Cummins NT855 series engine product performance characteristics? Super power power covers 185-545 hp and maximum torque of 1763 Newton meters. Low-speed torque, started fast, climbing ability. Weight 1250 kg, the power weight ratio. ? Low fuel economy is good Cummins PT fuel system patented technology, high injection pressure, ensure that the engine good atomization, combustion. Efficient Holset turbocharger exhaust intake ensures more fully, improve engine efficiency and further improve combustion and reduce engine specific fuel consumption. Air Cooling technology to ensure intake fuller, better fuel economy. ? Compact, easy maintenance replaceable wet cylinder liners, cooling effect, easy to replace. All models parts versatility, high degree of serialization, and easy maintenance. Block and head are taking a built-in pressure lubricants Road, compact, low failure rate. Composite oil filter, easy maintenance, lower routine maintenance costs. Overhaul mileage of more than one million kilometers. Shantui bulldozer Cummins NT855-C280 reliable cylinder design advanced features:? High-strength alloy cast iron, rigidity, vibration, low noise. Head: four-valve per cylinder design, optimized air / fuel ratio, improve combustion and emissions; a two-cylinder cover for easy maintenance. Camshaft: Large diameter camshaft can withstand higher loads, the new design can be precisely controlled valve and injection timing, cam profile optimization can reduce the impact force, improve reliability and durability. Crankshaft: high strength forged steel crankshaft overall, induction hardening process and journal fillets can guarantee higher fatigue strength of the crankshaft. Pistons: aluminum alloy using the latest technology, ω-type head and barrel skirt designed to compensate for thermal expansion and contraction, to ensure a good fit. ? Professional configuration best quality lubrication system: All the moving parts are forced lubrication; high-capacity gear pump provides pressure lubricating bearings are lubricated and cooled piston; oil cooler, oil composite filter to maintain good condition. Fuel system: Cummins PT fuel system patented technology to optimize combustion, power surge; STC distributed timing system to better ensure all conditions of combustion; low-pressure fuel system, fuel-way loop configuration, safe and reliable. Cooling system: Forced water-cooled centrifugal pumps, a big flow waterway design, cooling effect; spin-mounted water filters and special additives DCA can effectively prevent corrosion and cavitation, control coolant acidity and remove impurities. Intake and exhaust systems: efficient Holset turbocharger to further improve the combustion exhaust gas; pressure pulse exhaust pipe can take full advantage of exhaust energy, improve engine efficiency; Air Cooling technology ensures better fuel economy and emissions. ? Mature product, widely known around the world: Cummins since 1975 has begun to enter China, N series engines are widely used in construction machinery, heavy vehicles, power generation, marine power and other fields; with key customers formed a strategic partnership. High reputation: As one of the main models of Cummins family, N series engine with strong power, low fuel consumption, high reliability and low maintenance costs in various fields has won high recognition. Technology upgrades: Big BCIII camshaft design, empty cold, slow start technology to further improve the reliability, power, fuel economy and emissions and other indicators of the engine. Cummins is being jointly developed with EFI technology, will further enhance the N series engine in China leading horsepower engine manufacturing industry.
