Product Advantages
  • The advanced Cummins XPI ultra-high pressure fuel injection system with injection pressure up to 2400 bar offers a minimum fuel consumption of 186g/kW·h, wider economic fuel consumption range and more fuel saving through precise combustion control.

  • Excellent engine configuration, lighter-weight and compact structure among similar products, and extraordinary performance with maximum output power of 500 kW.

  • The integral steel piston and the high-strength cylinder and crankshaft that can withstand 230 bar ultra-high burst pressure, harsh component test verification, higher engine strength, and excellent reliability.

  • The cutting-edge Cummins electronic control intelligent module consistently monitors the engine’s running state and precisely controls fuel injection, empowering the engine to “think”.

  • Easy start-up at -15°C ambient temperature without any cold-start assistance systems. Start up at -30°C with auxiliary systems.

  • The engine is a perfect combination of emissions and economy with optimized combustion chamber and high piston ring, advanced four-valve structure, low airflow-vortex ratio at cylinder head, high injection pressure fuel system, and near-zero smoke.

  • With advanced design, the engine gains maximal power per liter, which is up to 38.5 kW / liter.

  • The three-stage filter ensures balanced particle dispersion, protects main components of the fuel system and maximizes engine life.

  • The electronic control system intelligently switches to operation modes according to the environment and operating conditions. It has self-diagnosis, alarm and remote monitoring functions.

  • The mature intelligent electronic control technology improves the overall performance of the engine. The engine specifications can be customized according to application requirements.
