At a glance
The 12M55NG comes from an original Weichai diesel engine supplier and is built as a V-type, single-point injection, water-cooled, four-stroke, turbocharged and intercooled, pilot ignition unit, with 65.65 L displacement. Rated output spans 1716–2333 kW. Peak torque reaches 10014 N·m. It is supplied to meet No Emission Requirement emission requirements. Typical duty is rigid mining dump truck service.
Product Overview
V-type, 12 cylinders, four-stroke, turbocharged, water-air intercooled; displacement 65.7 L, rated power up to 1716 kW at a rated speed of 1800 r/min, maximum torque / speed 11700 (N·m) / 1400 (r/min).
Product Advantages
- Lower noise than the diesel engine.
- Adaptive correction strategies for ambient humidity and gas quality; precise boost-pressure control gives stable power output at ±50°C.
- A high-output gas engine for large mining trucks, with the same interfaces as the diesel engine.
