PURPOSE:To purify exhaust gas by allowing the exhaust gas supplied from an engine to pass through the liquid soap in a muffler through a buoy which follows to the water level. CONSTITUTION:Liquid soap is stored in a muffler 5, and the exhaust pipe of an engine 1 is connected to a buoy 3 which follows to the water level of the liquid soap through a rubber pipe 2. The exhaust gas discharged from the buoy 3 is discharged from exhaust outlets 7 and 8, after purified by passing through liquid soap. A dirty-water discharge part 6 is formed on the bottom of the muffler 5. |
