The oil pump is a vital component in an engine's lubrication system, designed to circulate oil and ensure all moving parts are properly lubricated.
Typically, the oil pump is a mechanical pump that is driven by the engine's crankshaft. Its design and placement are strategic to effectively draw oil from the engine's reservoir.
Understanding the Oil Pump's Configuration
Based on common engine designs, the oil pump has specific characteristics regarding its type, drive, location, and how it accesses the oil:
- Pump Type: It is generally a mechanical pump, meaning it uses the rotational energy of the engine to generate oil flow and pressure.
- Power Source: The pump receives its power directly from the crankshaft. This direct drive ensures that as the engine speed increases, the oil pump's output also increases proportionally, providing adequate lubrication under varying engine loads and speeds.
- Location: The oil pump is typically situated low on the engine. A common position is at the front of the crankshaft, where it can be easily driven and positioned close to the oil sump.
- Oil Intake System: To draw oil from the sump (the bottom pan holding the engine oil), the pump is fitted with a short pick-up pipe. This pipe extends down into the oil in the sump. Attached to the end of the pick-up pipe is a mesh strainer. This strainer acts as a primary filter, preventing larger particles or debris that may be present in the sump from being drawn into the pump and circulated throughout the engine.
How the Oil Pump Works
The mechanical action of the pump, powered by the crankshaft, creates suction. This suction pulls oil from the base of the sump, through the protective mesh strainer, up the short pick-up pipe, and into the pump itself. The pump then pressurizes the oil before distributing it through passages (oil galleries) to lubricate the engine's bearings, pistons, and other critical components.
Key Features Summary
| Feature | Description |
|---|---|
| Type | Mechanical |
| Drive | Crankshaft-driven |
| Common Location | Low on engine, at front of crankshaft |
| Oil Source | Sump |
