L'invention concerne un appareil destiné à purifier l'admission d'air dans un moteur à combustion, dans lequel l'air introduit à partir d'un orifice d'admission d'air externe est purifié par une lampe à ozone disposée dans un logement de filtre, et à améliorer l'efficacité de réflexion UV-C par revêtement de composants de l'appareil au moyen d'un matériau inoxydant, ce qui permet d'améliorer la performance de purification de l'air. L'invention concerne également un appareil destiné à purifier l'admission de l'air dans un moteur à combustion interne comprenant : un filtre à air destiné à filtrer l'air introduit dans le moteur à combustion interne au moyen d'un photocatalyseur ; un logement de filtre destiné à recevoir le filtre à air ; et une lampe à ozone disposée en-dessous du filtre à air et dans la partie inférieure du logement de filtre à air afin de fournir un filtre à air doté d'une source de lumière UV-C. L'appareil de l'invention permet d'améliorer l'efficacité du moteur à combustion interne, et de fournir en continu de l'air purifié physiquement et chimiquement stable avec de l'ozone et des groupes hydroxyle au moteur à combustion interne, ce qui permet d'obtenir une admission d'air qui répond à un rapport de mélange théorique par rapport au moteur à combustion interne et qui contribue à une combustion complète et à une commande de combustion stable pendant le fonctionnement du moteur à combustion interne.
