Why is there water in the car air filter?

[SanEthan]

Water may accumulate in the air filter due to humid conditions or when the vehicle passes through water. Below are the relevant explanations: 1. Air Filter: An air filter is a type of filtration device, also known as an air filter cartridge, air cleaner, or air element. It is primarily used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operation rooms. 2. Principle: During operation, the engine needs to intake a large amount of air. If the air is not filtered, the dust suspended in the air that is drawn into the cylinders can accelerate the wear of the piston assembly and cylinders. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring," which is especially problematic in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles from the air, ensuring that sufficient and clean air enters the cylinders.
