The Air Filtering Technologies for Motor Vehicles' Internal Combustion Engines

The air contains lots of impurities, of various sizes and different chemical compounds. The size of the dust particle that passes through the air filter influences the wear of kinematic couples inside the internal combustion engines. The paper presents the classical air filtering performances and the improvements brought by the new filtering technologies. The innovatory design of filtering system is absolutely necessary to rise the performances of the filtering and make an improvement of air flowing and forward increasing engine's life and performances.
