Oily air filter traps dirt

With the air filters installed, dirt, dust and leaves can’t get into your car’s engine and cause damage. A dirty oily filter can cause a lawn mower to malfunction.

It can prevent the mower from working properly, which might result in the engine not getting enough oxygen, or allow bad particles to pass into the engine causing it to break down. 

An air filter allows a good mix with gasoline and combust. However, when it becomes oily, it can do harm to the lawn mower engine by not allowing adequate airflow through the engine. 

A major problem with filters that are too oily or contaminated is that they can get stuck in the engine, where they allow unwanted small particles to enter. If this continues, the engine may stop functioning properly and the user will have to replace it.

Wrong procedures to maintain

When turning the mower over the wrong way, it becomes impossible to clean and the air filter gets dirty and oily. What’s worse is that if oil gets on the air filter and it gets too clogged, it will cause damage to the mower. 

But if you don’t change the air filter as soon as it gets dirty, then the engine will not be able to breathe and this can lead to an engine failure. To fix this issue, change the air filter.

Engine Misfires

A dirty air filter in your lawn mower can cause an engine misfire. When it is restricted from getting fresh air, the unburned fuel is forced into the cylinders where it can form a soot residue which blocks critical passages inside the engine.

The misfiring is also caused by an accumulation of dirt on the spark plug which can’t deliver enough combustion for optimum performance. Although there may be a lot of dirt in the air filter, the engine will still not perform well. 

This is because, in order to reach optimal performance, the spark plug needs to be clean. Changing the air filter regularly helps in maintaining this spark plug and prevents engine misfiring.

Poor engine performance

A clogged air filter in your lawn mower will cause poor engine performance and the engine to heat up quickly. Oil that has been spilled on the air filter will also not allow for proper combustion of fuel, creating a high level of unburnt fuel that will mix with dirty air. 

This buildup in your engine is likely to lead to any one of a number of different problems including reduced power and increased strain on the mower’s engine.

A clogged air filter will not only clog up the engine, but it will also smother your engine. It is important to be aware of how dirt from the air filter could kill your engine. 

It also prevents the fuel from burning with the right amount of air. The engine will fetch less combustion power that means less horsepower will be produced. And less engine performance.

In order to remove this problem, you need to remember that clean filters are crucial for optimal combustion, which allows for proper power usage and less wear and tear on your lawn mower. 

The best way is to replace the dirty air filter with a new one.

Causes Black Smoke

If a gas is not completely burned during the combustion process, it will result in black smoke or flames coming out of the exhaust pipe. As air is not clean, it will result in poor combustion. 

Black smoke is caused by fuel oil which has not been completely combusted during the combustion process. This is because of improper air filtration or too much fuel oil on the air filter. 

This leads to a build-up of tar particles which eventually coats the sides of the engine and prevents complete combustion of fuel.

Strong Fuel Smell

The quality of the air a vehicle produces can have a big impact on the engine’s performance. A dirty air filter can cause poor combustion and create black smoke. 

This will lead to a strong smell inside the car in addition to decreased fuel efficiency and increased emissions. With all of these factors considered, it is important to take care of the air filter regularly.
