Cummins QST30-C1050 injini jakisoni wamagetsi ndi 12-silinda, v woboola pakati Madigiri 50, sitiroko 4, madzi utakhazikika jekeseni mwachindunji, supercharged intercooling injini zochokera The Japanese Komatsu SA12V-140 injini, anayamba kupanga mu 1988. amagwiritsidwa ntchito kwambiri m'magalimoto otayira migodi, zonyamula katundu ndi ma bulldozer ndi zida zina.Injini ya QST30 ndi mitundu ina ya injini, ndi makina olumikizira ndodo, makina ogawa gasi, dongosolo loperekera mafuta, dongosolo lopaka mafuta, dongosolo lozizirira ndi dongosolo loyambira.

Ntchito zamakina a injini yamafuta ndi zabwino zake

1.Dual RP39 Bosch mafuta mpope
2.Engine Electronic Control System
3.Kuchepetsa kugwiritsa ntchito mafuta, kupititsa patsogolo kuyankha mofulumira komanso kuchepetsa utsi wa utsi pansi pa ntchito zosiyanasiyana.
4.Cancel the mechanical throttle cable (electronic throttle)
5.Optimize injini ntchito makhalidwe
6.Amapereka machitidwe olamulira omwewo monga ena onse a banja la Quantum

Mawonekedwe ndi maubwino a pistoni zachitsulo

1.Adopt mapangidwe omwewo omwe amagwiritsidwa ntchito ndi Komatsu
2.Kuthamanga kwa silinda kwapamwamba kuposa ma pistoni a aluminiyamu
3.Kugwiritsa ntchito kuzungulira kumakulitsidwa kwambiri
4.Gwirani ntchito limodzi ndi cylinder liner kuti muthetse mavuto a cavitation

Ubwino wa pre-lubrication system

1.Pewani zolakwika pakukonza: Zimalepheretsa kuyambitsa makina pomwe kulibe mphamvu yamafuta, ndipo sikuyanika kuyambira.
2.Improve kukonzanso mkombero ndi gawo moyo
3.Kuchulukitsa kudalirika kwagalimoto ndi kukhazikika, kuchepetsa ndalama zogwirira ntchito
