摘要: An exhaust gas control apparatus for an internal combustion engine, controls an exhaust operation of the internal combustion engine (200) provided with an exhaust gas purification catalyst (216) in an exhaust passage (215). The exhaust gas control apparatus for the internal combustion engine is provided with; a warming-up device configured to warm up the exhaust gas purification catalyst; and an oxygen supplying device (220, 221) configured to supply oxygen to the exhaust gas purification catalyst after the end of the warm-up. This makes it possible to preferably desorb sulfur adsorbed to the exhaust gas purification catalyst during warm-up. It is therefore possible to suppress a reduction in purification ability of the exhaust gas purification catalyst due to sulfur coating.
