    • An internal combustion engine having a combustion cylinder, a piston moving within the cylinder, an intake manifold through which air flows into the cylinder, a fuel control for controlling the flow of fuel into the cylinder, and an inlet valve arrangement for controlling the flow of air into the cylinder, and in which there is an improvement in the inlet valve arrangement which comprises an elongate thin wall right circular cylindrical valve member mounted for rotation within the intake manifold about the longitudinal axis of the valve member and having an inlet flow opening therethrough extending lengthwise of said member for a predetermined length and arcuately thereabout over an arc of at least about 100 degrees and an air flow guide stationarily mounted within the valve member for directing air flow into the cylinder and for establishing the cross sectional area of a flow passageway for such air flow.

    • An apparatus and method by which possibly destructive stress of torsional vibration in a rotating crankshaft/flywheel system of a multicylinder internal combustion engine is avoided by effectively isolating the flywheel from the crankshaft for torsional vibration considerations. The flywheel and crankshaft are coupled by a resilient coupling which accommodates angular movement between the components and which has a torsional spring rate which is relatively low compared to the torsional spring rate of a conventional crankshaft/flywheel system. The coupling reduces the natural frequency of torsional vibration of the system to a frequency well below the normal operating range of the engine in terms of revolutions per minute, thereby substantially eliminating the effects of torsional vibration in the normal operating range of the engine.
    • 通过有效地将飞轮与曲轴隔离以用于扭转振动考虑,可以避免多缸内燃机的旋转曲轴/飞轮系统中的扭转振动的破坏性应力的装置和方法。 飞轮和曲轴通过弹性联轴器联接,弹性联轴器容纳部件之间的角运动,其扭转弹簧速率与常规曲轴/飞轮系统的扭转弹簧速率相比相对较低。 联轴器将系统的扭转振动的固有频率降低到远低于发动机的正常工作范围的频率(以每分钟转数),从而基本上消除了发动机正常工作范围内的扭转振动的影响。
