ABSTRACT:
A secondary air supply device for introducing, by utilizing the exhaust gas pulsations, a flow of secondary air into the exhaust gas to after-burn the unburned combustibles comprises a secondary air supply conduit including an inlet section having a reduced flow area and an exit section having an enlarged flow area. This enables an increase of the frequency of resonance of the secondary air supply conduit without reducing the length thereof, so that the amplitude of the pressure pulsation in the secondary air supply conduit is extended to cause the pressure pulsation to occur at least in part in the negative pressure range at a high engine speed, thereby assuring the supply of secondary air even during the high speed operating condition of the engine.
