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 grille shutter control device of a vehicle includes an encapsulation structure covering an engine, a grille shutter provided at an opening formed at a front wall portion of the encapsulation structure, an actuator configured to move the grille shutter to open/close the opening, and a controller configured to control the actuator. The controller determines whether or not heat damage occurs on a related component relating to the engine upon key OFF, closes the grille shutter upon key OFF in the case of determining that the heat damage will not occur, and opens the grille shutter upon key OFF in the case of determining that the heat damage will occur.

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.
