Advantages of DCEC QSC8.3-C260-30 Industrial Engine

  • Advanced design, exquisite manufacturing technology, reliable and durable, suitable for high-strength and heavy-duty operations under severe working conditions.

  • Using ultra-high pressure fuel pump, burning more fully under high fuel injection pressure, less energy loss, strong power, strong fuel adaptability, and lower emissions.

  • Adopt Holset supercharger with integral wastegate valve, low-speed responsiveness and strong power.

  • Integral cylinder design, the number of parts is about 25% less than similar products, the failure rate is lower, and the maintenance is more convenient.

  • The cylinder liner adopts a platform mesh honing design and a corrosion-resistant high-nickel cast iron piston, which greatly reduces oil loss, enhances durability, and has a longer service life.

  • Advanced design, the engine power-to-liter ratio is larger, up to 23.4KW/L.
