Abstract
Dispositif permettant de réduire les émissions de gaz nocifs, dans les moteurs à essence quatre temps à combustion interne par amortissement de la dépression dans le boîtier d'admission. Il comprend deux demi-sphères 2 et 3, une membrane 1, deux tuyaux métalliques piqués diamétralement 4 et 5 sur les demi-sphères un T de raccordement. L'invention peut être utilisée dans tous les cas du moteur à essence quatre temps pour réduire la pollution et les bruits d'admission.
