Abstract
Disclosed herein is a technique for providing an engine supercharger of a reduced size allowing an exhaust gas to be introduced smoothly into a turbine scroll. A turbine for use in this supercharger includes: a turbine lead-in route, into which the exhaust gas is introduced; a turbine scroll formed continuously with the turbine lead-in route to allow the exhaust gas to swirl around inside; a turbine wheel to turn on an axis of rotation; a turbine lead-out route; a wastegate passage to bypass the exhaust gas around the turbine scroll; and a wastegate valve. The turbine lead-in route includes a throat portion having a tapered downstream portion. The wastegate passage branches from that throat portion.
