Advantages of DCEC QSZ13-G2-B G-Drive Engine

  • XPI ultra-high pressure fuel injection system is adopted, and the fuel injection pressure is up to 2400bar;

  • Through precise combustion control, the minimum specific fuel consumption can reach 186g/KW.h, and the low fuel consumption area is wide and more fuel-efficient.

  • 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.

  • Excellent overall configuration, lighter weight and more compact structure in similar products, the maximum output power can reach 500 kilowatts, and the power is surging.
