CHONGQING CUMMINS Engine【K38】

K38 series engine products performance characteristics

• super power

The power covers 750-1600 horsepower with a maximum torque of 5,469 Newton meters.
The dead weight is 4222 kg, and the power dead weight ratio is large.
• low fuel consumption and good economy
Cummins patented PT fuel system with super high injection pressure ensures good engine atomization and sufficient combustion.
The efficient Holset exhaust gas turbocharger can ensure more adequate intake, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.
Air – to – air cooling technology ensures more adequate intake and better fuel economy.
• compact structure and easy maintenance
Replaceable wet cylinder liner, good heat dissipation effect, easy to replace.
The parts and components of all models have strong universality, high degree of serialization and convenient maintenance.
The cylinder body and the cylinder head adopt the built-in pressure lubricating oil passage, the structure is compact, the failure rate is low.
• advanced design and reliable performance
Cylinder block: high strength alloy cast iron, good rigidity, small vibration, low noise.
Cylinder head: four valves for each cylinder are designed to optimize the air/fuel mixture ratio and effectively improve combustion and emissions; One cover per cylinder for easy maintenance.
Camshaft: dual camshaft design allows accurate control of valve and injection timing, optimized CAM profile reduces impact, improves reliability and durability.
Crankshaft: integral crankshaft made of high strength forged steel, the induction quenching process of rounded corner and shaft neck can ensure higher fatigue strength of crankshaft.
Piston: using the latest aluminum alloy casting technology, the head and barrel skirt design can compensate for thermal expansion and contraction, ensuring a good fit.
• professional configuration of the best quality
Lubrication system: all moving parts are forced lubrication; Large capacity gear pump to provide pressure lubricating oil for bearing lubrication and cooling piston; Oil cooler, full flow filter, bypass filter to maintain good oil condition.
Fuel system: cummins patented PT fuel system, optimized combustion, power surges; STC timing distribution system ensures better combustion under all working conditions; Adopt low pressure oil supply system, equipped with one-way fuel loop, safe and reliable.
Cooling system: the gear centrifugal pump forced water cooling, large flow channel design, good cooling effect; Spiral-mounted water filter and special DCA additive can effectively prevent corrosion and cavitation corrosion, control the acidity of coolant and remove impurities.
Intake and exhaust system: efficient Holset exhaust gas supercharger to further improve combustion; The pressure pulse exhaust pipe can make full use of the exhaust energy and improve the engine efficiency. Air – to – air cooling technology ensures better fuel economy and emissions.
• mature products, renowned around the world
Extensive applications: since cummins entered China in 1975, K38 series engines have been widely used in engineering machinery, heavy 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 have won high recognition from customers in various fields with strong power, ultra-low fuel consumption, high reliability and low maintenance cost.
Technology upgrade: air to air cooling, slow start and other technologies further improve the engine reliability, power performance, fuel economy and emissions and other indicators. The QSK38 engine, launched in 2008, adopts the electronic injection technology, and its power reaches 806-1200kw, which can meet the third stage emission standard of non-road mobile machinery, and further strengthen the leading position of CCEC in China’s high-horsepower engine manufacturing industry.
