- Oils are capable of capturing and transporting any pollutants present in the engine.
- Larger particles are filtered out of the motor oil by the oil filter, while tiny, soft particles remain suspended in the engine oil until the oil has to be replaced.
- The addition of detergent chemicals to the oil during the refining process ensures that particles remain suspended and are not deposited on surfaces.
- In your engine, as motor oil is forced through the engine at high pressure, it leaves behind a thin lubricating residue or film that adheres to internal components such as the cylinder walls and piston rings, as well as the valves, camshaft, and all of the other moving components.
- This film offers a smooth surface on which to work.
- It also separates the metal pieces from the rest of the machine.
What does oil do in an engine?
While the oil’s primary function is to keep engine parts moving, it accomplishes this aim by performing a variety of other jobs while it is present in the engine system. The oil initially covers the moving parts within the engine itself, allowing them to glide rather than crash with one another, which would result in loud sounds and premature wear of the parts due to high friction.
How does an engine lubrication system work?
The lubrication system of an engine is comprised of a sump (where the majority of the oil is kept), oil galleries (which function similarly to veins in the body that transfer blood), an oil pump (which is effectively the brain of the operation), and finally, a filter (like kidneys, this removes any impurities from the oil before it is pumped through the motor).
How does an oil cooling system work?
When the oil returns to the engine sump, it is cooled by the external air that flows over the surface of the sump before being re-circulated through the system to perform its other functions. This all occurs at the same time that the engine vibrates, and the cushion of oil lubrication helps to minimize the impact of the vibration.
How does oil film lubrication work?
- With each stroke of the engine, when oil is forced through the engine under pressure, it leaves behind a particular lubricating film (oil film) that generates a slippery surface (or slip effect) over anything it comes into contact with.
- The fundamental function of oil film lubrication is to guarantee that the engine’s components operate smoothly while simultaneously reducing friction and component wear.
