A 3406 Cat engine, specifically the 3406C Industrial Diesel Engine, has a maximum torque of 1602 lb-ft (2172 Nm) at 1350 rpm.
Caterpillar's 3406 series engines are renowned for their robust performance and reliability, especially in heavy-duty industrial applications. The torque output is a critical factor indicating an engine's ability to perform work, particularly in applications requiring significant pulling or pushing power at lower RPMs, such as in construction equipment, agricultural machinery, or power generation.
3406C Industrial Diesel Engine Specifications
The performance characteristics of the 3406C Industrial Diesel Engine demonstrate its capabilities across various operational demands. Key specifications include:
| Metric | Value (Imperial) | Value (Metric) |
|---|---|---|
| Maximum Power | 465 hp | 347 kW |
| Minimum Power | 375 hp | 280 kW |
| Maximum Torque | 1602 lb-ft @ 1350 rpm | 2172 Nm @ 1350 rpm |
| Rated Speed | 1800-2100 rpm | 1800-2100 rpm |
These specifications highlight the engine's power delivery range and the point at which it achieves its peak twisting force.
Understanding Engine Torque
Torque is the rotational force an engine produces, which is crucial for accelerating loads and maintaining power through challenging conditions. For industrial applications, high torque at relatively low RPMs, like the 1350 rpm for the 3406C, signifies excellent lugging ability, allowing the engine to pull through tough spots without excessive downshifting or loss of momentum. This characteristic is particularly beneficial for:
- Heavy Equipment: Enabling excavators, bulldozers, and loaders to move large quantities of material efficiently.
- Industrial Pumps: Providing consistent power for fluid transfer in demanding environments.
- Power Generation: Ensuring stable and reliable operation for generators.
The balance between power (horsepower/kilowatts) and torque is essential for an engine's overall performance profile. While horsepower relates to how fast work can be done, torque relates to the initial grunt or pulling power available. The 3406C's specifications reflect an engine designed for durability and high output in rigorous industrial settings.
