Chongqing Cummins Engine Co., Ltd. is a Sino-U.S. joint venture established in 1995, with a 50/50 investment ratio between Cummins (China) Investment Co. QSK19, K38/QSK38 and K50/QSK50 series of diesel and natural gas engines in the power range of 185 - 3650 hp.
Application Areas: Suitable for heavy-duty vehicles, construction machinery, mining machinery, petroleum machinery, rail machinery, harbor machinery, stationary and mobile diesel generator sets, ship propulsion power units and auxiliary power units, pump power units and other power units. For example, in the field of power generation, a series of models have been developed for power generation applications, with power ranging from 200 - 1783kW; in the marine field, they are suitable for all kinds of ship propulsion and power generation applications in rivers, lakes and oceans, with displacement from 13 liters to 50 liters, and power ranging from 179kW to 1641kW.
Technical features:
Strong power: For example, the QSN model adopts the Cummins CELECT electronic control system with high power and strong power for heavy load. High torque and strong power.
Good fuel economy: some models use advanced combustion technology and optimized fuel system to fully combust fuel and reduce fuel consumption.
Emission standards: EFI models QSNT, QSK19, QSK38, QSK50 meet the requirements of China's non-road Stage III emission regulations, and some models also meet the requirements of Europe and North America's Stage III emissions (Tier 3).
Excellent low-temperature starting performance: The 19L methanol version launched in 2024 has an innovative cold-start technological solution that allows it to start normally at minus 30 degrees Celsius.
R&D capability: no less than 5% of the annual revenue from main business is spent on R&D. It has a Cummins high-horsepower engine R&D center, whose test benches are all equipped with electric dynamometer systems, with a power of up to 3,000kW, and are capable of undertaking performance, emission, and reliability testing of engines with a displacement ranging from 14L to 72L. By the end of 2023, the number of innovation projects reached 25, among which 13 innovation projects have been incubated, and a total of 16 national standards, industry standards and group standards have been revised by the company in the past three years.
Honors: For more than 20 consecutive years, the company has been rated as one of the top 50 industrial enterprises in Chongqing, one of the top 10 foreign-invested enterprises in Chongqing for 13 consecutive years, and one of the quality and efficiency enterprises in Chongqing for 15 consecutive years.
