Performance characteristics of Cummins CCEC QSK38 series engine products
• Super power
The power ranges from 1,086 to 1,650 horsepower, and the maximum torque is 6,242 N.m. the
The self-weight is 3958 kg, and the power-to-weight ratio reaches 0.417 hp/kg

• Low fuel consumption and good economy
Cummins PT fuel system, ultra-high injection pressure, ensures good atomization and complete combustion of the engine. the
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.

• Compact structure, easy maintenance
The wet cylinder liner can be replaced, with good heat dissipation effect and easy replacement. the
The parts and components of all models have strong versatility, high degree of serialization, and easy maintenance. the
Both the cylinder block and the cylinder head adopt built-in pressure lubricating oil passages, which have a compact structure and low failure rate.

• Advanced design and reliable performance
Cylinder block: Made of high-strength alloy cast iron, with good rigidity, small vibration and low noise. the
Cylinder head: four-valve design per cylinder, optimized air/fuel mixture ratio, effectively improving combustion and emissions. the
Camshaft: The single camshaft design can precisely control the valve and fuel injection timing, and the optimized cam profile can reduce the impact force, improve reliability and durability. the
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. the
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 a good fit.

• Professional configuration, excellent quality
Lubrication system: All moving parts are forced to lubricate; 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 kept in good condition. the
Fuel system: Cummins PT fuel system, optimized combustion, surging power; STC step-by-step timing system ensures better combustion under all working conditions; low-pressure fuel supply system, equipped with fuel one-way circuit, safe and reliable. the
Cooling system: 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 control the acidity of the cooling liquid, prevent rust and cavitation and remove impurities. the
Intake and exhaust system: 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 and emissions.

• Mature products, well-known all over the world
Wide range of applications: QSK38 series engines are widely used in construction machinery, heavy-duty vehicles, power generation, ship power and other fields; and form strategic partnerships with important customers. the
High reputation: As one of the main models of the Cummins family, the QSK38 series engine has won high recognition from customers in various fields for its strong power, ultra-low fuel consumption, high reliability and low maintenance cost. the
Technology upgrade: air-to-air cooling, slow start and other technologies have further improved the engine’s reliability, power, fuel economy and emissions. The QSK38 engine adopts EFI technology, which can meet the third-stage emission standard of non-road mobile machinery, further enhancing the
