とを特徴とした自動車等の排気装置。 In an exhaust system device such as an automobile equipped with a warm-up catalytic converter upstream of the main catalytic converter in the exhaust system, a bypass passage 2 is provided so that exhaust gas flows backward without passing through the catalyst of the warm-up converter 1. Additionally, an exhaust system for an automobile or the like is characterized in that a valve 3 driven by a shape memory alloy switches the flow of exhaust gas between a warm-up catalyst direction and a bypass direction.
