Abstract: An intake system for an engine includes an intake manifold having a surge tank room and branch passages, and a water-cooling type cooler having a first cooling unit and second cooling units. The surge tank room is disposed on a downstream side of a supercharger in a flow direction of intake air. Supercharged intake air flowing into the surge tank room is distributed among intake ports respectively through the branch passages. The first cooling unit is inserted in the surge tank room, and cools supercharged intake air which has flowed into the intake manifold through heat exchange between supercharged intake air and coolant flowing in the first cooling unit. The second cooling units are inserted respectively in the intake ports, and cool internal EGR gas, which has been recirculated into their corresponding intake ports, through heat exchange between internal EGR gas and coolant flowing in the second cooling units.

Abstract: An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The pedal lever operates according to a step-on operation. The lock mechanism can restrict the operation of the pedal lever. The actuator switches between a locked state in which the operation of the pedal lever is restricted by the lock mechanism and an unlocked state in which the operation of the pedal lever is not restricted. The ECU include a lock operation determination unit and an actuator control unit. The lock operation determination unit determines switching of the lock/unlock operation by the lock mechanism, in response to a voice instruction of a driver. The actuator control unit controls a drive of the actuator according to a determination result of the lock operation determination unit.

Abstract: A cooling water control valve device includes a housing and a valve. The housing includes an inside space, an attachment surface, at least one inlet port, and at least one outlet port. The attachment surface is in contact with an outer wall of the engine. The valve is disposed in the inside space to control communication between the at least one inlet port and the at least one outlet port by rotating. The housing includes a housing body that defines the inside space therein and a bypass passage forming member that defines at least a portion of a bypass passage. The bypass passage bypasses the valve and fluidly connects the at least one inlet port and the inside space. The housing is attached to the engine such that the attachment surface comes into contact with the outer wall of the engine.
