Performance characteristics of N series engine:

 

Super power:

 

Power coverage 185-545 horsepower, maximum torque of 1763 nm.

Low speed torque, fast start, strong climbing ability.

The engine weight is 1250KG, big power to weight ratio.

 

Low fuel consumption and good economy:

 

Cummins patented technology of PT fuel system, high injection pressure, to ensure good atomization of the engine and full combustion.

Efficient Holset exhaust turbocharger can ensure the intake be more fully, improve the efficiency of the engine, further improve combustion and reduce engine fuel consumption.

Air to air cooling technology to ensure that the intake is more adequate, and fuel economy is better.

 

Compact structure and convenient maintenance:

 

Wet cylinder liner can be replaced, heat dissipation effect is better, easier to replace.

All types of parts commonality, high degree of serialization, convenient maintenance.

The cylinder block and cylinder head adopts built-in pressure lubricating oil, compact structure, low failure rate.

Compound oil filter, convenient maintenance, reduce the cost of daily maintenance.

Overhaul mileage over 1 million km.

 

Advanced design, Reliable Performance:

 

Block: manufacturing high strength alloy cast iron, good rigidity, small vibration, low noise.

 

Cylinder head: four valves per cylinder design and optimization of air / fuel mixture ratio, effectively improve the combustion and emission; two cylinder cover and convenient maintenance.

 

Camshaft: large diameter cam shaft can bear a higher load, the new design can accurately control the valve and injection timing, optimization of the cam profile can reduce the impact force, improve reliability and durability.

 

Crankshaft: high strength forged steel crankshaft, fillet and shaft neck of the induction hardening process can ensure higher fatigue strength of the crankshaft.

 

Piston: the aluminum alloy casting technology, the Omega shaped head and barrel type skirt design can compensate the heat expansion and cold contraction to ensure good cooperation.

 

Professional configuration, the best quality:

 

Lubrication system: all the moving parts are forced lubrication; large capacity gear pump to provide pressure lubricating oil for lubrication and cooling the piston; oil cooler, composite filter to maintain good oil status.

 

Fuel system: PT fuel system of Cummins patent technology, combustion optimization, the surging momentum; STC distribution timing system to ensure full combustion better; using the low-pressure fuel supply system, fuel configuration unidirectional circuit, safe and reliable.

 

Cooling system: the centrifugal pump forced water-cooling and large flow channel design, the cooling effect is good; screwed type water filter and special DCA additive can effectively prevent corrosion and cavitation, control cooling liquid acidity and removing impurities.

 

Intake and exhaust system: high efficient Holset turbocharger further improve combustion; exhaust pressure type pulse tube can make full use of exhaust gas energy, improve the efficiency of the engine; air cooled technology to ensure fuel economy and better discharge.
