摘要：
In an embodiment of an exhaust gas purification apparatus, when an accumulation amount of particulate matter in a DPF (33) exceeds a predetermined amount and an exhaust gas temperature of an engine is lower than a restoration operable temperature, an intake air amount reducing operation is executed by an air intake throttling device (24) provided for an air intake pipe (21) of the engine, and a heating operation is executed by an electric heater (34) provided upstream from the DPF (33), thereby increasing the exhaust gas temperature to the restoration operable temperature to start a restoration operation of the DPF (33).
