QSB5.9-C210
Cummins

The Cummins QSB5.9-C210-30 is a premium 5.9-liter, 6-cylinder in-line industrial diesel engine designed for exceptional performance in demanding applications. With its advanced High-Pressure Common Rail (HPCR) fuel system and robust construction, this engine delivers 210 horsepower (154 kW) of reliable prime power, making it the ideal power source for heavy-duty industrial and construction equipment.
This industrial engine is engineered for a broad range of heavy-duty equipment, providing dependable power where it matters most. Its key applications include:
Construction Machinery: Excavators, wheel loaders, bulldozers, road rollers, and cranes.
Industrial Power Units: Generator sets, pump drives, and custom industrial power packs.
Specialized Vehicles: Suitable for certain heavy-duty trucks and bus applications.
The QSB5.9-C210-30 is built with Cummins' signature durability and incorporates several key technological advantages:
Advanced HPCR Fuel System: The Bosch electronically-controlled High-Pressure Common Rail system ensures precise fuel delivery, optimizing combustion for superior power response, fuel efficiency, and lower emissions regardless of engine speed.
Integrated Robust Design: The cylinder block and head employ an integrated design, significantly reducing potential leakage points and the overall number of parts by approximately 40%, which enhances structural integrity and reliability.
Heavy-Duty Components for Long Life: Critical components like the camshaft and crankshaft are made from forged steel. Combined with a high-strength cylinder block and platform mesh honing on cylinder bores, these features ensure high rigidity, excellent oil retention, and an extended service life under heavy loads.
Intelligent Electronic Controls: The engine's full-authority ECM allows for customizable features, including advanced diagnostics, performance monitoring, and system protection, ensuring optimal operation and ease of maintenance.
