Cummins QSM11-C375 Industrial Diesel Engine

The Cummins QSM11-C375 is a high-performance industrial diesel engine developed for demanding non-road equipment. With increased rated power and strong mid-range torque, it supports heavy-duty applications that require consistent output and reliable load response.

Technical Specifications

• Rated power: 375 hp (280 kW) at 2100 rpm

• Maximum power: 400 hp (298 kW) at 1800 rpm

• Maximum torque: 1898 N·m at 1400 rpm

Because maximum torque is delivered at 1400 rpm, the engine provides powerful pulling force at commonly used working speeds. As a result, equipment maintains stable performance during lifting, climbing, and continuous-duty operations.

Strong Torque and Power Output

With torque reaching 1898 N·m, the QSM11-C375 ensures excellent load-bearing capability in demanding conditions. This strong mid-range torque improves acceleration under load and enhances overall machine responsiveness.

Moreover, maximum power of 400 hp at 1800 rpm allows the engine to deliver peak performance within a practical operating range. Therefore, it achieves an effective balance between high output and operational stability.

Stable Operation for Heavy-Duty Applications

The 375 hp rated power at 2100 rpm supports equipment that requires sustained performance across varying load conditions. In addition, the consistent torque curve helps reduce speed fluctuations during operation, which contributes to smoother power delivery.

Since the engine combines strong torque at 1400 rpm with high maximum power at 1800 rpm, it offers dependable performance in construction and other non-road environments where reliability is essential.

Conclusion

With 375 hp rated power and 1898 N·m maximum torque at 1400 rpm, the Cummins QSM11-C375 industrial diesel engine delivers powerful, stable, and reliable performance. It provides the strength and consistency required for demanding heavy-duty equipment applications.
