Abstract

An exhaust gas purifying apparatus includes an oxidative catalyst and a filter that are disposed in an exhaust gas path of an engine; a fuel injecting device that injects fuel according to a fuel injection pattern; and a control device that estimates a deposition amount of a particulate matter and sets the fuel injection pattern. When the fuel injection pattern including post-injection is set to recover the filter, the fuel injection pattern is set such that a post-injection amount is reduced as the deposition amount increases.
