Claims

[Scope of utility model registration request]

A catalytic converter is provided between a plurality of exhaust inlet pipes and a single exhaust outlet pipe to purify exhaust gas. A downstream pipe connected to the outlet pipe and housing a secondary catalyst therein, and a casing covering the upstream pipe and the downstream pipe to form an exhaust gas passage outside these pipes,
The upstream pipe and the downstream pipe are arranged such that the outlet part of the upstream pipe is close to the connecting part of the downstream pipe and the exhaust outlet pipe, and the inlet part of the downstream pipe is close to the connecting part of the upstream pipe and the exhaust inlet pipe. arranged adjacent to each other,
Exhaust gas flowing into each of the exhaust inlet pipes passes through the primary catalyst, passes from the outlet of the upstream pipe, passes through the exhaust gas passage, merges at the inlet of the downstream pipe, passes through the secondary catalyst, and then exits the exhaust gas. A catalytic converter characterized by discharge into a pipe.
