  • Publication number: 20230065963
    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.

  • Patent number: 9163554
    Abstract: A case is connected between an outlet side of a turbocharger and an intake port of an engine. A cooling passage and a bypass passage are partitioned in the case to split intake air into two flows. A storage unit is formed in a bottom portion of the case to accumulate liquid. The cooling passage is located along a gravity direction to flow intake air from a lower side to an upper side. The bypass passage flows intake air to bypass the cooling passage. A valve controls opening of the cooling passage and the bypass passage on an inlet side or on an outlet side. The valve opens the bypass passage to forcedly supply at least a part of intake air, which is drawn into the case, through the storage unit and the bypass passage into the intake port.

  • Patent number: 9032914
    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.

  • Patent number: 8459224
    Abstract: An intake manifold is located on a downstream side of a throttle valve in an intake passage. A switching valve is placed on an upstream side of a connection between a communication conduit and an outlet of a lower portion of a surge tank of the intake manifold and is adapted to open or close the communication conduit. A control device controls the switching valve to open or close the switching valve. The control device closes the switching valve when an operational state of an engine is in one of idling time, accelerating driving time and high speed driving time of a vehicle, and the control device opens the switching valve when the operational state of the internal combustion engine is in decelerating driving time of the vehicle.

  • Patent number: 7219652
    Abstract: A bearing support device includes a rotor, a bearing member, and a bearing holding member. The rotor rotates about a rotation center axis. The bearing member rotatably supports the rotor within a bearing hole passing through the bearing member. The bearing holding member holds the bearing member in a secure manner within a fitting hole that passes through the bearing holding member along the center axis of the rotor via an engagement force produced by tightly fitting the bearing member. The rotor and bearing member are made of a resin. An engagement section is provided for tightly fitting the bearing member into the fitting hole relative to the bearing hole to enable an engagement force produced by the tight fitting to act in a direction that does not affect an inner diameter dimension of the bearing hole.
