Engine catalog
We supply 180+ new and remanufactured Cummins diesel engines, matched to your duty cycle by application. Construction and mining equipment - excavators, loaders, haul trucks, drills - runs on high-torque 4BT, 6BT, 6CT, KTA19 and KTA38 platforms. Marine propulsion and auxiliary generator sets use heat-exchanger-cooled, continuous-duty QSK and KTA series; pump and compressor drives take dedicated pump-drive and generator-drive ratings; truck and bus fleets get mid-range on-highway power. Every engine is nameplate-verified - we match the model and serial plate to your order - and load-tested before dispatch, with no-load and full-load runs documented. Remanufactured units follow Cummins reman standards on genuine cores. Stock is sourced direct from Dongfeng Cummins (DCEC) in Xiangyang; we quote against your nameplate photo and handle export crating. Tell us the model and duty and we will match the right engine.
