Performance characteristics of CCEC N series engine products

Super power
The power covers 185-545 horsepower and the maximum torque is 1763 Newton meters.
The low-speed torque is large, the start is fast, and the climbing ability is strong.
The self-weight is 1250 kg, and the power-to-weight ratio is large.

Low fuel consumption and good economy
Cummins PT fuel system, ultra-high injection pressure, to ensure good engine atomization and full combustion.
The efficient Holset exhaust gas turbocharger can ensure full intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.
Air-to-air cooling technology ensures more sufficient air intake and better fuel economy.

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-valve design per cylinder, 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: Integral crankshaft 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.

Porduct application

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; it has formed strategic partnerships with important customers.
