Where is the air filter located in the Honda CR-V?
1 Answers
It is located on the right side of the engine compartment. The commonly used air filters in engines mainly include the inertial oil-bath air filter, the paper dry-type air filter, and the polyurethane filter element air filter. Inertial Oil-Bath Air Filter: It undergoes three stages of filtration: inertial filtration, oil-bath filtration, and filter-type filtration. The latter two types of air filters mainly rely on the filter element for filtration. The inertial oil-bath air filter has advantages such as low intake resistance, adaptability to dusty and sandy working environments, and a long service life. It was previously used in various models of cars and tractor engines. However, this type of air filter has drawbacks such as low filtration efficiency, heavy weight, high cost, and inconvenient maintenance, and has gradually been phased out in automotive engines. Paper Dry-Type Air Filter: Made from resin-treated microporous filter paper, the filter paper is porous, loose, and folded, with certain mechanical strength and water resistance. It offers advantages such as high filtration efficiency, simple structure, light weight, low cost, and easy maintenance, making it the most widely used air filter in automobiles today. Polyurethane Filter Element Air Filter: The filter element is made of soft, porous, sponge-like polyurethane with strong adsorption capabilities. This type of air filter shares the advantages of the paper dry-type air filter but has lower mechanical strength and is widely used in passenger car engines. The drawbacks of the latter two types of air filters are their relatively short service life and unreliability under harsh environmental conditions.
