4.10.3 Air filter
This is one of the simplest and at the same time irreplaceable car parts. Purpose of the air filter is cleaning from dirt and dust particles the air that comes from outside. In case if there was no filter, then the foreign particles that get inside would turn into "sandpaper", regularly tearing the cylinder face (we explained this in the section "Description of the Layout of the Basic Engine"). We should not explain what does this "processing" lead to. A schematic representation of the air filter body is shown in Figure 4.41.
