  • Patent number: 10247083
    Abstract: A straddle vehicle is capable of discharging high-temperature outdoor air having passed through a radiator with high efficiency. A motorcycle 1 includes a radiator, a fan, and a fan shroud. The radiator lowers the temperature of a coolant by heat exchange between outdoor air and the coolant. The fan suctions outdoor air, to make the outdoor air hit the radiator arranged upstream in an outdoor air flow direction. The fan shroud covers at least part of the fan, and discharges high-temperature outdoor air, which is outdoor air suctioned by the fan and having passed through the radiator, to outside. The fan shroud has a discharge opening and an air guide. The discharge opening allows the high-temperature outdoor air to be discharged outside. The air guide guides the high-temperature outdoor air such that it is discharged through the discharge opening in a direction including a laterally outward component.

  • Patent number: 9297292
    Abstract: An engine cooling device including a water pump, a radiator, an exhaust heat recovery unit, and a coolant circulation circuit for circulating a coolant in these apparatuses includes a flow rate limiting means that limits the flow rate of the coolant that circulates in the exhaust heat recovery unit in the case where a temperature of a sensor element of an A/F sensor, that is disposed downstream of the exhaust heat recovery unit in an exhaust path, is below a preset activation temperature. An extent of opening of a second switching valve is made smaller in the case where the temperature of the sensor element is below the activation temperature than in the case where the temperature is equal to or higher than the activation temperature.

  • Patent number: 9145821
    Abstract: An engine having a multi flow rate control valve may include a valve, a valve housing and a driving unit. The valve may have a hollow pipe structure and coolant holes through which a coolant supplied to a space at a center portion of the valve is to be distributed and cooled outside of the valve. The valve housing may be coupled with the valve such that an inner side of the valve housing is capable of being in close contact with an outer side of the valve, and have coolant outlets formed at positions corresponding to the coolant holes. The driving unit may rotate the valve to selectively connect the respective coolant holes to the corresponding coolant outlets or close the coolant holes by bringing them in close contact with the inner side of the valve housing.

  • 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.
