Cummins QSM11-C350 Industrial Diesel Engine
The Cummins QSM11-C350 is a high-output industrial diesel engine engineered for demanding non-road applications. With two rated speed configurations and strong mid-range torque, it delivers flexible power matching and stable performance under heavy load conditions.
Technical Specifications
The QSM11-C350 is available in two performance calibrations:
Configuration A
-
Rated power: 350 hp (261 kW) at 2100 rpm
-
Maximum power: 385 hp (287 kW) at 1800 rpm
-
Maximum torque: 1776 N·m at 1400 rpm
Configuration B
-
Rated power: 350 hp (261 kW) at 2000 rpm
-
Maximum power: 372 hp (277 kW) at 1800 rpm
-
Maximum torque: 1830 N·m at 1400 rpm
Because both versions deliver peak torque at 1400 rpm, the engine ensures strong pulling force and stable load response during typical working speeds. As a result, equipment maintains consistent output even in demanding operating environments.
Powerful Mid-Range Torque Performance
With torque reaching up to 1830 N·m, the QSM11-C350 supports heavy-duty applications that require sustained force and high productivity. The strong torque curve improves acceleration under load and enhances operational stability during climbing, lifting, or continuous duty cycles.
Moreover, maximum power is achieved at 1800 rpm in both configurations. Therefore, the engine balances peak output with efficient operating speed, supporting long service life and dependable performance.
Flexible Power Matching
The two rated speed options allow equipment manufacturers to select the most suitable calibration based on machine design and duty cycle requirements. Whether prioritizing higher peak power or higher torque output, the QSM11-C350 provides adaptable performance while maintaining the same 350 hp rated power.
Conclusion
With 350 hp rated power and up to 1830 N·m maximum torque at 1400 rpm, the Cummins QSM11-C350 industrial diesel engine delivers strong, stable, and reliable performance. Its flexible configurations and high torque capability make it a dependable solution for demanding non-road equipment applications.
