This engine adopts a 6-cylinder inline layout, a 19.0L displacement, a rated power of 760 horsepower (567kW), and a maximum torque of 3084 N·m. The power output is strong and smooth, precisely matching the operating speed and digging force requirements of the XCMG XE1150 excavator. It can efficiently cooperate with the machine to complete heavy-duty mining, large-scale mining truck loading, and other operations, significantly improving the efficiency of mining operations.
Designed to address the harsh working environment of mines, characterized by high dust levels, high intensity, and frequent start-stop cycles, the engine features optimized structural design and protective performance. It employs a high-strength alloy cylinder block, integrated cylinder head, and a dual-stage filtration system to effectively resist dust corrosion, reduce the failure rate, extend service life and maintenance cycles, and minimize equipment downtime.
The engine is equipped with a modular common rail fuel system, resulting in low fuel consumption. Balancing economic efficiency and environmental friendliness in mining operations, it strictly meets the Stage III emission requirements for non-road applications, achieving low-pollution emissions without the need for complex aftertreatment devices. Furthermore, it is compatible with the XCMG XE1150 engine control system, enabling real-time monitoring of operating parameters, fault warnings, and convenient maintenance. This comprehensive approach fully adapts to the actual operational needs of mining, helping to improve both economic efficiency and operational safety.
