Products
（1）900kW~1200kW prime genset, for continuous and stable power supply.
（2）1000kW~1350kW standby genset, for reliable and fast standby power supply.
The application of HP common rail fuel injection system, four-valve, efficient turbocharged & intercooled technology, and Yuchai's combustion technology ensure low fuel consumption, low emission, excellent speed regulation performance, and fast and powerful load (5s).
One head for one cylinder, with a maintenance window on the side of the engine body, which is convenient for maintenance.
The engine body is made of high-strength materials, with an arc-reinforcing rib grid structure and a four-bolt main bearing structure, featuring high rigidity, low vibration, and low noise. The crankshaft is made of high-quality alloy steel by all-fiber extrusion forging, with shaft diameter and fillet quenching heat treatment, featuring wear resistance and long service life. World-class equipment and production technologies ensure stable and reliable quality. Meet the genset performance grade G3 requirements.
