Abstract: The present invention relates to a layout and a drive method of an in-wheel motor used for driving a vehicle. In a vehicle using a direct drive in-wheel motor, there is a problem that mechanical loss is caused by a load on an axle due to a weight of a vehicle body, a direction change during traveling, and the like. A stator of the direct drive in-wheel motor is eccentrically disposed in a half peripheral part on the front side of the vehicle body. A terminal of a stator that generates a rotational torque reaction conflicting with a load applied to an axle during traveling is preferentially activated. A mechanical loss of a direct drive in-wheel motor due to a load on an axle during traveling of a vehicle is reduced.

Abstract: [Technical Field] The present invention relates to a wheel deformation mechanism and a structure of a vehicular shock-absorbing device using the mechanism. [Technical Problem] In the conventional suspension device, there are problems that a vibration damping effect for an in-wheel motor vehicle is too low to alleviate an impact on the wheel and that a mounting space is required on the vehicle body side. There is a problem that since the conventional tire is poor in ability to absorb distortion of a contact patch caused by turning, the contact patch of the wheel is subjected to horizontal friction at the time of direction change. [Solution] An expansion and contraction mechanism as shown in FIG. 1 that connects two rotors and a band-shaped tread by a movable arm is incorporated in a wheel, [Main Use of Invention] The vehicle wheel is expanded and contracted by a rotation speed difference between the two rotors so as to control the posture of the vehicle body.

Abstract: A fuel injection device of a diesel engine capable of smoothly starting the diesel engine to match an environment around the engine by saving fuel, reducing the exhaustion of carbon dioxide, and suppressing black smoke in starting the diesel engine. A rack is operated by an actuator from a lowest rack position to a starting increased fuel amount position at a lower speed than that at which the rack is operated by the actuator from the lowest rack position to the starting increased fuel amount position at the maximum operating speed. The operating speed of the rack is set in two stages, and the later operating speed of the rack is reduced less than the operating speed of the rack up to a set intermediate rack target value P2. Then, the operating amount of the rack per hour is reduced after the ignition of the engine is recognized. Also, the operating speed of the rack is controlled according to an atmospheric temperature in starting the engine.

Abstract: A fuel injection device of a diesel engine capable of smoothly starting the diesel engine to match an environment around the engine by saving a fuel, reducing the exhaustion of carbon dioxide, and suppressing black smoke in starting the diesel engine. A rack (45) is operated by an actuator (41) from a lowest rack position to a starting increased fuel amount position at a lower speed than that at which the rack is operated by the actuator from the lowest rack position to the starting increased fuel amount position at the maximum operating speed. The operating speed of the rack (45) is set in two stages, and the later operating speed of the rack is reduced less than the operating speed of the rack up to a set intermediate rack target value P2. Then, the operating amount of the rack (45) per hour is reduced after the ignition of the engine (1) is recognized. Also, the operating speed of the rack (45) is controlled according to an atmospheric temperature in starting the engine.
