Abstract

The condensed water treatment device increases the EGR quantity (SS) so as to be larger than the EGR quantity (Qe) calculated based on the operating state, when within a specific time period (S) from a moment when execution of filter regeneration control is started to a moment after predetermined time has elapsed following the end of the execution, and also in a case where (S) the storage water quantity (Qw) of a condensed water tank storing condensed water generated in an EGR cooler is smaller than a normative water quantity (Qwt).
