EXHAUST GAS CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

摘要

A bypass passage (7) is provided, which connects a portion upstream of a turbine (5b) of a supercharger (5) in an exhaust passage (3) to a portion close to a front end surface (4a) of exhaust gas purification means (4) in the exhaust passage (3), and through which at least part of exhaust gas discharged from an internal combustion engine (1) flows. The exhaust gas discharged from the bypass passage (7) is blown to the front end surface (4a) of the exhaust gas purification means (4) in a lateral direction of the front end surface (4a), whereby particulate matter deposited in the front end surface (4a) of the exhaust gas purification means (4) is blown off.
