What’s the CCEC?

Chongqing Cummins Engine Co., Ltd. is a Sino-US joint venture. It was established in October 1995 and is located in the Martyrs’ Tomb in Shapingba District, Chongqing City. The Chinese parent company is Chongqing Electromechanical Co., Ltd., and the foreign parent company is Cummins (China) Investment Co., Ltd., and the investment ratio of both parties is 50%. There are more than 1400 employees. The predecessor of Chongqing Cummins was the Chongqing Automobile Engine Factory, which began the design and manufacture of diesel engines in the 1950s.

Chongqing Cummins Engine Factory
Chongqing Cummins is the starting point of Cummins’ localized production in China, and is Cummins’ largest heavy-duty and high-horsepower engine specialized manufacturing plant in China. In 1981, Cummins officially signed a license agreement with the former China National Heavy-Duty Truck Group, and began to produce Cummins high-horsepower diesel engines in Chongqing. After years of development, the cooperation between the two parties has continued to deepen. Chongqing Cummins has always been an important driving force for the rapid growth of Cummins’ business in China.

Leading products
The company mainly produces three series of Cummins N, K19, K38, K50, M11, diesel engines, generator sets and other power units. Products are suitable for heavy-duty vehicles, large passenger cars, construction machinery, mining machinery, petroleum machinery, rail machinery, port machinery, stationary and mobile diesel generator set power stations, marine propulsion power units and auxiliary power units, pump power units and other power units’ unit.

The main products meet the emission requirements of Stage 2 and Stage 3 (Euro 2 and Euro 3) for on-road diesel engines specified by Chinese national standards, American standards and European standards, as well as Stage 1 and Stage 2 emission requirements for off-highway diesel engines (Tier 1 and Tier 2). The engine power range produced by Chongqing Cummins is 200HP-1600HP. The products are mainly used in heavy-duty vehicles, large passenger cars, construction machinery, mining machinery, petroleum machinery, rail machinery, port machinery, stationary and mobile diesel generator sets, power stations, ship propulsion Power packs and auxiliary power packs, pump power packs and other power packs.

Major awards
N series engines were rated as China’s national high-quality products (silver award); N and K series engines and generator sets were rated as the first batch of famous brand products in Chongqing. The company has won the top 50 industrial enterprises in Chongqing for 15 consecutive years and the title of “Top Ten Foreign-Invested Enterprises in Chongqing” for 6 consecutive years.

More features of the CCEC engines.
Low fuel consumption and good economy

Cummins patented PT fuel system and ultra-high injection pressure ensure that the engine has good atomization and full combustion.
The high-efficiency Holset exhaust gas turbocharger can ensure more sufficient intake air, improve engine efficiency, further improve combustion, and reduce engine specific fuel consumption.
Air-to-air cooling technology ensures more adequate intake air and better fuel economy.

Compact structure and easy maintenance
