An engine bay structure of a vehicle is provided, which includes a capsule cover surrounding an engine. The capsule cover includes a lid part configured to cover the engine from above and a side wall part configured to cover the engine from outside in a vehicle width direction. The side wall part is divided in a vehicle front-and-rear direction into a plurality of vertical walls extending in an up-and-down direction, and one of the plurality of vertical walls is a specific vertical wall to which an electric component is attached at a side surface part thereof opposite from the engine.

Engine bay structure of vehicle and method of assembling capsule cover

A vehicle is provided, which includes an engine bay having an upper wall, side walls, a front wall, and a rear wall, an engine disposed inside the engine bay, and a dedicated heat retention member provided inside the engine bay, the dedicated heat retention member comprising an upper lid part covering the engine from above to be openable and closable, and side-wall parts covering a side of the engine. A portion of the side-wall parts is comprised of an engine mount bracket configured to support mounts of the engine, instead of the dedicated heat retention member.

Engine heat retention structure

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

Heat insulating structure for internal combustion engine

A hybrid vehicle according to one aspect of the present invention is a hybrid vehicle including: an engine arranged at a vehicle body front portion; a propeller shaft configured to transmit an output of the engine to wheels arranged at a vehicle body rear portion; and a drive motor provided so as to drive the propeller shaft and supported with a vehicle body, and the propeller shaft transmits an output of the drive motor to wheels arranged at at least one of the vehicle body front portion and the vehicle body rear portion. The propeller shaft is supported with the vehicle body through the drive motor by a middle portion of the propeller shaft in the vehicle body front-rear direction being supported with the drive motor.

Hybrid vehicle and vehicle

A vehicle is provided, which includes an engine bay having an upper wall, side walls, a front wall, and a rear wall, an engine disposed inside the engine bay, an upper lid part disposed inside the engine bay and covering the engine from above, a shroud disposed inside the engine bay and formed in a frame shape having an opening disposed forward of the engine, and a grille shutter provided to the shroud and configured to open and close the opening. A front end of the upper lid part is placed on an upper side of the shroud, and the grille shutter is closed when an ignition is off.

A heat insulating cover (cylinder-head-side heat insulating cover ()) includes a top wall () and first side walls (). The top wall () covers a top surface of an engine () that is a surface of an upper portion of the engine (). The first side walls () cover respective upper portions of both side surfaces of the engine () 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 () vertically rotatably supporting the upper portion of the heat insulating cover including the top wall (). The upper portion of the heat insulating cover can be rotated, with the hinge mechanism () as a fulcrum, between a closed position where the engine () is shielded and an open position where the engine () is visible.
