Abstract

The condensed water processing device determines (S) whether the pH of condensed water stored in the condensed water tank is smaller than a threshold value (t). When the pH of condensed water is smaller than the threshold value (t), the supply quantity of urea water being supplied to the upstream side of the NOx catalyst is increased (S) so that the supply quantity is larger than that in normal control (S) executed when the pH of the condensed water is equal to or more than the threshold value (t).
