Abstract
PURPOSE: To surely feed a prescribed quantity of secondary air in total range of load, by connecting a secondary air feed passage fitted with a check valve, to a port provided in a part facing the peripheral part of the exhaust side of impeller of an exhaust turbine.
CONSTITUTION: Since impulse takes place at the time of entry of exhaust gas into the gap between the vanes of impeller 5' of an exhaust turbine 5 or reaction takes place at the time of leaving of the exhaust gas from the gap between the vanes, a region of negative pressure lower than the atmospheric pressure is produced on the back of each vane by the flow of the exhaust gas on the front of the vane and the rotation of the impeller 5'. The region of negative pressure faces a port 17 provided in a part around the impeller 5' and causes pulsation because the rotation of the impeller. Only when the pressure in the port 17 is negative, a check valve 20 is opened to repeatedly suck secondary air from a secondary air feed passage 19 to sequentially supply the secondary air to an exhaust system.
