Introduction of Cummins CCEC NTA855 diesel engine

Cummins N series engine product performance characteristics

• Super power
Power covers 185-545 horsepower with a maximum torque of 1763 Newton-meters.
Low speed torque, fast start, good climbing ability.
Weight 1250 kg, power weight ratio is large.

• Low fuel consumption and good economy
Cummins PT fuel system, ultra-high injection pressure, to ensure good engine atomization, full combustion.
The efficient Holset exhaust gas turbocharger ensures a fuller intake, increasing engine efficiency, further improving combustion and reducing engine specific fuel consumption.
Air – to – air intercooling technology to ensure full air intake, better fuel economy.

• Compact structure and easy maintenance
Replaceable wet cylinder liner, good heat dissipation effect, easy to replace.All mod
els of parts and components of strong versatility, high degree of serialization, easy maintenance.
Cylinder body and cylinder head adopt built-in pressure lubricating oil channel, compact structure, low failure rate.
Compound oil filter, easy maintenance, reduce daily maintenance costs.
The overhaul mileage exceeds 1 million kilometers.

• Advanced design and reliable performance
Cylinder block: high strength alloy cast iron manufacturing, good rigidity, small vibration, low noise.
Cylinder head: each cylinder four valve design, optimization of air/fuel mixture ratio, effectively improve combustion and emissions; Two cylinders and one cover, easy maintenance.
Camshaft: Large diameter camshaft for higher loads, new design for precise valve and injection timing control, optimized CAM profile to reduce impact, improve reliability and durability.
Crankshaft: integral crankshaft made of high strength forged steel. Induction hardening process of fillet and journal ensures higher fatigue strength of crankshaft.
Piston: using the latest aluminum alloy casting technology, ω head and barrel skirt design can compensate for thermal expansion and contraction, to ensure a good match.

• Professional configuration with excellent quality
Lubrication system: all moving parts are forced lubrication; Large capacity gear pumps provide pressure lubricating oil to lubricate bearings and cool pistons; Oil cooler, compound filter to maintain good oil condition.
Fuel system: Cummins PT fuel system, optimized combustion, power surge; STC distributed timing system ensures better combustion in all working conditions; Low pressure oil supply system, one-way fuel circuit, safe and reliable.
Cooling system: centrifugal pump forced water cooling, large flow channel design, cooling effect is good; Rotary water filter and special DCA additive can effectively prevent corrosion and cavitation, control coolant acidity and remove impurities.
Intake and exhaust system: Efficient Holset exhaust supercharger to further improve combustion; Pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; Air to air intercooling technology ensures better fuel economy and emissions.

• Mature products, worldwide reputation
Wide application: Since Cummins entered China in 1975, N series engines have been widely used in construction machinery, heavy duty vehicles, power generation, Marine power and other fields. Establish strategic partnership with key customers.
High reputation: As one of the main models of cummins family, N series engine has won high recognition from customers in various fields for its powerful power, ultra-low fuel consumption, high reliability and low maintenance cost.
Technology upgrade: BCIII design of large camshaft, air-to-air intercooling, slow start and other technologies further improve engine reliability, power performance, fuel economy and emissions indicators. The electro-injection technology being jointly developed with Cummins will further enhance the n-series engine’s leading position in China’s high-horsepower engine manufacturing industry.
