摘要： An exhaust purification system includes an oxidation catalyst disposed in an exhaust passageway of an engine, and a filter disposed downstream of the oxidation catalyst in the exhaust passageway. The exhaust purification system further includes an outlet temperature setting section for setting, as an outlet target temperature, a target value for an exhaust temperature which is detected on the downstream side of the filter in the exhaust passageway. The system further includes a heat loss quantity computing section for computing a heat loss quantity radiated from the filter to outside the exhaust passageway when exhaust discharged from the engine passes through the filter; and an inlet temperature setting section for setting, as an inlet target temperature on an upstream side of the filter, a temperature obtained by adding a loss temperature reduced by the heat loss quantity to the outlet target temperature.
