Abstract:
An exhaust gas control apparatus includes: a fuel injection valve configured to inject fuel into an internal combustion engine; a catalyst provided in an exhaust passage and configured to clean exhaust gas; a filter provided on a downstream side of the catalyst; a fuel introducing unit configured to introduce the fuel, which is injected from the fuel injection valve, into the exhaust passage from the internal combustion engine in an unburnt state; and a load control unit configured to control an upper limit of a load on the internal combustion engine. In the exhaust gas control apparatus, the load control unit is configured to set, when the fuel is supplied to the exhaust passage in the unburnt state, the upper limit of the load to a second limit value lower than a first limit value, which is an upper limit of the load before the injection.
