  • Design Reliable performance
Cylinder: Made of high-strength alloy cast iron, good rigidity, low vibration and low noise.
Cylinder head: Four valves per cylinder are designed, optimized air/fuel mixing ratio, and combustion and emissions are guaranteed; two cylinders and one cover, for easy maintenance.
Camshaft: Large diameter camshafts can withstand higher loads, the new design can ensure the control of valves and fuel injection timing, and the optimized cam-shaped line can reduce impact force, improve reliability and durability.
Crankshaft: The integrated crankshaft made of high-strength forged steel, the induction hardening process of rounded corners and journals can ensure higher crankshaft fatigue strength.
Piston: Use aluminum alloy casting technology, the ω-shaped head and barrel skirt design can compensate for thermal expansion and contraction, ensuring good cooperation.
  • Professional configuration quality
Lubrication system: All moving parts are forced lubricated; large-capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; engine oil cooler and composite filter maintain good engine oil condition.
Fuel system: Cummins technology PT fuel system, optimized combustion and strong power; STC distributed timing system has better combustion in all working conditions; low-pressure oil supply system is used, and fuel unidirectional circuit is equipped, .
Cooling system: Forced water cooling is adopted for centrifugal water pump, with a large flow water channel design, and good cooling effect; rotary water filter and special DCA additives can effectively prevent rust and cavitation, control the acidity of the coolant and remove impurities.
Intake and exhaust system: The efficient Holset exhaust gas supercharger further improves combustion; the pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; the air-to-air intercooling technology has better fuel economy and emissions.
  • Mature products,
  Wide application: Since Cummins entered China in 1975, N series engines have been widely used in engineering machinery, heavy vehicles, power generation, marine power and other fields; they have formed strategic partners with important customers.
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 for its strong power, maximum fuel consumption, high reliability and low maintenance costs.
Technology upgrade: The BCIII design, air-to-air cooling, slow start and other technologies of the large camshaft have further improved the engine's reliability, power, fuel economy and emission indicators. The electro-injection technology that is being developed in joint development with Cummins will further enhance the N-series engine's success in China's high-horsepower engine manufacturing industry.
