"textContent": "An exhaust emission control device comprises an oxidizing catalyst (43), a particulate filter (44) on which soot is deposited, and a temperature sensor (53) for detecting the temperature of exhaust gas on the upper-stream side of the filter (44). An intake system (13) of an engine (11) is provided with an EGR valve (23) for returning the exhaust gas to the intake system (13). If the temperature of the oxidizing catalyst (43) is found to be lower than its active temperature as the particulate filter (44) is regenerated, the catalyst (43) is heated by delaying the injection timing for the main fuel injection of the engine (11) and increasing the EGR gas reflux quantity. Thus, the oxidizing catalyst (43) can be heated up without lowering the fuel-efficiency, and soot on the particulate filter can be efficiently subjected to re combustion.",
