摘要： An exhaust emission control device includes an adsorbent trapper having an adsorbent for adsorbing and desorbing hydrocarbon in exhaust gas, a catalytic converter, a main exhaust gas passage with a first valve, a bypass exhaust gas passage with a second valve and a control unit. The bypass exhaust gas passage bypassing the first valve is connected with the adsorbent. The control unit controls the first and second valves to desorb the hydrocarbon from the adsorbent when a condition is satisfied. The condition is that the catalyst converter is in active, an oxygen adsorption amount of the catalyst converter is not less than a first predetermined amount and an exhaust gas amount is not more than a second predetermined amount. The first valve is opened and the second valve is closed when the condition is not satisfied during desorption of the hydrocarbon from the adsorbent.

摘要： An exhaust manifold includes a plurality of branch pipes 2 to 5 and an adapter member 9 that has a ring portion 10 provided at exhaust-gas downstream side end portions 2a to 5a of the branch pipes 2 to 5 and with a reinforcement portion 11. The adapter member 9 and the exhaust-gas downstream side end portions 2a to 5a, which are inserted into the adapter member 9, are fixed with each other by a circular weld line X1 formed along outer circumferences of the exhaust-gas downstream side end portions 2a to 5a of the branch pipes 2 to 5 and also by a weld line X2 formed along the adjacent side wall portions 2b to 5b of the branch pipes 2 to 5.
