Introduction of Cummins CCEC KTA38 diesel engine

Cummins K38 series engine product performance characteristics

• Super power
Power covers 750-1600 HP with a maximum torque of 5469 Newton-meters.
Weight is 4222 kg, power weight ratio is large.

• Low fuel consumption and good economy
Cummins PT fuel system, ultra-high injection pressure, to ensure good engine atomization, full combustion.
The efficient Holset exhaust gas turbocharger ensures a fuller intake, increasing engine efficiency, further improving combustion and reducing engine specific fuel consumption.
Air – to – air intercooling technology to ensure full air intake, better fuel economy.

• Compact structure and easy maintenance
Replaceable wet cylinder liner, good heat dissipation effect, easy to replace.
All models of parts and components of strong versatility, high degree of serialization, easy maintenance.
Cylinder body and cylinder head adopt built-in pressure lubricating oil channel, compact structure, low failure rate.

• Advanced design and reliable performance
Cylinder block: high strength alloy cast iron manufacturing, good rigidity, small vibration, low noise.
Cylinder head: each cylinder four valve design, optimization of air/fuel mixture ratio, effectively improve combustion and emissions; One cover per cylinder, convenient maintenance.
Camshaft: Dual camshaft design provides precise control of valve and injection timing. Optimized CAM profile reduces impact force and improves reliability and durability.
Crankshaft: integral crankshaft made of high strength forged steel. Induction hardening process of fillet and journal ensures higher fatigue strength of crankshaft.
Piston: using the latest aluminum alloy casting technology, ω head and barrel skirt design can compensate for thermal expansion and contraction, to ensure a good match.

• Professional configuration with excellent quality

Lubrication system: all moving parts are forced lubrication; Large capacity gear pumps provide pressure lubricating oil to lubricate bearings and cool pistons; Oil cooler, full flow filter, bypass filter to maintain good oil condition.
Fuel system: Cummins PT fuel system, optimized combustion, power surge; STC distributed timing system ensures better combustion in all working conditions; Low pressure oil supply system, one-way fuel circuit, safe and reliable.
Cooling system: gear centrifugal water pump forced water cooling, large flow channel design, good cooling effect; Rotary water filter and special DCA additive can effectively prevent corrosion and cavitation, control coolant acidity and remove impurities.
Intake and exhaust system: Efficient Holset exhaust supercharger to further improve combustion; Pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; Air to air intercooling technology ensures better fuel economy and emissions.

• Mature products, worldwide reputation
Wide application: since Cummins entered China in 1975, K38 series engines have been widely used in construction machinery, heavy duty vehicles, power generation, Marine power and other fields. Establish strategic partnership with key customers.
High reputation: as one of the main models of cummins family, K38 series engines are highly recognized by customers in various fields for their powerful power, ultra-low fuel consumption, high reliability and low maintenance costs.
Technology upgrade: air-to-air intercooling, slow start and other technologies further improve engine reliability, power performance, fuel economy and emissions indicators. Introduced in 2008, the QSK38 engine uses electronic injection technology to achieve 806-1200kW, which can meet the third stage emission standards of non-road mobile machinery, further enhancing CCEC’s leading position in China’s high-horsepower engine manufacturing industry.
