Exhaust gas control apparatus for internal combustion engine

摘要

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