A car air filter role is to clean the air entering the vehicle engine. Signs of a dirty or dull air filter comprise a misfiring engine, uncommon noises, and low fuel economy.

 

A vehicle or car engine combines air and gasoline in the combustion chamber to produce power. So this air instantly reaches the vehicle engine by an air filter that works to keep away road rubbish, dust, bugs, and other pollutants that can harm the car engine. In the meanwhile, the filter must let enough air to reach the vehicle engine so that it can perform efficiently. In Over time, the air filter can become dull and clogged, and the lack of air can affect the total performance of your vehicle.

 

Almost every automotive industry or companies suggest that you must the change the filter after 10k to 15k miles, or after the year. But if you drive the car in the rural or dusty areas than you should consult your mechanic and change it more frequently of after 5000 miles. In crowded and dusty Areas where you have to stop and start the vehicle again and again need to change the air filter more frequently.

Below are some the symptoms or signs which indicate that air filter need to change.

Low fuel economy

Your vehicle engine compensates for lower sums of oxygen by consuming more oil to generate sufficient power. So if you observe that your fuel economy is reducing, it could be an sign that the air filter wants changing. Though, this is proper only for carburetor car, most of which were made before 1990. Latest vehicle with fuel-injected car engines have on-board system which compute the amount of air occupied into the engine, and regulates the fuel flow consequently. That’s why the cleaning of the air filter on new cars shouldn’t significantly disturb fuel economy.

Misfiring of engine

Imperfect supply of air from a muted air filter cause in unburnt fuel exiting the engine in the form of soot residue. This soot collects on sparking plug, in return it can’t deliver the essential spark to combust the air-fuel mix. You’ll see that the engine does not start up effortlessly, misfires, or jerks unevenly.

Uncommon sound from Engine

In usual conditions, the moment when your vehicle is standing with the engine on, you should feel the even rotation of the car engine in the system of subtle vibrations. But if you feel your vehicle vibrant extremely or hear a popping or sound like coughing, it is often due to a dull or injured spark plug resulting from an air filter which has clogged.

Check the Engine Light

Most of the car engines suck up about 12,000 gallons of air for every single gallon of oil or fuel burned in the combustion cycle. Insufficient supply of air can cause in carbon deposits collecting in the engine which may set off the Check Engine Light. If that occurs, you have to mechanic check the air filter among other diagnostics.

Air filter appears dirty

A clean air filter color should be white or off white, but within the passage of time it collect the dirt and dust and change into darker color.

Though, frequently, the inside layers of filter paper inside the air filter might have dirt and debris that is not noticeable even in brighter light. Therefore, it is important that you have your car mechanic check the air filter when you take the car for maintenance. Make sure to read the manufacturer’s manual book regarding replacement.

Issue in horsepower

If your vehicle does not respond sufficiently or if you feel jerking activities when you put the force on the accelerator, this could indicate that your engine is not receiving all the air it needs to perform. Changing your air filter of car can better acceleration or horsepower by up to 20%.

Black smoke or flames

An insufficient air supply can cause in some of the fuel not burning totally in the combustion cycle. This unburnt fuel or oil then exits the car through the exhaust pipe. If you notice the dark black smoke release from your exhausting pipe, ask you mechanic to change the air filter. You might also notice the popping sounds or see a blaze at the close of the exhaust. This occurs when the warmth in the exhaust system ignites burnt oil or fuel close the tailpipe. This is a possibly dangerous condition and needs to be analyzed right away.

Gasoline Smell

If there isn’t sufficient oxygen inflowing the carburetor or the fuel ejection system when you twitch the car, the extra unburnt fuel exits the car by the exhaust pipe. That’s why when you’ll odor the gasoline and see that it’s spell to change the air filter.
