Abstract
In a turbine housing of a twin entry type turbocharger, a first scroll chamber communicating with a first exhaust manifold, and a second scroll chamber communicating with a second exhaust manifold are provided. A surface area of the first exhaust manifold is configured to be larger than a surface area of the second exhaust manifold, and these exhaust manifolds are cooled by a cooling mechanism. In the turbine housing, a first and second cooling water passages are respectively provided to cover the first and second scroll chambers. An internal combustion engine includes a cooling device that causes cooling water to flow into the first and second cooling water passages, and the cooling device is configured so that a temperature of the cooling water that is introduced into the second cooling water passage becomes lower than a temperature of cooling water that is introduced into the first cooling water passage.
