Chongqing Cummins Engine Co., Ltd. (CCEC) is a Sino‑US joint‑venture manufacturer of high‑horsepower diesel engines, established in 1995. As Cummins’ key production and R&D base for high‑power engines in China, CCEC manufactures products in compliance with Cummins global quality standards. Its engines are widely applied to diesel generator sets, mining equipment, petroleum machinery, marine equipment and construction machinery.

Product Series

CCEC mainly produces mechanical and electronic‑controlled diesel engine series including M11, NT855/QSN, K19/QSK19, K38/QSK38 and K50/QSK50.

Horsepower range: 185‑2500 HP. Matched power for generator sets: 200‑1800 kW, covering both standby and prime‑power station requirements.

Displacement: 10.8L‑50L. Product portfolio includes mechanical‑pump models and China‑Stage III electronic‑controlled versions. Multi‑fuel platforms such as natural gas and methanol are also available for low‑carbon projects.

Core Advantages

✅ Robust durability for heavy‑duty operation

Built with high‑strength alloy cylinder block, replaceable wet cylinder liners and forged steel crankshaft. Designed for continuous heavy‑load conditions, the engines perform reliably in high‑temperature, dusty and harsh field environments with long overhaul intervals for industrial non‑stop operation.

✅ Strong power output & fuel economy

Adopting PT fuel system or electronic fuel injection technology for high torque reserve and stable power delivery. Optimized combustion design delivers competitive fuel efficiency under normal load and reduces long‑term operating costs.

✅ Compliant emissions & diverse options

Electronic‑controlled models meet China Non‑Road Stage III emission standards, suitable for data centers, commercial buildings and municipal projects. Mature mechanical versions offer cost‑effective solutions for renovation projects and field sites with less stringent emission requirements.

✅ Ample spare parts & nationwide service network

Nationwide authorized Cummins service stations ensure easy access to common spare parts and lower maintenance costs compared with fully imported units. Global warranty support is available for overseas projects.

✅ Wide application compatibility

Ideal for diesel generator sets (standby power, prime‑power stations, mobile power stations), mining machinery, oil‑field equipment, construction machinery, marine main/auxiliary engines and pump drives.

Typical Application Scenarios

.Standby power for industrial plants, hospitals, data centers and commercial complexes

.Prime‑power supply for mines and oil‑field field operations

.Mobile power equipment for municipal and road‑bridge construction

.Marine propulsion & auxiliary power, pump drive units

.With decades‑long market validation, CCEC high‑power diesel engines are a well‑recognized prime‑mover option for large‑and‑medium power generation projects, balancing performance, reliability and convenient after‑sales support.
