摘要:
An apparatus for controlling the exhaust timing of a two-cycle engine. A control valve is provided for adjusting the position of the top of the control port in the two-cycle engine as a function of the engine speed. A central processing unit receives a signal from an engine speed detector indicating the engine's operating speed. Based upon a control map, the central processing unit initiates action to adjust the position of the control valve.
摘要:
An exhaust timing controller for controlling an exhaust timing member in a two cycle engine including a control circuit for generating a control signal which actuates a mechanism for moving the exhaust timing member. The control circuit controls the member such that the member is drivable in a range from a fully open position to a fully closed position responsive to certain engine conditions including engine speed and rate of change of engine speed. A self cleaning cycle is provided which drives the exhaust timing member first to one position limit and then to the other.

Provided is a swing arm device for an electric two- or three-wheeled vehicle that can be reduced in the number of components for a reduction in weight while being mounted compact in an electric vehicle for which a swing arm of an electric vehicle includes a battery and a charger. The swing arm device for an electric two- or three-wheeled vehicle to be fitted on an electric vehicle includes a swing arm (30) one end of which is coupled to a swing shaft and the other end of which supports a rear wheel (WR), an electric motor (M) placed at the other end side of the swing arm (30) and for driving the rear wheel (WR), and a battery (56) for supplying electric power to the electric motor (M), and a charger (200) for charging the battery (56) is incorporated in the swing arm (30).

A battery is disposed close to a through-hole of a swing shaft that pivotally supports a swing arm on a vehicle body frame so as to be freely swingable at a position closer to the front of the vehicle body in the swing arm. An electric motor is disposed close to an axle of a rear wheel at a position closer to the rear of the vehicle body in the swing arm. The control board is disposed at a position outside of the battery in the vehicle width direction, and the heating element board is disposed at a position rearward of the vehicle body with respect to the control board and forward of the vehicle body with respect to the motor.

Inside of a swing arm (30) that pivotally supports a rear wheel (WR) of an electric two-wheeled vehicle (1) and that is freely swingably attached to a vehicle body, a battery (56), an electric motor (M) for driving the rear wheel (WR), and a board (50) serving as a control device for controlling the electric motor (M) are equipped. Coupling a throttle grip (80) and a throttle position sensor (60) by physical transmission means (62, 85, 86) therebetween allows a configuration so that a turning angle of the throttle grip (80) can be detected, and the throttle position sensor (60) is attached to the board (50). The board (50) is disposed with a planar portion oriented in a vehicle width direction.

A power generation control device for a generator driven by a four-stroke cycle engine is provided. The power generation control device includes a switching circuit for controlling an output current from the generator; and a power generation period control device configured to operate the switching circuit to output the output current from the generator in only a predetermined power generation period of the four strokes of the engine, wherein the power generation period ranges from an expansion stroke to an intake stroke of the four strokes.

An apparatus for determining whether polygons which form objects defined by graphic data generated by CAD intersect with virtually generated light rays. Polygons which are not intersected are removed from the graphic data as unnecessary for the generation of CG data. An apparatus is also described in which path passage points which pass through an animation path within a virtual world are interactively set. If an object exists that interferes with a path that joins adjacent path passage points, an alternate route path which detours around the interfering object is generated. An apparatus is also described in which a path of a moving object is interactively set on a perspective view of the virtual world as viewed from one direction. The position of the set path in the virtual world is calculated, and the position of the path in the direction of viewing is corrected to a position that is removed from an object by a prescribed distance.

A battery module mounting structure includes a housing structure housing a battery supplying electric power to the electric motor of a motor-driven two-wheeled vehicle and a PDU controlling the electric motor. The housing case is configured to be mountable to and dismountable from the swing arm with the electric motor and a control substrate housed in the housing case. The swing arm is formed as a cantilever type in which an arm portion disposed on the vehicle-widthwise right or left of a rear wheel supports the rear wheel. The battery shaped in a rectangular parallelepiped is housed in the housing case with a longitudinal direction thereof facing in a vehicle-width direction. The housing case is mounted from a vehicle-widthwise inside on a lateral surface of a swing arm housing at a position vehicle-body-forward of the rear wheel and vehicle-body-rearward of a through-hole, the swing arm housing supporting the arm portion.

A battery configured as a plurality of battery cells for an electric vehicle with one board for supplying electric power to an electric motor. Each battery cell is provided with positive and negative electrodes on the side of the board. The board is provided with a plurality of cell connecting parts for transmitting cell information of each battery cell corresponding to each electrode. Sensor wiring connects each electrode and each cell connecting part. Wiring is formed are arranged over the board that radiates heat via an insulating adhesive. A heating element is mounted on a first heat-conduction member formed on a top face of the uppermost wiring board. A second heat-conduction member is formed on the downside of the lowermost wiring board. The first heat-conduction member and the second heat-conduction member are touched via a third heat-conduction member arranged in a through hole bored through each wiring board.
