Cummins QSM11-C300 Industrial Diesel Engine

The Cummins QSM11-C300 is a high-performance industrial diesel engine developed for demanding non-road applications. With two rated speed configurations, it offers flexible power matching while maintaining strong torque output at mid-range engine speed. As a result, it supports stable operation under varying load conditions.

Technical Specifications

The QSM11-C300 is available in two performance calibrations:

Configuration A

• Rated power: 300 hp (224 kW) at 2000 rpm

• Maximum power: 343 hp (256 kW) at 1800 rpm

• Maximum torque: 1575 N·m at 1400 rpm

Configuration B

• Rated power: 300 hp (224 kW) at 2100 rpm

• Maximum power: 300 hp (224 kW) at 1800 rpm

• Maximum torque: 1424 N·m at 1400 rpm

Because both versions deliver maximum torque at 1400 rpm, the engine provides strong pulling force and steady load response in practical operation. Therefore, it performs efficiently in equipment that requires reliable mid-speed output.

Strong Low-Speed Torque Performance

The torque output of up to 1575 N·m ensures solid performance during heavy-duty tasks. Even under continuous load, the engine maintains stable power delivery. Consequently, operators benefit from smoother acceleration, improved machine responsiveness, and consistent working efficiency.

Moreover, achieving maximum power at 1800 rpm allows the engine to balance performance and durability. This characteristic supports long operating hours while maintaining dependable output.

Flexible Power Matching

With two rated speed options, the QSM11-C300 allows equipment manufacturers to select the most suitable calibration according to application requirements. Whether prioritizing higher peak power or optimized rated speed performance, the engine provides adaptable configuration while maintaining the same 300 hp rated output.

Conclusion

The Cummins QSM11-C300 industrial diesel engine combines 300 hp rated power with strong torque at 1400 rpm. With flexible rated speed options and stable maximum power performance, it delivers reliable and efficient operation for demanding non-road equipment.
