Abstract
In an exhaust gas control system for an internal combustion engine, addition valves which add an additive toward a first selective reduction NOx catalyst are provided in an exhaust passage on both of an upstream side and a downstream side of the SCR catalyst. In a case where a flow rate of exhaust gas flowing in the exhaust passage is equal to or lower than a predetermined flow rate, the additive is added from both addition valves to allow ammonia to be adsorbed onto the first selective reduction NOx catalyst.
