<p>An exhaust system ( 1 ) is provided with an exhaust passage that allows exhaust gas discharged from an internal combustion engine to pass therethrough, an exhaust emission control unit including a catalyst ( 2,3 ) such as a three-way catalyst ( 27 ) to purify the exhaust gas, and an exhaust heat collecting unit that converts thermal energy of the exhaust gas into electric energy. The exhaust passage ( 25 ) is formed in the center of the exhaust system provided with the exhaust emission control unit. By-pass passages ( 26 ) are formed at both sides of the exhaust passage ( 25 ) through which the exhaust gas flows without passing through the exhaust emission control unit. The exhaust heat collecting unit ( 29 ) is provided on the outer side of each of the by-pass passages ( 26 ).</p> |
