What Do Air Filters Do?This isn’t a trick question. The purpose of an Air Filter is to filter the air. Air must be clean before it mixes with the fuel and burns in the cylinders of an engine. Unfiltered air contains all sorts of dirt and debris. Think of all the grass and dirt that flies around as you mow your lawn. You certainly wouldn’t want any of those particles to enter the internal parts of your engine. So what are some symptoms you can detect if your air filter is too dirty?
Symptoms of a Dirty Air Filter
Dirty air filter = decreased airflow = less power A clogged air filter covered in oil and dirt will smother your engine, not allowing the proper amount of air to burn with the fuel. Less combustion power means less horsepower. If you notice your mower is not maintaining consistent power, check your air filter.
More Fuel Consumption
If you’re not getting as much run time out of your equipment as normal, it may be the dirty air filter that’s causing your engine to consume more fuel. Your engine is trying to compensate for the loss of performance by burning more fuel.
Air, Fuel, and Spark. Without one of these components your engine will never start. So, if your air filter isn’t providing the right amount of air flow into the mixture, your equipment will stall, surge, and sputter as it gasps for air.
Damaging Effects of a Worn Out Air Filter
Holes in the air filter allow harmful debris to enter the carburetor.Dirty air filters can lead to worn out air filters. Holes in the fibrous material or cracks around the edges of the filter may form, allowing the dirt and debris to enter the parts of your engine. If your engine is exposed to these debris particles, it will cause premature wear to the internal parts of your engine, including the pistons, cylinders, and carburetor. So what do you think is cheaper, rebuilding/replacing the engine or changing a dirty air filter? Go with the air filter.
