Air oil separator is an important part of a vehicle which is often not known by many drivers. The main function of it is to separate the oil particles in the ventilation system of an engine so that it allows clean combustion, thereby improving the power of the engine, reducing oil consumption and prolonging the life cycle of an engine.This article discusses the air oil separator in detail. It covers its importance, its functions, the common problems about it, how to handle it, the effects of it on the performance of a vehicle. If you are interested in it, please pay attention to the following.

Why your vehicle needs an air oil separator

Blow-by gases, especially for turbocharged engines can amount to as much as one litre of oil per 100km when the engine and engine oil are not maintained properly. If the gases are not actively separated from the oil in the intake, the oil can be burnt back into the engine again and this soiled mixture can damage the intake valves as well as reducing efficiency. By keeping these gases separate before they return to the intake, the air oil separator significantly helps to optimise engine performance.
In addition, there’s an air oil separator that keeps the emissions low. The cleaner the air going into the engine, the cleaner the exhaust that results. Not only are you helping the planet meet a minimum standard of air quality, but your vehicle’s engine will thank you, too.
Morevover, an air oil separator helps to keep your engine components running for a long time. Oil can be left from your vehicle’s engine and contribute to the wearing of its parts. If the intake system is clean, the air oil separator helps to lengthen the lifespan of your car’s engine and save you from additional expenses in the future.
How does an air oil separator work?
![Various-automotive-filters-and-a-liter-bottle-of-motor-oil-1](https://img.baba-blog.com/2024/06/Various-automotive-filters-and-a-liter-bottle-of-motor-oil-1.jpg?x-oss-process=style%2Ffull)
An air oil separator is clever but simple: the air and oil vapours coming from the crankcase ventilation system get forced through a centrifugal or coalescing filter. The oil gets pushed out of the air and returned to the oil pan, while the air is pushed back into the intake system of the engine.
This takes place continuously and goes on as long as your engine is running.It is an excellent case of how a simple component can go a long way in keeping your vehicle in the pink of health, in this case, by maintaining the efficiency of your vehicle. Here is a real example of a process in your car that vehicle owners must know, for it gives a perspective on the need for maintenance and monitoring of the air oil separator.
But, furthermore, oil separators are built to work at these conditions and can be adapted to the operating conditions of all kinds of engines, whether it’s for a race car or a daily commuter.
Common issues with air oil separators

And air oil separators can develop problems, just like other components. For example, they can clog. The filter or centrifuge portion of the separator can become blocked by residual oil and other debris over time, which reduces its effectiveness. This can lead to higher oil consumption, higher tailpipe emissions, and potentially engine damage if not maintained.
A second concern is leaks. The housing or connections of the air oil separator can begin to leak, causing a loss of efficiency, while possibly contaminating the engine bay. Regular checks can spot these issues before they become bigger troubles.
Finally, and perhaps most importantly, a dying air oil separator will result in either a fluctuating idle or a poor overall engine performance. As the efficiency of the part is reduced, so too – and frustratingly – is the reading of the air-to-fuel ratio.
Maintenance tips for your air oil separator

Proper maintenance of the vehicle’s air oil separator contributes to the smooth operation of the engine. To do so, the component must be checked regularly for clogging and damages. The owner’s guide for each vehicle indicates the specific inspection intervals, but in general, the air oil separator should be inspected with every oil change.
Purging or replacing the air oil separator as needed should avoid most of the issues above. Some air oil separators are reusable, reinstalled after being cleaned, while some need to be replaced entirely. For that, it’s important to know the specifications of your vehicle’s air oil separator.
Moreover, preventative maintenance will save you from expensive repairs. With increased oil consumption, smoke from the exhaust or diminished performance, it may be time to check the air oil separator.
The impact of an air oil separator on vehicle performance

It cannot be denied that having an effective air oil separator properly doing its work does help a vehicle performance as far as only clean air goes to the combustion chamber. Power output and engine efficiency remain constant without any degradation from the contaminants. This way, the engine runs more smooth and fuel economy is appreciated too once the filthy (contaminated air) is filtered out from the oil circuit.
Besides that, it also has a great deal to do with emissions. By learning how to optimize the oil separator, meeting strict environmental requirements becomes easier if your vehicle has a high-performance air oil separator which benefits to the general environment.
To sum up, it might be a small part, but the air oil separator is a crucial one for the life of your car. Understanding its role, problems it can cause, and how to maintain it can help vehicle owners to keep their cars running efficiently and reliably for years to come. This can really help in reducing environmental impact, and even helping your car to perform at its best.
