Key Features
- 6BG1 mechanical pump structure with fewer electronic components, stable operation under high dust construction sites and low daily maintenance cost
- 6HK1 intercooled turbo and common rail fuel system realize sufficient low-speed torque, reduce black smoke and cut comprehensive fuel consumption by 12% compared with old mechanical engines
- High strength cast iron cylinder block with replaceable wet cylinder liner, convenient single cylinder overhaul without disassembling whole engine
- Dual series cooling water channel design effectively control operating temperature during long-hour full-load mining and transportation operation
- Unified standard mounting hole layout for excavator and truck variants, direct bolt-on replacement without frame modification save on-site assembly labor
- Independent lubricating oil filter circuit reduce impurity wear to crankshaft and connecting rod, extend engine overhaul cycle
