To provide a motorcycle in which a distinction between a main harness and ABS pipes can be easily made to enhance flexibility of packaging design of the motorcycle and to facilitate operations for assembly and piping, thereby improving productivity of the motorcycle. A main harnessfor supplying electric power from a batteryto multiple electric componentstois arranged on one side in a right-to-left direction of a vehicle, and ABS pipesandfor transmitting a hydraulic pressure to a brake caliperare arranged on the other side in the right-to-left direction of the vehicle

Motorcycle

A motorcycle wherein an attachment angle of a tail light bulb is increased to reduce a distance between a seat and a tail light unit, to improve the flexibility of a short tail design around a tail light of a motorcycle. The motorcycle includes a rear cowl attached to a rear part of a vehicle body frame, a seat catch arranged on a rear end portion of the vehicle body frame and configured to lock and to unlock an openable/closable seat, a tail light unit arranged behind the seat catch and attached to the rear cowl, a tail light bulb attached to the tail light unit in a forward-tilted state, and a rear fender covering an upper part of a rear wheel WR. An opening that allows access to the tail light bulb is formed at a portion of the rear fender facing the tail light bulb.

In a charging system, an interlock switch is configured to be turned on when a power switch of a vehicle body is turned off and turned off when the power switch is turned on is disposed between a negative terminal of a battery and a second negative input portion. A first positive output portion and a second positive output portion are connected to each other with a coil of a relay circuit installed in the charger body interposed therebetween. A relay switch of the relay circuit in which on and off operations are switched by the coil is connected to the first positive output portion.

Charging system

An electronic control device is provided for an aviation engine. Each cylinder of the engine is equipped with main ignition plugs and back-up ignition plugs. Lane A including a first CPU and lane B including a second CPU are included in an ECU. The ignition control system is multiplexed by the two lanes A, B. The first and second CPU independently calculate ignition timing for each cylinder based on each sensor signal, and then exchange the results of these calculations with each other. At each cylinder, ignition timing is synchronized in such a manner that ignition timing of the main ignition plugs and ignition timing of the back-up ignition plugs match. The electronic control device so configured has a high level of redundancy with a small number of CPU's. Thus, electronic control device can be provided for the aviation engine with few limitations placed in relation to installation location.

A shield cover for an engine is provided to shield electric parts, in an engine wherein an engine body includes a crankcase having a plurality of cylinder bores. An intake chamber common to all of the cylinder bores is spaced away from the crankcase. The shield cover is made in one piece, making it possible to reduce the number of parts and also of the cost, and to achieve a generally compact configuration of the engine. A plurality of electric partsL,R,L,R,are disposed around an intake plenum, and the plural electric partsL,R,L,R,are covered with a shield coverattached to the engine bodyin such a manner as to cover at least part of the intake plenum

Engine including electrical interference shield

A fuel supply port portion incorporates tank fittings such as a fuel pump and a residual fuel meter unit integrally therein as a tank fittings assembly. The fuel supply port portion is formed as a separate body from a tank body of a fuel tank and is removably attached to the tank body. The structure of the tank body can be simplified, and in the case where the tank body is made of a resin, it is not necessary to perform an insert molding operation. Consequently, it is possible to fabricate the tank body easily and also possible to thin the tank body, thereby ensuring a sufficient capacity of the fuel tank. Further, since tank fittings mounting portions are concentrated in the fuel supply port portion, it is possible to assemble the fuel tank in an efficient manner.
