PROBLEM TO BE SOLVED: To surely remove condensed water in an exhaust gas by a simple constitution.SOLUTION: When the exhaust gas discharged from an engine 1 reaches a swirl flow generation part 20 via exhaust pipes 5a to 5c, a swirl flow which forms a spiral shape toward the downstream side is created at a flow of the exhaust gas, and flows into a condensed water trap part 30. When the swirl flow of the exhaust gas flows into the condensed water trap part 30, in the condensed water trap part 30, a water component (condensed water) contained in the exhaust gas is separated by a centrifugal force of the swirl flow which swirls to the radial direction, and collected. At this time, heat from an exhaust manifold 4 which is heated by the high-temperature exhaust gas is transmitted to the condensed water trap part 30 via a heat transmission part 40, and the condensed water collected at the condensed water trap part 30 is evaporated by the heat. By this, the condensed water in the exhaust gas can be surely removed by the simple constitution, and a malfunction such as the corrosion of the exhaust pipe caused by a component contained in the condensed water can be prevented. |
