The air filter housing in a car is the part that contains the filter itself and is usually located in an easily accessible location in the car's engine. The filter housing is mounted on the engine's ventilation box and has a cover that can be opened to access the filter and change it when needed.
Air filter box function
Providing protection for the filter and holding it securely in place, the canister prevents unwanted air or large particles from entering the filter, keeping the filter working effectively and efficiently.
The air filter housing is designed to allow sufficient airflow into the engine while keeping debris and dirt out. Housing designs vary from vehicle to vehicle depending on the engine design and airflow direction.
When changing the air filter, you must open the filter housing lid and carefully remove the old filter. You can then install a new filter in the appropriate position and close the housing lid tightly.
You must follow the vehicle manufacturer's directions and instructions or consult your maintenance manual to change the air filter correctly according to your vehicle's specifications.
Air filter and fuel consumption
The air filter has a direct impact on a car's fuel consumption. When the air filter is clean and efficient, it allows sufficient fresh air to flow into the engine, effectively enhancing the combustion process in the cylinders and improving engine performance.
On the other hand, if the air filter is clogged or excessively dirty, it obstructs the flow of air to the engine and reduces the amount of oxygen available for the combustion process. As a result, an imbalance in the fuel-air mixture can occur, leading to excessive gasoline consumption and decreased engine performance.
Therefore, it is important to keep the air filter clean and change it according to the schedule recommended by the vehicle manufacturer. It is recommended to check, clean, or replace the air filter regularly to ensure proper airflow to the engine and maintain vehicle performance and fuel efficiency.
Driving without an air filter
It is not recommended to operate or drive your vehicle without an air filter. The air filter cleans the air entering the engine of impurities, dust, and harmful particles.
If you operate your vehicle without or remove an air filter, it exposes the engine to many risks, including:
- Impurity ingress: Without an air filter, impurities and dust can enter the engine directly. These particles can damage internal engine parts, such as cylinders, valves, and valves, causing wear and reducing engine life.
- Performance Damage: Unfiltered air intake affects the air-fuel mix in your engine. This can lead to inefficient combustion and reduce engine efficiency and overall performance.
- Increased fuel consumption: When there is an imbalance in the air-fuel ratio, fuel consumption can increase significantly. This means you'll spend more money on fuel and reduce fuel efficiency.
- Damage to sensors and other parts: Unfiltered air can damage sensitive engine sensors and other measuring devices, and may also damage other parts of the combustion and ventilation system.
Does the air filter affect the temperature of the car?
The air filter itself does not significantly affect the temperature of the car. Its main function is to purify the air entering the engine, not to control the temperature of the car.
However, it should be noted that the air filter can affect airflow to the engine, so any impact on airflow can affect engine temperature. If the air filter is clogged or damaged, it can reduce the flow of cool air to the engine, which can lead to overheating.
Furthermore, if there is a malfunction in the cooling system or other parts related to engine temperature control, it may affect the car's temperature.
How to change the air filter?
The case may be located on the top or side of the engine, and is usually covered with a plastic cover.
- Disconnect the negative cable from the battery for safety. Disconnect the negative cable from the battery before starting the air filter change process. This helps avoid an electrical short circuit.
- Removing the cover: Open the air filter housing cover using appropriate screwdrivers or appropriate pry tools. There may be clips or screws that need to be removed to open the cover.
- Removing the old filter: Remove the old filter from the filter housing. It may be cylindrical or rectangular and packed with filter fibers.
- Cleaning: If the air filter is reusable and does not need to be completely replaced, you can carefully clean it with compressed air or with a special air filter cleaner.
- Installing the new filter: Install a new air filter into the filter housing, making sure it fits perfectly into the designated position and is securely attached.
- Reinstall the cover: Reinstall the air filter housing cover and tighten it securely.
- Reconnect the negative cable: To the battery: Reconnect the negative cable to the battery.
How often should the car air filter be changed?
Most manufacturers recommend changing your car's air filter between 10,000 and 20,000 kilometers (6,000 to 12,000 miles), or once a year, depending on usage and driving conditions. However, air filter replacement recommendations can vary between vehicles depending on the model and brand.
What are the signs of filter damage?
A damaged car air filter can cause several signs that indicate it needs to be replaced. Here are some common signs of a damaged air filter:
- Increased fuel consumption:
- If your air filter is clogged or dirty, it restricts airflow to the engine, which can lead to increased fuel consumption. If you notice your car consuming more fuel than usual, it could be the result of a damaged air filter.
- Degraded Engine Performance: When there is a lack of fresh air flow to the engine due to a damaged air filter, this can affect overall engine performance. You may experience a loss of traction or a delayed response when you press the accelerator pedal.
