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.
