Abstract

Official abstract text for this publication.

An exhaust gas control apparatus ( 100 ) of an internal combustion engine ( 200 ) of a vehicle, which is provided with: the internal combustion engine which can use fuel containing methane in exhaust gas; an exhaust gas purifying apparatus ( 300 ) disposed in an exhaust passage of the internal combustion engine; an EGR passage ( 400 ) which can recirculate the exhaust gas to an intake passage of the internal combustion engine, in a HPL path which does not include the exhaust gas purifying apparatus; and an adjusting device ( 407 ) which can adjust an exhaust gas recirculation amount in the EGR passage, is provided with: a first specifying device for specifying a methane concentration in the exhaust gas; and a first controlling device for controlling the adjusting device to increase an exhaust gas recirculation amount in the HPL path if the specified methane concentration is greater than or equal to a reference value.

First claim
