Product Advantages

• With advanced design and exquisite manufacturing process, the engine features high reliability and durability, adaptable to high-strength and heavy-duty operations under severe working conditions.

• High-pressure fuel pump enables complete combustion under high injection pressure, featuring low energy loss, strong power, high fuel adaptability and lower emissions.

• Holset supercharger with integral wastegate offers low-speed response and dynamic performance.

• With integral cylinder design, parts are about 25% less than similar products, featuring lower failure rate and easier maintenance.

• The cylinder liner adopts plateau honing cross hatch and corrosion-resistant high nickel cast iron piston, which significantly reduces engine oil loss and improves durability and service life.

• With advanced design, the power per liter is increased up to 23.4 kW / liter.

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