    Air-to-air cooling technology ensures more sufficient air intake and better fuel economy.

  • Compact, easy to maintain

    Replaceable wet cylinder liners , cooling effect , easy to replace.

    All models parts versatility , high degree of serialization , and easy maintenance.

    Block and head are taking a built-in pressure lubricants Road , compact , low failure rate

  • Advanced design and reliable performance

    Cylinder block: made of high-strength alloy cast iron, with good rigidity, low vibration and low noise.

    Cylinder head: Four valves per cylinder design, optimized air/fuel mixture ratio, effectively improving combustion and emissions; two cylinders and one head, easy maintenance.

    Camshaft: The large-diameter camshaft can withstand higher loads. The new design can accurately control the valve and injection timing. The optimized cam profile can reduce the impact force and improve the reliability and durability.

    Crankshaft: The integral crankshaft is made of high-strength forged steel. The induction hardening process of fillet and journal can ensure higher fatigue strength of the crankshaft.

    Piston: Using the latest aluminum alloy casting technology, the design of ω-shaped head and barrel-shaped skirt can compensate for thermal expansion and contraction to ensure a good fit.

Premium performance | Cummins diesel engine N series

  • Overview of Cummins Engine N Series NT & NTA
  • From a series that is service-proven through millions of hours of operation in some of the world's most demanding applications, the NT855 has been engineered to handle higher injection pressures, with redesigned overhead arrangement, pistons, crankshaft and camshaft. A gear train with high contact ratio spur gears also eliminates unwanted thrust loads and reduces noise.

    In line with the rest of the NT family, wide-ranging benefits including fuel efficiency, low oil consumption, reliable long life, high power and durability.

  • Mature products, well-known all over the world
  • Wide range of applications: Since Cummins entered China in 1975, N series engines have been widely used in construction machinery, heavy-duty vehicles, power generation, ship power and other fields

    High reputation: As one of the main models of the Cummins family, the N series engine has won high recognition from customers in various fields with strong power, ultra-low fuel consumption, high reliability and low maintenance costs.

    Technology upgrade: The BCIII design of the large camshaft, air-to-air cooling, slow start and other technologies have further improved the engine's reliability, power, fuel economy and emissions. The electronic injection technology being jointly developed with Cummins will further strengthen the leading position of the N series engine in China's high-horsepower engine manufacturing industry.
