Variable Displacement Oil Pump
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The variable displacement oil pump is designed to minimize energy loss. The active control matches the oil flow and pressure to the engine's need, eliminating excess oil flow, and reducing the load on the engine crankshaft to improve fuel economy.
The variable displacement oil pump works in two modes:
| Item | Description |
|---|---|
| 1 | Primary Port (always pressurized) |
| 2 | Pivot pin (slide pivots around pin in order to adjust the displacement of the rotating group) |
| 3 | Slide |
| 4 | Secondary Port (pressurized in low pressure mode, vented in high pressure mode) |
| Item | Description |
|---|---|
| 1 | Slide position at 100% displacement |
| 2 | Slide position at 0% displacement |
