Product Advantages

• Higher fuel efficiency: The advanced design by Cummins and the dedicated craftsmanship enable a fuel consumption of 20% lower than similar products in China.

• Strong power: The design of wastegate valve further improves the low-speed performance and brings about better power performance.

• Excellent reliability: The integrated design of cylinder block and cylinder head prevents the engine from leakage and reduces the amount of components by 40% compared with engines of same type, thereby greatly reducing the fault rate.

• Excellent cold start performance: The electric intake heater and the 6.6kW high-power starter completely improve cold start performance of the engine, and the engine has passed the extremely low temperature test under -36℃ in Mohe - the Arctic Village in China.
