Claims

[Scope of utility model registration request]

In a turbocharger inflow foreign matter removal device configured to remove foreign matter in exhaust gas introduced from an exhaust manifold of an engine into an exhaust turbine housed in a turbine housing, the exhaust gas inlet portion of the turbine housing and the exhaust gas A curved duct formed by a guide plate and a duct wall is provided between the manifold and the exhaust gas flow so that the flow of the exhaust gas can be deflected twice, and the A foreign matter accommodating portion is provided at the direction of the first deflection direction of the gas flow, and an exhaust gas introduction passage to the exhaust turbine is provided at the direction of the second deflection direction of the exhaust gas flow. Features: Turbocharger inflow foreign matter removal device.
