How an oil filter works? Detailed Guide for Beginners

In the modern world, we rely on a wide variety of machinery, including vehicles, airplanes, etc. , in order to carry out our everyday activities. In order to function, these objects need oil. When we use the same oil for a significant amount of time in a variety of machinery, autos, and airplanes, the oil will often get dirtier with time.

The engine’s performance will deteriorate over time as a direct result of the unclean oil. Because of this, we make use of oil filters. The use of an oil filter may assist in the removal of contaminated particles from the engine oil.

It’s possible that you’re wondering how an oil filter works. Because it is essential for us to know how this filter works, it will be the topic of discussion in the following paragraphs of this article.

What is an oil filter?

What is an oil filter

The removal of contaminants, dust and unburned fuel from circulation is the primary function of a mechanical device known as an oil filter. The component is responsible for preventing dirt from entering the engine while allowing only the transmission of fresh oil. Because of this, the oil filter has to be serviced or replaced after a certain amount of time has passed.

The major functions of an oil filter are:

  1. Since clean oil is necessary for constant engine performance, the oil filter purifies the engine oil.
  2. Oil, mud, and other substances are thickened by soot. In order to prevent thick oil from entering the engine, oil filters include several thinning holes.
  3. If the filter works properly, all moving components, including the camshaft, valvetrain, and connecting rods, are covered from wear and damage.

Working process of oil filter

Working process of oil filter

The oil filter helps to keep the engine and its performance top-notch. If there is no oil filter in a required machine, then the engine will easily get damaged and lose its performance efficiency.

There is a proper structure in the working process of an oil filter. And It is essential for us to know the process of the way an oil filter works. Now, we will be discussing the working process of an oil filter.

Working process

On the exterior of the filter is a metal container that has a sealing gasket that enables it to be kept snugly against the mating surface of the engine.

The gasket is held in place by the base plate of the can, which is also perforated with holes surrounding the region immediately within the gasket. A threaded center hole is designed to connect with the oil filter assembly that is located on the engine block.

The filter material may be found within the container, and it is almost always manufactured out of synthetic fiber. The oil pump in the engine sends the oil straight to the filter, and the oil enters the filter via the holes that are located around the base plate.

The contaminated oil is forced through the filter media and then back through the central hole, where it again enters the engine.

So, this is the working process of the oil filter that is shown above.

Oil Filter – How it works


What is the purpose of the oil filter?

The oil filter is used for removing pollutants from the engine oil of your automobile that may grow over time as the oil maintains the engine clean. Clean motor oil is crucial since, if the oil is unfiltered for a while, it could get saturated with microscopic, hard particles that really can wear down engine surfaces.

How often should an oil filter be replaced?

The oil filter should be changed every time a person changes the oil. Once each three to six months, most automobiles need to have their oil changed. Every time you have an oil change, replace the filter as some manufacturers advise since doing so keeps it from clogging too soon.

What kinds of oil filters are there?

There are three different kinds of oil filters:

  1. Centrifugal Type Oil Filter.
  2. Cartridge Type Oil Filter.
  3. Edge Type Oil Filter.

What happens when you’re using the inaccurate oil filter?

By using the inaccurate oil filter, issues with oil pressure or leaks may result from the filter’s inability to seal effectively. Even improper oil filters practically coming off have happened.

If your engine runs out of oil, an oil leak won’t only leave your driveway in a messy situation, but also catastrophic damage may result.

Do oil filters all the same?

Although you should double-check with the manufacturer of your car to be sure, most automotive filters designed for current cars may be used with any kind of oil. You don’t require a unique or modified oil filter while using synthetic oil, according to every leading motor oil manufacturer.

How can I tell whether the oil filter in my car is bad or not?

Low oil pressure is caused by a defective oil filter.  It causes frequent oil leaks in addition to causing the engine to overheat. The engine’s performance also significantly deteriorates.

Does an oil filter affect the performance of the engine?

A decrease in acceleration and a sluggish accelerator are the most typical symptoms of a malfunctioning oil filter. The engine won’t stop, but if you keep driving the car in that situation, the damage will spread to other engine components.

Final Words

How an oil filter works

The use of an oil filter is something that is included in a significant amount of day-to-day operations. It is extremely vital to have a basic understanding of what an oil filter is, how it functions, and the reasons why it is necessary to use one.

The working procedure of an oil filter has been broken down and explained in further detail in this article. Now that we are aware of all of these things, we are able to simply identify the working procedure of our oil filters as well as their current state of them.
