Cummins QSK38 series engine product performance characteristics

QSK38 series engine product performance characteristics

• Super power　

          Power covers 1086~1650 horsepower and maximum torque is 6242 Newtons. meter

• Low fuel consumption and good economy

         Cummins PT fuel system, ultra high injection pressure, ensure good engine atomization, full combustion.

         The efficient Holset exhaust gas turbocharger ensures fuller intake, increasing engine efficiency, further improving combustion, and reducing engine specific fuel consumption.

         Air - to - air cooling technology guarantees fuller air intake and better fuel economy.

• Compact structure and easy maintenance

           Replaceable wet cylinder liner, good heat dissipation effect, easy to replace.

           All models have strong commonality, high degree of serialization and easy maintenance.

          Cylinder block and cylinder head are built - in pressure lubricating oil channel, compact structure, low failure rate.

　　• Advanced design and reliable performance

　      Cylinder block: made of high strength alloy cast iron, good rigidity, small vibration and low noise.

         Cylinder head: four valves per cylinder design, optimized air/fuel mix ratio, effectively improve combustion and emissions.

         Camshaft: Single camshaft design provides precise valve and injection timing control. Optimized CAM profiles reduce impact and improve reliability and durability.

         Crankshaft: It is a monolithic crankshaft made of high strength forged steel. The induction quenching process of fillet and journal ensures higher fatigue strength of crankshaft.

         Piston: Adopt the latest aluminum alloy casting technology, Ω-shaped head and barrel skirt design can compensate for thermal expansion and cold contraction, to ensure good cooperation.

• Professional configuration of the best quality

　　　Lubrication system: all moving parts are forced lubrication; Large capacity gear pump provides pressure lubricating oil to lubricate the bearing and cool the piston; Oil cooler, full flow filter, bypass filter to ensure good oil condition.

          Fuel system: Cummins PT fuel system, optimized combustion, power surging; STC step-by-step timing system ensures better combustion in all working conditions; Adopt low pressure oil supply system, configure fuel one-way circuit, safe and reliable.

         Cooling system: gear centrifugal water pump forced water cooling, large flow channel design, good cooling effect; Rotating water filters and special DCA additives can effectively control coolant acidity, prevent corrosion and cavitation and remove impurities.

         Intake/Exhaust System: Efficient Holset exhaust gas supercharger further improves combustion; The pressure pulse exhaust pipe can make full use of the exhaust energy and improve the engine efficiency. Air - to - air cooling technology guarantees better fuel economy and emissions.
