About Us

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 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.
