Abstract: An exhaust gas recirculation (EGR) passage is connected with an intake passage (a bypass passage bypassing a supercharger) of an engine. The EGR passage includes, in a position close to a connection port to the intake passage, an expanding portion in which a passage cross-sectional area expands and which lowers a flow speed of EGR gas so as to reduce an uneven flow, in the connection port, of the EGR gas flowing into the intake passage.

Abstract: A heat insulating cover (cylinder-head-side heat insulating cover (30)) includes a top wall (31) and first side walls (32). The top wall (31) covers a top surface of an engine (1) that is a surface of an upper portion of the engine (1). The first side walls (32) cover respective upper portions of both side surfaces of the engine (1) in a vehicle width direction. A portion of the heat insulating cover closer to the rear of the vehicle is provided with a hinge mechanism (36) vertically rotatably supporting the upper portion of the heat insulating cover including the top wall (31). The upper portion of the heat insulating cover can be rotated, with the hinge mechanism (36) as a fulcrum, between a closed position where the engine (1) is shielded and an open position where the engine (1) is visible.

Abstract: A heat insulating structure of an internal combustion engine (engine 1) includes a cylinder-head-side heat insulating cover (30) and a cylinder-block-side heat insulating cover (40). Each of the first side walls (32) of the cylinder-head-side heat insulating cover (30) is disposed outwardly of, and is spaced apart from, a corresponding one of the second side walls (43) of the cylinder-block-side heat insulating cover (40) in the width direction of the vehicle. The lower edge of each of the first side walls (32) is positioned below the upper edge of the corresponding one of the second side walls (43) to overlap with the corresponding one of the second side walls (43) when viewed from the side of the vehicle.
