ENGINE WITH SUPERCHARGER

摘要

An object is to provide a supercharged engine capable of achieving a temperature of exhaust gas necessary to activate a catalyst used by an emission control device, without having the specifications of the supercharged engine changed. A supercharged engine (6) includes an emission control device (50) configured to add a reduction agent to exhaust gas from an engine main body (40) to reduce nitrogen oxide in the exhaust gas by a catalyst, the supercharged engine including an air release valve (70) configured to discharge a part of supplied air to be supplied from a supercharger (20) to the engine main body (40) through an air feed pipe (28) to the outside of the air feed pipe (28), and a control device (80) configured to control temperature of the exhaust gas by operating the air release valve (70) and adjusting an amount of supply of the supplied air to be supplied from the supercharger (20) to the engine main body (40).
