摘要：
A condensed water treatment device determines whether a storage water quantity Qw of condensed water generated in an EGR cooler and stored in a condensed water tank is equal to or less than a lower limit t1 (S2). When the storage water quantity Qw is equal to or less than the lower limit t1, the flow rate of the EGR cooler is set to 100% and the flow rate of a bypass passage is set to 0% (S3), whereby supply of condensed water to an internal combustion engine is stopped (S5). Thereby, the condensed water treatment device increases the storage water quantity Qw. While, when the storage water quantity Qw is more than the lower limit t1 and also equal to or more than the upper limit t2, the flow rate of the EGR cooler is set to 0% and the flow rate of the bypass passage is set to 100% (S7), whereby supply of condensed water to the internal combustion engine is executed (S9). Thereby, the condensed water treatment device decreases the storage water quantity Qw.
摘要（中）：
冷凝水处理装置判定在EGR冷却器中产生的冷凝水中存储的冷凝水的储存水量Qw是否在下限t1以下（S2）以下。 当储水量Qw小于下限t1时，将EGR冷却器的流量设定为100％，将旁通通路的流量设定为0％（S3），由此， 停止向内燃机的水（S5）。 由此，冷凝水处理装置增加蓄水量Qw。 而当储水量Qw大于下限t1并且大于上限t2时，EGR冷却器的流量设定为0％，旁路通道的流量设定为 100％（S7），由此执行向内燃机供给冷凝水（S9）。 由此，冷凝水处理装置减少储存水量Qw。
