PROBLEM TO BE SOLVED: To provide a muffler for an exhaust device, especially of an automobile with a hybrid driving device.SOLUTION: A muffler for an exhaust device of an internal combustion engine, especially for an automobile with a hybrid driving device, comprises a heat exchanger unit (48) arranged in a muffler casing (12), an inflow pipe (38) for leading combustion exhaust gas into the muffler casing, a first outflow pipe (52) for leading out the combustion exhaust gas from the muffler casing, a second outflow pipe (40) for leading out the combustion exhaust gas from the muffler casing, and a flow passage opening/closing unit (58). In the muffler casing, a first exhaust gas flow passage (54) is provided for guiding the combustion exhaust gas to the first outflow pipe through the heat exchanger unit. In the muffler casing, a second exhaust gas flow passage (56) is provided for guiding the combustion exhaust gas to the second outflow pipe while bypassing the heat exchanger unit. At least one exhaust gas flow passage of the first exhaust gas flow passage and the second exhaust gas flow passage is selectively opened and closed by the flow passage opening/closing unit.SELECTED DRAWING: Figure 1

    【課題】特にハイブリッド駆動装置を備える自動車の排気装置用マフラを提供する。【解決手段】マフラケーシング(12)内に配置された、熱交換器ユニット(48)と、燃焼排気を前記マフラケーシング内へ導入する流入管(38)と、燃焼排気を前記マフラケーシングから導出する第1の流出管(52)と、燃焼排気を前記マフラケーシングから導出する第2の流出管(40)と、流路開閉ユニット(58)とを有し、前記マフラケーシング内に、燃焼排気を前記熱交換器ユニットを通して前記第1の流出管に案内するための第1の排気流路(54)が設けられており、前記マフラケーシング内に、燃焼排気を前記熱交換器ユニットを迂回して前記第2の流出管に案内するための第2の排気流路(56)が設けられており、前記流路開閉ユニットにより、前記第1の排気流路と前記第2の排気流路のうちの少なくとも1つの排気流路が選択的に開閉される。【選択図】図1
