Advantages of DCEC QSZ13-C475-II Industrial Engine

  • Using Cummins XPI ultra-high pressure fuel injection system, the fuel injection pressure is up to 2400bar; through precise combustion control, the lowest specific fuel consumption can reach 186g/kW.h, and the low fuel consumption area is wide and more fuel-efficient.

  • Optimize the configuration of the whole machine, lighter weight and more compact structure, the maximum output power can reach 500 kilowatts, the power is surging.

  • Integral all-steel piston design, cylinder block and crankshaft made of high-strength materials, can withstand super-high explosion pressure of 230bar, rigorous component test verification, higher engine strength, and excellent reliability.

  • Adopt Cummins electronic control intelligent module to monitor the running status of the engine at any time, precisely control the fuel injection, so that the engine can also think.

  • No need for any cold start auxiliary device, easy to start at -15℃ ambient temperature; with auxiliary device can start at -30℃.

  • The engine adopts an optimized design of combustion chamber and high-mounted piston ring, four-valve structure, low cylinder head airway swirl ratio, high injection pressure fuel system, and almost zero smoke, achieving a perfect combination of emissions and economy.
