摘要:
A scooter type vehicle comprises: a unit swing type engine provided with an engine body having a cylinder assembly forward inclined in a horizontal direction and having a central axis arranged along a longitudinal direction of a vehicle body and a transmission case rearward extending from one side of the engine body and supporting a rear wheel to a rear end thereof, swingably pivoted to a vehicle body frame and flexibly supported to a vehicle body frame through a cushion unit; a fuel injection type intake apparatus comprising a throttle body connected to an intake port of the cylinder assembly, an air cleaner connected to the throttle body, fuel injecting means and a controller for controlling a fuel injection amount; and an article accommodation box arranged above the unit swing type engine. In such scooter type vehicle, a bottom surface of the accommodation box (7) is formed in an obliquely forward descending manner so as to be substantially parallel to a line (X-X, X'-X') connecting the highest position of the unit swing type engine (10) in a state that the cushion unit (15) is most compressed and the highest position of the fuel injecting means (50) or the air cleaner (48), and the controller (58) is arranged in adjacent to a fuel tank (9) arranged in the longitudinal direction of the vehicle body in the accommodation box (7).

摘要:
A scooter type vehicle such as motorcycle has a structure in which a seat member is arranged above a rear wheel so as to extend in a longitudinal direction along an advancing direction of the vehicle, the seat member includes a drive's seat section and a pillion section divided along the longitudinal direction of the vehicle body, the pillion section having a seat surface higher in level than that of the rider's seat section, and an article accommodation box is disposed below the seat member. The article accommodation box 18 is disposed substantially directly above the rear wheel 15 and below the pillion section 19b and has an inner volume sufficient to accommodate two helmets 16, 17 in a manner aligning with each other along the longitudinal direction of the vehicle body.

摘要:
An intake apparatus of an internal combustion engine for a vehicle comprises a duct for taking into a wind during a running of a vehicle, an air cleaner operatively connected to the duct, a fuel supply device for injecting a fuel into an intake air coming from the air cleaner, a movable valve arranged between an outlet port of the duct and an inlet port of the air cleaner, a negative-pressure motor for driving the movable valve, and an electronic control unit for controlling the movable valve. The electronic control unit is connected to an ignition means, and the electronic control unit controls the opening and closing of the movable valve in accordance with a rotational speed of an internal combustion engine, an opening degree of a throttle of the engine and a gear position of the engine as control parameters and carries out a delay angular control of an ignition timing in response to the opening and closing control of the movable valve.
