Abstract
An object of the present invention is to provide a construction for exhaust emission control, which can prevent thermal deterioration in a catalyst and can heat exhaust gas to a catalyst activation temperature. In the present invention, an electrically heated catalyst portionis provided in a separatorin a silencerlocated at a distance from an engine. This electrically heated catalyst portionheats low-temperature exhaust gas to a catalyst activation temperature. The exhaust pipebranches into three pipesandin the silencerThe electrically heated catalyst portionhas a shape surrounding the each outer peripheral surface of pipeandof an exhaust pipeExhaust gas is warmed to a temperature close to the catalyst activation temperature when it flows in the pipesandand flows out of the pipeandSubsequently, the exhaust gas is heated to the catalyst activation temperature when it passes through the electrically heated catalyst portion
