An exhaust purification apparatus of an engine, which can release components of an exhaust efficiently by a regeneration process, is provided. In performing the regeneration process, the exhaust purification apparatus changes an interval (T1) between supplies of a fuel, as a reducing agent, by an injector (54) in accordance with a temperature difference (Te3) between the temperature (Te1) of an exhaust purification catalyst (52) and a set temperature (Te2). |
