Product Advantages
• Higher fuel efficiency:
The advanced design by Cummins and the dedicated craftsmanship enable a fuel consumption of 20% lower than similar products.
• Strong power:
The design of waste gate 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 leaking 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 extreme low temperature test under -36℃ in Mohe – the Arctic Village in China.
