K19 series engine product performance characteristics
? Super power
The power covers 450-890 horsepower and the maximum torque is 2586 Newton meters.
It weighs 1838 kilograms and has a large power-to-weight ratio.
? Low fuel consumption and good economy
Dalian diesel generator 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 and 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 mixture ratio, effectively improves combustion and emissions; one head per cylinder, easy maintenance.
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 of the 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 maintain good oil condition.
Fuel system: Cummins PT fuel system optimizes combustion and provides surging power; the STC distributed timing system ensures better combustion under all working conditions; a low-pressure fuel supply system is configured 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 prevent rust and cavitation, control coolant acidity 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: Since Cummins entered China in 1975, the K19 series engines have been 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 K19 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. The QSK19 engine launched in 2008 uses electronic injection technology, with a power of 369-669kW, which can meet the third stage emission standards of non-road mobile machinery, further strengthening CCEC’s high-horsepower engine manufacturing in China.
