le-oyile eligobileyo, itywina le-oyile egobileyo, i-oyile ye-camshaft, impompo yeoli, i-valve yophando engaphezulu, njl. njl. buyisela iindawo ezingaqinisekanga ukulungisa i-injini ukuqinisekisa ukusebenza kwe-injini.
