Kuipa kwa injini ya Hyundai D4BH
1.Ngakhale kuti injiniyo ili ndi mpope wodalirika wa jekeseni wa Bosch VE wa mtundu wogawa, mavuto omwe amapezeka kwambiri a injini za dizilo zotere amagwirizanitsidwa ndi kulephera kwa dongosolo la mafuta. Chifukwa chogwiritsa ntchito mafuta otsika kwambiri, magawo amakina a pampu yamafuta othamanga kwambiri amatha ndipo chipangizocho sichimayamba bwino pakatentha. Pachifukwa chomwecho, ma nozzles a jekeseni amasinthidwa.
2.Malinga ndi malamulo, lamba wa nthawi amasinthidwa makilomita 90,000 aliwonse, koma nthawi zambiri amaswa kale kwambiri. Zonsezi chifukwa zimafunika kukhwimitsidwa pa 30,000 km iliyonse, koma anthu ambiri amanyalanyaza bukuli. Komanso, lamba wa balancer shaft nthawi zambiri amathyoka ndiyeno amayamwa pansi pa lamba wanthawi, womwe umaswekanso. Ndibwino kuti nthawi zambiri zimangophwanya rocker.
3.Diesel a mzerewu sakonda kutenthedwa ndipo gasket imadutsa mwa iwo nthawi zambiri, ndipo m'malo mwa gasket sikokwanira, muyenera kugaya malo okwerera. Muzochitika zapamwamba kwambiri, ming'alu imawonekera pakati pa ma valve ndi kuzungulira prechambers. Choncho, mitu ya silinda ya injini zoterezi ndizosowa kwambiri komanso zodula.
4. Timalemba zotsalira zotsalira pamndandanda umodzi: mafuta amakwera nthawi zonse kuchokera ku zisindikizo zamafuta, nthawi zambiri amadula kiyi ya crankshaft, yomwe imayimitsa nthawi yomweyo kuyendetsa kwa zomata, ndipo ngakhale ndikuyenda motalika kwambiri pa liwiro lotsika, crankshaft imatha kuphulika. Ndipo musaiwale za kusintha kwa nthawi kwa valve chilolezo kapena iwo amangotentha.
