The atures of the CCEC engine.
Low fuel consumption, good economy
Cummins patented PT fuel system and ultra-high injection pressure ensure good engine atomization and full combustion.
The efficient Holset exhaust turbocharger ensures more air intake, improves engine efficiency, further improves combustion, and reduces engine specific fuel consumption.
Air-to-air cooling ensures more adequate intake and better fuel economy.
Compact structure, easy maintenance
Wet cylinder liner can be replaced, heat dissipation effect is good, easy to replace.
All models of parts and components have strong universality, high degree of serialization and easy maintenance.
Cylinder body and cylinder head are built in pressure lubricating oil channel, compact structure, low failure rate, advanced design, reliable performance
Cylinder block: Made of high strength alloy cast iron, good rigidity, low vibration, low noise.
Cylinder head: four valves per cylinder design, optimize the air-fuel ratio, effectively improve combustion and emissions; One head per cylinder, easy to maintain.
Camshaft: The single camshaft design provides precise control over valve and injection timing, and optimized CAM profiles reduce impact force and improve reliability and durability.
Crankshaft: AN INTEGRATED CRANKSHAFT MADE OF high STRENGTH forged STEEL, THE INDUCTION quenching process of FILlet and journal can ensure higher fatigue strength of the crankshaft.
Piston: Adopt the latest aluminum alloy casting technology, ω-shaped head and barrel skirt design, can compensate thermal expansion and cold contraction, ensure good fit.

Professional configuration quality first
Lubrication system: force lubrication of all moving parts; Large capacity gear pump to provide pressure lubricating oil lubrication bearing and cooling piston; Oil cooler, full flow filter, bypass filter to maintain good oil condition.
Fuel system: Cummins patented PT fuel system, optimized combustion, surging power; STC distributed timing system ensures better combustion under all working conditions; Low pressure oil supply system, equipped with one-way oil circuit, safe and reliable.
Cooling system: gear centrifugal water pump forced water cooling, large flow channel design, cooling effect is good; Rotary water filters and special DCA additives prevent rust and cavitation, control coolant acidity and remove impurities.
Intake and exhaust system: efficient Holset exhaust gas supercharger further improves combustion; Pressure pulse exhaust pipe can make full use of exhaust energy and improve engine efficiency; Air-to-air cooling ensures better fuel economy and emissions.

Mature products, worldwide reputation
Wide range of applications: Since 1975 Cummins entered China, Cummins series engine has been widely used in construction machinery, heavy vehicles, power generation, Marine power and other fields; Develop strategic partnerships with key customers.

High reputation: As one of the main models of Cummins family, Cummins series engine has won high recognition from customers in all fields with its strong power, ultra-low fuel consumption, high reliability and low maintenance cost.
