Title: Exhaust device for engine with pressure wave supercharger
Inventor: KIMURA KIYOMI
IPC: F01N3/20
Filed: 1990-07-20
Abstract: PURPOSE:To promote activating of a catalyst and improve emission property by providing a catalyst for purifying exhaust on the exhaust passage of an upstream side more than a pressure wave supercharger, and mounting the catalyst at a position in close proximity to the outlet/inlet side of exhaust discharged from the pressure wave supercharger. CONSTITUTION:Since a catalyst 18 is arranged on the upstream side more than a pressure wave supercharger 5, purifying of exhaust is carried out without meeting with any resistance at the time of scavenging of exhaust gas in the pressure wave supercharger 5, and without interference with operation of the pressure wave supercharger 5. Since the catalyst 18 is mounted at a position in close proximity to a gas casing 5b side which is positioned at a high temperature side of the pressure wave supercharger 5, radiant heat supplied from the high temperature part of the pressure wave supercharger 5 is utilized effectively when the catalyst 18 is at a low temperature in the case of engine startup or the like, so that it is possible to accelerate rising in the temperature of the catalyst 18. It is thus possible to promote activating of the catalyst 18, and purifying of exhaust is early carried out after startup so as to improve emission property.
