Where is the car air filter? How to change

The air filter of a car is the position of the air inlet of the car. It is a rectangular box with a plastic shell, and both ends have an interface connected with the air inlet pipe, one end is connected with the air inlet pipe, and the other end is connected with the throttle valve (to the engine).

When the engine is working, it will inhale a lot of air. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and the cylinder will cause a serious "cylinder pulling" phenomenon, which is especially serious in a dry and sandy working environment. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand in the air and ensure enough clean air to enter the cylinder.

Maintenance:

1. The filter element is the core component of the filter. It is made of special materials, belongs to wearing parts and needs special maintenance.

2. When the filter works for a long time, the filter element intercepts some impurities, which will lead to an increase in pressure and a decrease in flow. At this time, it needs to be cleaned up in time;

3. When cleaning, make sure not to deform or damage the filter element.

Generally speaking, the service life of the filter is different according to the different raw materials used, but with the extension of service time, impurities in the water will block the filter, so generally speaking, the PP filter needs to be replaced once every three months.
