The present teaching provides a straddled vehicle including a compact and lightweight high-voltage hybrid system. The straddled vehicle includes an engine, a drive wheel, a high-voltage power supply system, a first permanent magnet motor generator, a first MG control unit, and a first power transfer device electrically connected to the high-voltage power supply system without a secondary battery that is electrically connected to the high-voltage power supply system and functions at a high voltage. The first MG control unit uses, as power, the high voltage that is higher than a low voltage of a low-voltage battery to perform a field-weakening control on the first permanent magnet motor generator, which includes a rotor that rotates at the same speed as the engine of the straddled vehicle and in which the number of magnetic poles is greater than 2/3 the number of teeth, so that the level of voltage suppression that is achieved through the field-weakening control increases because of increased reactance resulting from a greater number of magnetic poles of the first permanent magnet motor generator, and so that a component of current for the field-weakening control is supplied to a winding by overcoming increased reactance at high rotation speeds of the engine of the straddled vehicle because of the field-weakening control using the high voltage as power.

(ii) On the first cross section CS, at least part of the EGR cooler 51 is directly above a protrusion 63 or a protrusion 64 of the engine 10, which covers at least part of a generator 61 or a clutch 62. (iii) On the first cross section CS, between a right surface 51b or a left surface 5 la of the EGR cooler 51 and part of the left surface 10b or the right surface 10a of the engine 10, a gap 71 or a gap 73 allowing an airflow to pass through is provided, and/or, between a bottom surface 51d of the EGR cooler 51 and the protrusion 63 or the protrusion 64, a gap 72 or a gap 74 is provided to allow an airflow to pass through. The first cross section CS is parallel to the central axial line Cy of a cylinder hole 15, parallel to or oblique to a vehicle up-down direction, and parallel to a vehicle left-right direction.

There is disclosed a fuel adjustment device, including an ECU (10) and a catalyst (53) downstream oxygen sensor (SE4); ECU (10) controlling a fuel injection device (61) that causes an engine (5) to work; the catalyst downstream oxygen sensor (SE4) being provided downstream of a three-way catalyst (53) in an exhaust system attached to engine (5) and detects an oxygen concentration of an exhaust gas; ECU (10) adjusting a fuel supply amount such that an engine rotation speed decreases when the engine rotation speed reaches a first rotation speed (rs1); the first rotation speed (ra1) being the rotation speed corresponding to overspeeding; when the engine rotation speed decreases and reaches a second rotation speed (rs2), an amount of fuel being supplied to engine (5) is changed back to a normal amount; thereafter, when the engine rotation speed is continuously maintained in a monitoring range, the fuel supply amount being adjusted based on a detection result of the catalyst downstream oxygen sensor (SE4); the monitoring range is a range that includes the second rotation speed (rs2) and is lower than the first rotation speed (rs1).

In a vehicle side view, an electrically assisted turbocharger controller (34) or an electrically assisted turbocharger (32) of a leaning vehicle (1) is provided forward of a front end face (11f) of a cylinder member (11) in a vehicle front-rear direction so as to at least partially face the front end face (11f), and a motor generator controller (22) or the electrically assisted turbocharger controller (34) is provided rearward of a rear end face (11r) of the cylinder member (11) in the vehicle front-rear direction so as to at least partially face the rear end face (11r). A part (42) of an electrically assisted turbocharger high voltage harness (40), which connects the electrically assisted turbocharger controller (34) and the motor generator controller (22) or a part (41), which connects the electrically assisted turbocharger (31) and the electrically assisted turbocharger controller (34) is at least partially provided in a space that is (i) above the lowermost end of a crankcase member (12) in a vehicle up-down direction, (ii) below the uppermost end of the cylinder member (11) in the vehicle up-down direction, (iii) inside the maximum width of the crankcase member (12) in the vehicle left-right direction, and (iv) outside the cylinder member (11) in the vehicle left-right direction.

It is intended to provide a watercraft positional information managing system, whereby GPS-based positional information can be inhibited from being falsified. The present watercraft positional information managing system includes a server and a watercraft. The watercraft includes a propulsion device and a communication device performing communication with the server. The communication device includes a position detecting section detecting positional information of the watercraft. The propulsion device includes an engine and a controller controlling the engine. The controller is connected to the communication device. The controller outputs data related to the engine to the communication device. The communication device transmits the data related to the engine inputted thereto and the positional information of the watercraft to the server. The server receives the data related to the engine and the positional information of the watercraft and determines whether or not the positional information of the watercraft is genuine based on the data related to the engine.
