N Series Cummins Engine

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

• The PT fuel system with low fuel consumption and good economy
with Cummins patented technology has ultra-high injection pressure to ensure good engine atomization and sufficient combustion.
The efficient Holset exhaust gas turbocharger can ensure more intake, improve engine efficiency, further improve combustion, and reduce engine fuel consumption.
Air-air intercooling technology ensures more sufficient air intake and better fuel economy.

• Compact structure and easy maintenance
to replace wet cylinder liner, good heat dissipation effect and easy replacement.
All models have strong versatility, high serialization, and easy to maintain.
Both the cylinder block and the cylinder head adopt a built-in pressure lubricating oil channel, which has a compact structure and a low failure rate.
Composite engine oil filter, easy maintenance, and reduce daily maintenance costs.
The overhaul mileage is more than 1 million kilometers.

• Designed with advanced performance reliable
cylinder block: made of high-strength alloy cast iron, good rigidity, low vibration and low noise.
Cylinder head: Four valves per cylinder, optimized air/fuel mixing ratio, combustion and emissions; two cylinders and one cover, for easy maintenance.
Camshaft: Large diameter camshafts can withstand higher loads, the new design controls valve and fuel injection timing, and the optimized cam-shaped line reduces impact, improves 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 fatigue strength of the crankshaft.
Piston: Use aluminum alloy casting technology, the ω-shaped head and barrel skirt design can compensate for thermal expansion and contraction, ensuring good cooperation.


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: PT fuel system with Cummins patented technology, optimized combustion and strong power; STC distributed timing system ensures good combustion in all working conditions; low-pressure oil supply system is adopted, equipped with a one-way fuel circuit, which is reliable.
Cooling system: Forced water cooling with centrifugal water pump, large flow water channel design, good cooling effect; rotary water filter and DCA additives can 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 to improve
