Abstract: Provided is a thermally insulated insert member and an engine having the thermally insulated insert member. Thermally insulated insert member is disposed in an intake port of a cylinder head of the engine. The thermally insulated insert member includes a guide member that guides a flow of intake air flowing in t he intake port; and a thermally insulative support member with a shape that can be fitted within the intake port. The guide member is formed of a metal and is supported in the intake port via the thermally insulative support member.

Abstract: In an intake device for an internal combustion engine, a difference in the air-fuel ratio between the cylinders is reduced without increasing the lengths of the branch passages. An intake device (23) for an internal combustion engine (1) having at least three cylinders (3) includes: an intake chamber (30) configured to be connected with an air inlet (16); and multiple branch passages (31) connected at upstream ends (41) thereof to the intake chamber and connected at downstream ends thereof to intake ports (6) communicating with the cylinders, respectively, wherein the upstream ends of the branch passages are arranged in a direction of rotation about a predetermined center line X in a same order as an order of ignition of the cylinders.
