Injini esetyenzisiweyo yenye yezinto ezibiza kakhulu onokuzithenga kwiyadi yeemoto, kwaye kwezi ziphosiso zibiza kakhulu. Ukuba uyenza ngendlela echanekileyo, yeyona ndlela ilumkileyo — injini esetyenzisiweyo elungileyo ivamise ukubiza inxalenye nje yexabiso lentsha kubathengisi abasemthethweni.
Oko "ihlolwe" ikuthethayo ngenene
Xa iyadi isithi injini "ihlolwe", ngokuqhelekileyo kuthetha ukuba yavele yasebenza. Oku akuloluvavanyo olunzulu. Buza umthengisi ukuba yahlolwa njani, kwaye ucele ividiyo yokuqalisa isengaband’ ukuba kunokwenzeka.
Buza ngembali
Buza ukuba injini yavela kweyiphi imoto, yafika njani kwiyadi, kwaye yayihambe iikhilomitha ezingaphi. Impendulo ethi "asazi" enyanisekileyo ingcono kunempendulo egqibeleleyo kakhulu.
Uvavanyo ngaphambi kokuhlawula
Jika i-crankshaft ngesandla — kufuneka ihambe ngokulula. Jonga phantsi kwesivalo samafutha ukuba akukho nto enje ngobisi (oku kuthetha amanzi kumafutha — hamba). Ceba uvavanyo lwe-compression ukuba kunokwenzeka, ngakumbi kwi-diesel. Qinisekisa ukuba inombolo yenjini iyafundeka.
Ukulingana kulapho ukuthenga ngeliso elimfamekileyo kuphosakala khona
Imodeli enye idla ngokuba neenjini ezahlukeneyo ngexesha lokuveliswa. I-VIN (inombolo yokuchonga imoto) ibonisa ukuba yeyiphi injini efanelekileyo — kungekhona igama lemodeli kuphela.
Isishwankathelo
Thenga kubathengisi abanokukuvumela ubone injini isebenza, abaphendula ngokunyaniseka, kwaye banike imiqathango yewaranti ngokubhaliweyo. Phepha kwiinombolo ezicinyiweyo, amafutha anjengobisi, kunye namaxabiso aphantsi kakhulu ukuba abe yinyani.
