Dalian diesel generator K50 series engine product performance characteristics
? Super power
Power covers 1250~2000 horsepower, the most The maximum torque is 7865 Newton meters .
The weight is 4946 kg, and the power to weight ratio is 0.404 horsepower / kg.
? Low fuel consumption and good economy
Cummins PT fuel system, ultra-high injection pressure, ensures good engine atomization and sufficient combustion.
The efficient Holset exhaust gas turbocharger can ensure more adequate air intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.
Air-to-intercooling technology ensures more adequate air intake and better fuel economy.
? Compact structure and easy maintenance
Replaceable wet cylinder liner has good heat dissipation effect and is easy to replace.
The parts of all models are highly versatile, highly serialized and easy to maintain.
Both the cylinder block and the cylinder head adopt built-in pressure lubricating oil passages, which have compact structure and low failure rate.
? Advanced design Reliable performance
Cylinder body: Made of high-strength alloy cast iron, with good rigidity, low vibration and low noise.
Cylinder head: Four-valve design per cylinder, optimized air / fuel mixing ratio, effectively improving combustion and emissions.
Camshaft: The single camshaft design can accurately control valve and injection timing, and the optimized cam profile can reduce impact force and improve reliability and durability.
Crankshaft: An integral crankshaft made of high-strength forged steel. The induction quenching process of fillets and journals can ensure higher fatigue strength of the crankshaft.
Piston: Using the latest aluminum alloy casting technology, the ω -shaped head and barrel-shaped skirt design can compensate for thermal expansion and contraction to ensure good fit.
? Professional configuration best quality
Lubrication system: All moving parts are forced lubrication; the large-capacity gear pump provides pressure lubricating oil to lubricate the bearings and cool the pistons; the oil cooler, full-flow filter, and bypass filter ensure that the oil is maintained in good condition.
Fuel system: Cummins PT fuel system optimizes combustion and provides surging power; STC step-by-step timing system ensures better combustion in all working conditions; it adopts a low-pressure fuel supply system and is equipped with a one-way fuel circuit, which is safe and reliable.
Cooling system: forced water cooling by gear centrifugal water pump, large flow water channel design, good cooling effect; spin-on water filter and special DCA additive can effectively control the acidity of the coolant, prevent rust and cavitation, and remove impurities.
Intake and exhaust system: The efficient Holset exhaust gas supercharger further improves combustion; the pressure-type pulse exhaust pipe can make full use of exhaust gas energy and improve engine efficiency; air-to-air intercooling technology ensures better fuel economy and emissions.
? Mature products, famous all over the world
Wide application: K50 series engines are widely used in engineering machinery, heavy-duty vehicles, power generation, ship power and other fields; it has formed strategic partners with important customers.
High reputation: As one of the main models of the Cummins family, the K50 series engines have won high recognition from customers in various fields for their strong power, ultra-low fuel consumption, high reliability and low maintenance costs.
Technology upgrade: Air-to-air intercooling, slow starting and other technologies have further improved the engine's reliability, power, fuel economy and emissions.
