た内燃機関の排気消音装置。 A muffler is installed on the exhaust path of an internal combustion engine and performs exhaust noise silencing processing, a filter that allows the exhaust flow from the muffler to pass through and captures exhaust particulates in the exhaust, and a filter that branches off from the exhaust path on the upstream side of this filter. Exhaust silencing for an internal combustion engine, comprising a bypass passage extending from the bypass passage, a bypass muffler for silencing and discharging the exhaust flow in the bypass passage, and a bypass valve for selectively guiding exhaust gas to the bypass muffler and the filter. Device.
