Driving with a dirty air filter can have serious repercussions for both your vehicle and your health. An air filter is an essential component of the internal combustion engine, as it allows the engine to mix the right amount of air and fuel for proper ignition. Most manufacturers recommend replacing the air filter every 12,000 miles (approximately 19,000 km) or every 12 months, whichever comes first. However, if you live in an area with a lot of dust or impurities in the air, you should consider replacing your air filter more frequently.
If you drive with a dirty air filter, you may start to notice that the engine starts abruptly, does not work, or stops abruptly. This is because the lack of clean air can cause the gas to not burn completely during the combustion process. The unburned fuel then exits the vehicle through the exhaust pipe in the form of black smoke with soot or flames at the end of the exhaust pipe. In addition, carbon deposits can build up in the engine, which will eventually activate the check engine light.
Another consequence of a dirty air filter is reduced engine performance. The restriction in air flow forces the entire engine to run at low power to maintain the stoichiometric fuel ratio. If you drive a vehicle with an older carburettor, a decline in fuel economy is a common sign that the air filter is dirty. In addition to these problems, driving with a dirty air filter can also cause coughing or clicking noises coming from the engine compartment, or excessive vibration.
If you start to experience any of these symptoms, it's important to have your mechanic scan your vehicle to locate the source of the problem. It could be as simple as replacing the air filter. The location of an air filter may vary between models, but it can usually be easily accessed from the front of the engine block, connected to the intake pipe. Regularly replacing and servicing your air filter helps reduce the risk of any problems occurring in the near future. The risks associated with driving with a dirty air filter are real and should not be taken lightly.
It's important to replace your air filter regularly and inspect it for any signs of damage or dirt buildup. Doing so will help ensure that your vehicle runs smoothly and efficiently.
