Product Introduction
In modern diesel HEUI (Hydraulically Actuated Electronically Controlled Unit Injector) systems, fuel injection is not driven directly by mechanical camshafts, but by high-pressure engine oil as a hydraulic medium. The 10R-2982 Actuation Pump plays a decisive role in this architecture-transforming rotational mechanical energy into stable, high-pressure oil flow required for injector actuation.
Unlike traditional diesel injection pumps, this unit focuses exclusively on oil pressurization, decoupling fuel delivery from injection timing, which significantly improves combustion control and emissions performance.
Structural Configuration & Design Logic
The 10R-2982 features a small flange housing combined with a 36-tooth gear interface, ensuring compatibility with compact engine layouts and precise synchronization with timing gear trains.
Key structural highlights:
✔️ Small flange mounting → optimized for tight engine compartments
✔️ 36-tooth drive gear → ensures stable torque transmission
✔️ No transfer pump → dedicated high-pressure oil circuit design
✔️ Integrated pressure regulation pathways
This configuration reduces parasitic load while maintaining consistent hydraulic output, especially under variable engine speeds.
