| Feature | Specification / Description |
|---|---|
| Engine Model | Cummins QSB3.3 |
| Configuration | In-line 4 cylinders, 4-Stroke |
| Displacement | 3.3 Liters |
| Aspiration | Turbocharged and Aftercooled |
| Fuel System | High-Pressure Common Rail (HPCR) |
| Control System | Full-Authority Electronic Control Module (ECM) |
| Typical Power Range | Up to 110 HP (82 kW) range |
| Emissions Compliance | Meets Tier 3 / Stage IIIA and equivalent global standards |
Note: For precise power, torque, and certified emission levels for specific markets, please consult official Cummins documentation.
The versatility and compact design of the QSB3.3 make it an excellent power source for various sectors:
Construction & Agriculture: Powers compact track loaders, skid-steer loaders, small excavators, trenchers, and agricultural machinery such as sprayers and balers.
Material Handling: An ideal engine for forklifts, aerial work platforms (AWPs), and other industrial handling equipment.
Power Generation: Serves as a reliable prime mover for small to mid-sized diesel generator sets, providing primary or standby power.
Industrial Pumps & Compressors: Used to drive light-duty industrial pumps, air compressors, and welding machines.
High-Pressure Common Rail (HPCR) Fuel System: The engine utilizes a state-of-the-art HPCR system for precise fuel injection control. This technology enables multiple injection events per cycle, resulting in superior combustion efficiency, significantly lower noise and vibration, improved fuel economy, and reduced emissions.
Advanced Electronic Control & Diagnostics: Managed by a full-authority Electronic Control Module (ECM), the engine features intelligent performance optimization, comprehensive system diagnostics, and built-in protection features. This "smart" system ensures optimal operation, simplifies troubleshooting, and allows for easy integration with modern machine control systems.
Compact & Durable Architecture: Engineered with a compact footprint and low weight, the QSB3.3 is easy to install in space-constrained equipment. Despite its size, it is built with robust components like a strong cylinder block and gear-driven camshaft, ensuring durability and reliability in tough working conditions.
Excellent Serviceability: The design prioritizes ease of maintenance with grouped service points and extended service intervals for oil and filters, helping to reduce downtime and lower operating costs over the engine's lifecycle.
