Abstract
PURPOSE: To raise the emissions purifying performance of a catalyst and hold down the deterioration of the catalyst and the local temperature rise of a catalytic muffler as much as possible.
CONSTITUTION: Secondary air is supplied to the downstream side of the catalyst 3 provided in the catalystic muffler of an internal combustion engine to purify its emissions. Namely, the secondary air is introduced into the exhaust gas at the downstream side of the catalyst. The vibration of gas column in the flowing direction in the muffler is utilized to cause oxidation even at the downstream side of the catalyst. The dispersion of the oxidation in the catalyst under a large load and the starting of the oxidation under a small load are thus facilitated.
