摘要： A straddled vehicle includes a radiator arranged forward relative to an internal combustion engine and an ECU arranged sideward of the internal combustion engine. At least a portion of a tubular air passage through which the air for cooling the ECU passes is formed between a support cover supporting the ECU and an outer cover. A front cover, an upper cover and an under cover form a groove portion, which extends rearward from a front end portion located upward and forward relative to the radiator and is recessed inward in the vehicle width direction. An inlet opening that communicates with the air passage is formed in the groove portion.

摘要： A throttle device, comprising: a throttle valve (13) disposed in a plurality of intake passages (12) of a throttle body (11); a throttle shaft (14) supporting the throttle valve (13); a motor (15) for driving the throttle valve (13) to open and close through the throttle shaft (14); a rotation transmission mechanism (20) interposed between the motor (15) and the throttle shaft (14); and a position sensor to detect a displacement in the rotation transmission mechanism (20). The rotation transmission mechanism (20) includes a pinion (21) driven by the motor (15) and a control gear (23) interlocked with the pinion (21) and integrally connected to the throttle shaft (14). The position sensor (30) to detect an angular displacement of the control gear (23) and the rotation transmission mechanism (20) are disposed between the plurality of intake passages 12.

摘要： In an engine, a cylinder block and a cylinder head are connected with a crankcase in a forwardly inclined posture. A dual clutch connects or disconnects a transmission path of power of the engine to a transmission. An actuator chamber houses an actuator that controls a hydraulic pressure of the dual clutch. The actuator chamber is disposed on an upper surface of the cylinder block at a position posterior to the cylinder head and anterior to the crankcase in a vehicle longitudinal direction.

摘要： An engine for a two-wheeled vehicle includes at least one cylinder comprising a combustion chamber and a cylinder head positioned adjacent the combustion chamber. The engine further includes a crankcase coupled to the at least one cylinder which includes a crankshaft. Additionally, the engine includes a valve train operably coupled to the crankshaft which includes at least one intake valve fluidly coupled to the combustion chamber, at least one exhaust valve fluidly coupled to the combustion chamber, at least one pushrod operably coupled to at least one of the intake valve and the exhaust valve, at least one camshaft operably coupled to the at least one pushrod and the crankshaft, and a cam phaser assembly operably coupled to the at least one camshaft and positioned generally outside an envelope of the cylinder head.

摘要： An engine includes: a cylinder head that forms an intake port connected to a combustion chamber; a throttle body that is joined to the intake port and adjusts a degree of an opening of an intake passage by rotating a throttle vale around a rotation axis of a valve shaft, the throttle vale being fixed to the valve shaft; and a case that stores a drive member and supports a drive motor, the drive member being fixed to the valve shaft, the drive motor generating a drive force that is transmitted to the drive member. The case overlaps with the intake port as seen in a side view. Accordingly, in the engine, it is possible to reduce the volume of the intake passage between the throttle valve and the combustion chamber.

摘要： A canister includes a fresh air introducing port for introducing a fresh air into the canister. The fresh air introducing port is opened in a space formed by at least a tank cover. The canister is connected to a drain pipe for draining a liquid in the canister to the outside of the canister. The drain pipe extends rearward at a height same as or higher than a lower end of the tank cover. The drain pipe merges with a supplied-fuel drain pipe and extends to a lower portion of a vehicle. The supplied-fuel drain pipe drains a fuel around a fuel supply port of a fuel tank.

摘要： An internal combustion engine includes a crankshaft that has a journal linked to a bearing and is rotatably supported on the crankcase, a power transmission gear fixed to an extremity of the crankshaft that has a smaller diameter than a diameter of the journal and projects outward of the crankcase, a to-be-detected body that is fixed on an outer periphery of a collar member disposed between the bearing and the power transmission gear and is relatively non-rotatably supported on the crankshaft, and a detection sensor that is made to face a trajectory of the to-be-detected body and detects movement of the to-be-detected body to generate a pulse signal. This provides a structure for disposing a to-be-detected body that enables any increase in the dimensions of an internal combustion engine to be avoided.

摘要： A motorcycle includes a first gear provided on a crankshaft, a second gear provided on a second clutch member of a clutch that meshes with the first gear, a starter motor located above the crankcase and rearward of the cylinder body, and a link gear that links together the second gear and the starter motor. The starter motor is located above a transmission. The starter motor includes an overlapping portion that overlaps with the clutch, as the vehicle is seen from the side, and a front portion located forward of a center axis of a main shaft, as the vehicle is seen from the side.
