Blocked Car Engine Air Filter – Replacement & Repair in Hamilton

About the air filter:

Inside your car’s petrol or diesel engine, a mixture of air and fuel is burnt. This combustion process gives your car’s engine the power to run. The air is introduced to the petrol or diesel engine through the engine air filter, whereas the fuel is introduced via the fuel injectors or carburetor (in older vehicles).

As air enters your petrol or diesel engine, it passed through the air filter. The air filter is made out of fibrous materials which help it to capture dirt, dust, pollen and other contaminants. This prevents the contaminants from entering your engine and doing damage.

When to replace the air filter?

The air filter picks up a lot of debris over time. This can cause it to become blocked eventually. A blocked air filter will need to be replaced or it will limit the amount of air that reaches the engine, resulting in reduced air flow into the petrol or diesel engine and a richer fuel mixture. Most mechanics recommend that you replace the air filter every 15,000-20,000 km.


Symptoms of a blocked air filter:

A blocked air filter may show the following symptoms:

Check engine light – If not enough air is getting to your engine, the Mass Air Flow meter and other sensors in your car will detect the difference. This can cause the check engine light to turn on.

Increased fuel consumption – less air for the same amount of fuel will give your engine less power and this will cause your car’s fuel consumption to increase to achieve the same vehicle speeds. 

Black smoke from exhaust – A rich fuel mixture will often result in fuel not burning correctly. The unburnt fuel can leave your exhaust in the form of black smoke. 

Popping sound from exhaust – When unburnt fuel flows through your exhaust, the high exhaust temperatures can often cause the fuel to reignite. This results in loud popping noises.
