K19 is proof that dependable high-horsepower performance can be delivered in a compact package. The clean, efficient inline six-cylinder K19 engine design has been in Cummins product line for over 30 years delivering the lowest total cost of ownership while providing maximum productivity and durability. With ratings from 450 hp to 890 hp (336 – 650 kW), K19 engines have proven performance with the mechanical simplicity of Cummins PT® fuel system.
Cummins PT fuel system, ultra-high injection pressure, ensures good atomization and complete combustion of the engine.The high-efficiency Holset exhaust gas turbocharger can ensure more sufficient air intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.The air-to-air cooling technology ensures more sufficient air intake and better fuel economy.
The wet cylinder liner can be replaced, with good heat dissipation effect and easy replacement. The spare parts of all models are highly versatile, highly serialized, and easy to maintain. Both the cylinder body and the cylinder head adopt built-in pressure lubricating oil passages, with compact structure and low failure rate.
Cylinder block: Made of high-strength alloy cast iron, with good rigidity, small vibration and low noise. Cylinder head: Four-valve design per cylinder, optimized air/fuel mixture ratio, effectively improving combustion and emission; one head per cylinder, easy maintenance. Camshaft: The single camshaft design can precisely control the valve and fuel injection timing, and the optimized cam profile can reduce the impact force and improve reliability and durability. Crankshaft: Integral crankshaft made of high-strength forged steel. The induction hardening process of rounded corners and journals can ensure higher fatigue strength of the crankshaft.
All moving parts are forced to lubricate; the large-capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; the oil cooler, full-flow filter, and bypass filter maintain good oil condition.
Cummins PT fuel system, optimized combustion, surging power; STC distributed timing system ensures better combustion under all working conditions; low-pressure fuel supply system, equipped with fuel one-way circuit, safe and reliable.
forced water cooling by gear centrifugal water pump, large flow channel design, good cooling effect; spin-on water filter and special DCA additive can effectively prevent rust and cavitation, control the acidity of the cooling liquid and remove impurities.
High-efficiency Holset exhaust gas supercharger further improves combustion; pressure-type pulse exhaust pipe can make full use of exhaust gas energy and improve engine efficiency; air-to-air cooling technology ensures better fuel economy.
