ABSTRACT:
An exhaust gas control apparatus for an internal combustion engine includes an exhaust gas purification catalyst device provided in an exhaust passage for the engine; an HC adsorption portion, provided in the exhaust passage, which adsorbs hydrocarbon in exhaust gas; a passage switching portion that selectively closes/opens a second passage bypassing the HC adsorption portion using an intake pipe negative pressure in the engine so that the exhaust gas flows in a first passage provided with the HC adsorption portion, or in the first passage and the second passage; and a control portion that controls the negative pressure so that the second passage is closed, when a predetermined condition is satisfied at the time of start of the engine. The control portion executes at least one of a control that advances the valve timing of an intake valve, and a control that reduces the opening amount of a throttle valve.
