    摘要: An improved head assembly replacement for the Harley Davidson Motorcycle engine 20 adapted to utilize four valves per cylinder using push rods 50 without modification to the engine block, and maintaining the existing location and configuration for the mounting of the normal intake and exhaust systems. The standard rocker arms actuate the new dual intake and exhaust valves through a yoke 54 bridging each pair of valves. The exhaust valve and intake valve pairs are inclined at an included angle of 50 to 70 degrees in the plane of the engine crankshaft. The pushrods 50 remain in the standard position and the self-adjusting hydraulic tappets are retained.

    摘要: A valve train for internal combustion engines utilizing an inverted bucket tappet with a pivot structure operatively disposed between the tappet and the end of the valve stem allowing the valves to be angulated with respect to each other and to the axis of the cylinder in both the transversal and the horizontal planes of the engine. Accordingly on a multi-valve engine, the valves extend radially from the associated combustion chamber to open and increase space in the center of the cylinder head for spark plugs, injectors, or pre-combustion chambers and so that the combustion chamber can be designed with a hemispherical surface, with tangentially disposed valve heads. The construction allows the use of large valves in conjunction with stronger, better-cooled valve seats and bridges. The tappets can be actuated conventionally by direct-acting overhead camshafts, or by rocker arms and "T" bridges.

    摘要: A valve operating device for internal combustion engine which includes a cam shaft rotated by a crankshaft and a rocker arm which follows the cam of the cam shaft to open and close an intake or exhaust valve of the engine. Oil-pressure-operated control is provided for suspending the operation of the intake or exhaust valve according to the operating conditions of the engine. For this purpose, a cam shaft passage is formed in an oil pressure supplying passage which extends from an oil pressure source through an oil passage in the rocker shaft to the control mechanism in such a manner that the cam shaft passage extends through one end portion of the cam shaft. A changeover valve for opening and closing the cam shaft passage is provided at the one end portion of the cam shaft. A centrifugal governor provided at the one end portion of the cam shaft rotates with the cam shaft and turns the changeover valve when the speed of the cam shaft is in a predetermined range, thereby to communicate the oil pressure source with the control mechanism.

    摘要: A control system for an engine having a first cylinder and a second cylinder is disclosed having a first engine valve movable to regulate a fluid flow of the first cylinder and a first actuator associated with the first engine valve. The control system also has a second engine valve movable to regulate a fluid flow of the second cylinder and a sensor configured to generate a signal indicative of a pressure within the first cylinder. The control system also has a controller that is in communication with the first actuator and the sensor. The controller is configured to compare the pressure within the first cylinder with a desired pressure and selectively regulate the first actuator to adjust a timing of the first engine valve independently of the timing of the second engine valve based on the comparison.

    摘要: A device for controlling the valves of an internal combustion engine having overhead valves comprises a control cam, and two oscillating rockers for each valve. The free end of each rocker is disposed between the cam and the end of the valve stem. The free end of the rocker in contact with the cam has a roller which is in rolling contact with the cam. The lower planar surface of this rocker is in contact with the spherical head portion at the free end of the other rocker. This spherical free end is in in turn in contact with the end or tappet of the valve stem. The rocker in contact with the end of the valve stem oscillates in a plane perpendicular to the axis of the valve. The rocker in contact with the cam oscillates about an axis parallel to the axis of the camshaft. The mid-point of the path of contact between the spherical head portion and the end of the valve stem is disposed substantially along the axis of the valve.
