PROBLEM TO BE SOLVED: To provide a constitution which can prevent that an EGR gas is discharged together with condensed water, in a condensed water discharge device for discharging the condensed water which is produced in a gas passage of an internal combustion engine.SOLUTION: A cyclone trapper 71 is arranged in an intake passage 11a, and condensed water which is produced by the condensation of a water component contained in an EGR gas is collected by the cyclone trapper 71. A condensed water tank 72 is integrally formed at a lower part of the cyclone trapper 71, and a pump dispenser 73 is connected to the condensed water tank 72 via a discharge pipe 74. A dispenser inner-pressure switching valve 76a which switches the introduction and non-introduction of supercharged pressure with respect to the inside of the pump dispenser 73 is arranged. When the switching valve 76a is opened, and a condensed water storage amount in the condensed water tank 72 reaches a prescribed amount, the switching valve 76a is closed, and the condensed water in the condensed water tank 72 is discharged to the pump dispenser 73 via the discharge pipe 74.SELECTED DRAWING: Figure 1 |
