摘要:
A hybrid vehicle in which an electric motor is disposed in the vicinity of a center of a vehicle body to reduce lateral expansion. The hybrid vehicle includes an engine, a motor, and a power transmission mechanism for transmitting power of the engine and the motor to a rear wheel. The engine is suspended on the vehicle body in a non-swingable manner with a cylinder extending in a substantially horizontal direction and a crankshaft provided to be oriented in a vehicle width direction. The electric motor is located in front of and above the crankshaft of the engine.
摘要:
A technique for enabling reduction of fuel consumption without greatly changing an engine structure and without impairing a feeling of operation of a vehicle as a motorcycle. An engine includes a crankshaft and a primary gear integrated with the crankshaft that is attached such that the power of the engine is transmitted to a wheel. A one-way clutch transmits the power from the crankshaft to the primary gear but does not transmit the power from the primary gear to the crankshaft. The one-way clutch is provided between the crankshaft and the primary gear with a regenerative brake motor being provided on the primary gear. The engine is non-swingable mounted on the vehicle body with a cylinder extending in a substantially horizontal direction and a crankshaft provided to be oriented in a vehicle width direction. An electric motor is located in front of and above the crankshaft of the engine.

A hybrid motorcycle includes a body frame, a front wheel, and a hybrid driving source. The hybrid driving source is mounted on the body frame between a head pipe and a swing arm pivot. The hybrid driving source includes an engine and a motor. The engine has a crankshaft whose axial direction is substantially parallel to a vehicle longitudinal direction. The motor is provided at a front shaft end adjacent to the front wheel.

A variable compression ratio engine includes a control actuator which has a simple structure, seals well internally, and provides high reliability. In the variable compression ratio engine, a connecting rod is divided into at least two portions. A control rod is operatively connected to a juncture of the connecting rod. A support shaft position of the control rod is displaced. The control rod is operatively connected to a right cylinder rod of a piston-type double-acting hydraulic control cylinder. A piston section of the hydraulic control cylinder is configured to selectively move in accordance with displacement of the support shaft position of the control rod. A channel is used to connect two hydraulic chambers divided by the piston section. The channel is configured to selectively control the flow of hydraulic fluid from the right hydraulic chamber to the left hydraulic chamber, and vice versa.

A hybrid vehicle includes an engine, a motor, a multi-stage gear transmission, and an actuator. The engine has a crankshaft, a crankcase, and a cylinder. The motor is provided on the crankshaft. Through the multi-stage gear transmission, an output of the crankshaft is changed to be used for traveling of the vehicle. The actuator is configured to automatically shift the multi-stage gear transmission and is provided in the crankcase in proximity to the motor. A radius from a center line of the cylinder to a part of the actuator farthest from the center line is shorter than a radius from the center line to a part of the motor farthest from the center line. The actuator has a width less than a width of the motor in a direction perpendicular to the crankshaft.

In order to do away with the need for a power source switching operation, and to improve motor regeneration charge efficiency in a hybrid vehicle, a one-way clutch is provided between an internal combustion engine and an electric drive motor.

A valve operating device for an internal combustion engine is capable of increasing a negative valve overlapping duration when maximum lift amounts of an intake valve and an exhaust valve are small. The valve operating device is provided with intake-side and exhaust-side characteristic adjustment mechanisms for adjusting operating characteristics of an intake valve and an exhaust valve. Each characteristic adjustment mechanism has a control cam rotating integrally with a cam shaft, an electric motor that causes a holder pivoted on the cam shaft to rotate about the cam shaft, a sub-rocker lever pivoted on the holder and caused to oscillate by the control cam, and a valve cam that is caused to oscillate around the cam shaft by oscillation of the holder and the sub-rocker lever, for causing oscillation of main rocker levers. The electric motor causes the holder to oscillate in such a manner that the valve open timing of the intake valve is retarded as a maximum lift amount of the intake valve becomes smaller and the valve close timing of the exhaust valve is advanced as a maximum lift amount of the exhaust valve becomes smaller.
