摘要： A method for automatically controlling an internal combustion engine, in which an axial displacement (s(t)) and an angle of rotation (w(t)) of a gas-exchange valve are measured during a valve stroke. A displacement deviation is computed from the displacement (s(t)) relative to a reference valve, and an angle of rotation deviation is computed from an initial value and an end value of the angle or rotation. The further operation of the internal combustion engine is set on the basis of the displacement deviation and the angle of rotation deviation.

摘要： With vertical movement of a valve in an engine, a suspending member which suspends from a retainer engaged in the valve goes up and down with respect to a standing member on a cylinder head. A projection provided on the suspending member slides on inclined guide surfaces of the standing member, thereby attaining relative rotation of the suspending member forcibly with respect to the standing member, so that the valve is rotated on its axis.

摘要： Disclosed is a valve gear for use in a four-cycle engine which eliminates the necessity of providing a cam shaft. In the valve gear, a guide or guides, each of which is shaped like a closed curve making two rounds of a crank shaft with one intersection on the way, are provided. An air-intake valve and/or exhaust valve are controlled in accordance with the movement of a slider member sliding along the guide or guides.

摘要： A valve is reciprocable between opened and closed positions along a longitudinal axis and is rotatable about the axis by a rotator mechanism. The rotator mechanism includes first and second parts movable axially and rotatably relative to one another along and about the longitudinal axis. A plurality of shiftable ball elements are located between the first and second parts and are movable along predetermined paths for imparting relative rotation between the parts during relative axial movement therebetween. Each ball is constrained for movement along its predetermined path by surfaces which define a pocket in one member and in which the ball is located. Each of the pockets have a ramp along which the ball moves upon relative axial movement of the parts. A spring biases the ball to one end of the ramp and the ball moves toward the other end of the ramp when the first and second parts move axially towards each other. The ramp is defined by a plurality of surface portions which extend at different angles to a plane extending perpendicular to the longitudinal axis. The surface portion adjacent the one end of the ramp to which the ball is biased extends at the greatest angle to the plane and the angle at which the other surface portions extend to the plane are progressively less as the ramp progresses toward the other end of the pocket.
