Claims

[Scope of utility model registration request]

In a heat insulator that covers the outside of an exhaust manifold in an internal combustion engine with a gap between the outside and the outside of the exhaust manifold, the heat insulator is located at a gathering point between the plurality of exhaust manifolds and actively collects running outside air. An exhaust manifold for an internal combustion engine, characterized in that an outside air introduction window is formed to introduce the outside air into the gathering part, and an exhaust port is formed downstream of the outside air introduction window to exhaust the introduced outside air to the outside. heat insulator.
