    Abstract: The use of devices to simultaneously actuate multiple valves operatively associated with a common combustion chamber is becoming more important due to the increase in multiple valve internal combustion engines. The ability to simultaneously actuate multiple valves reduces weight, costs, and parts in the engine. The subject valve actuation device (10) has a valve arrangement (12) with at least three valves (14, 15, and 16) having stem portions (40, 41, and 42) operatively associated with a common combustion chamber (22). A free-floating bridge (62) having three recesses (64, 65, and 66) is seated on the stem portions (40, 41, and 42). A movable rocker arm (34) having two fingers (36 and 37) contacts the free-floating bridge (62) at locations sufficient to actuate the valves (14, 15 and 16) simultaneously.

    Abstract: Several embodiments of internal combustion engines having at least five valves, three intake and two exhaust, all operated by a single camshaft. The intake valves are disposed so as to provide a smooth combustion chamber configuration by minimizing the difference in-angle between the valves and the valves and rocker arms are arranged so that different degree of lift may be provided. All of the intake valves have the same stem length. One rocker arm operates one valve and another rocker arm operates two valves with the two valves being operated being differently configured so as to provide the desired different lift. In addition, a staged intake system is included that has a single intake passage that extends perpendicular to a plane containing the cylinder bore axis and serving one intake valve and a siamese intake passage serving the other intake valves. The siamese intake passage has a section that extends also perpendicularly to the plane.

    Abstract: Intake ports are arranged independently from each other between an injector and each combustion chamber and are formed in an inverted triangular cross-sectional shape, whereby intake fluids flow along upper walls of the corresponding ports and become a stratified tumble flow in the combustion chamber 10. One of the three ports, said one port being centrally located and opposing a spark plug, is used as an air-fuel intake port, while the remaining ports arranged on both sides of the port are employed as air intake ports. A fuel injector is provided to feed fuel only to the port. An air-fuel mixture drawn into the combustion chamber through the port flows as a tumble flow. This tumble flow is flanked by tumble flows of air drawn into the combustion chamber through the ports respectively, whereby tumble flows flow in the form of a three-layer tumble swirl as a whole.

    Abstract: A rocker arm and valve arrangement for a multiple valve internal combustion engine that permits a low engine height even though two of the valves reciprocate along axes that are not parallel to each other. However, the configuration is such that the loading on the valve actuating mechanism and specifically the followers and tips of the valves is minimize and so that wear on the tips of the valves is equalized.

    Abstract: A timing system, in particular for high performance internal combustion engines, having five or more valves per cylinder, is described. Three identical valves serving a given cylinder of an engine are controlled by a single camshaft by means of a pair of corresponding cams which act together with a pair of tappets which are mounted slidably in corresponding guides in the cylinder head. The tappets act together at the edges with corresponding valve stems of the three valves which are slidably mounted within second guides within the cylinder head, against the force of corresponding elastic means in a radially eccentric position with respect to the axis of the tappets in such a way that the valve stem of the intermediate valve acts simultaneously with both tappets, while the valve stems of the two lateral valves each act together with a corresponding different tappet in positions of mirror-image symmetry with respect to the center plane of the cylinder passing through the axis of the intermediate valve.

    Abstract: An intake system, for use with an internal combustion engine having a plurality of intake valves for each cylinder, includes a plurality of intake ports, opening into the combustion chamber side of the internal combustion engine at different distances from a spark plug of the cylinder. The intake valves are controlled to keep an intake port located at the shortest distance from the spark plug opened only slightly in an early intake cycle stage while opening the other intake ports at their desired timings. The intake port located at the shortest distance from the spark plug is subsequently opened at a desired timing, thereby aspirating a substantial quantity of air through the closest intake port at a later time than through the other intake ports.

    Abstract: An intake system having first, second and third intake ports connected to first, second and third air intake passages, respectively and up stream ends of three air intake passages are connected to a common air intake passage. The first air intake passage is set to supply air through the first intake port along an inner peripheral surface of the combustion chamber. The second and third air intake passages are set so that axial center lines thereof may intersect an axial center line of the first air intake passage and an intersecting point of the axial center lines of the third and first air intake passages are up stream of the intersection of the axial center lines of the second and first air intake passages. Thus, swirl of intake air in the combustion chamber from the third intake port is stronger than that generated by the intake air from the second intake port. Then, swirl around an ignition plug arranged almost in the center of the combustion chamber is strengthened. In addition, turbulent flow of intake air is generated by using the difference of velocities between the outside swirl and the swirl around the spark plug, resulting in improved combustability. In addition, cooling loss of the cylinder is prevented by relatively reducing the swirl around the outer periphery of the combustion chamber.

    Abstract translation: 具有分别连接到第一，第二和第三进气通道的第一，第二和第三进气口和三个进气通道的上游端的进气系统连接到公共进气通道。 第一进气通道设置成沿着燃烧室的内周面通过第一进气口供给空气。 第二进气通道和第三进气通道的轴线中心线可以与第一进气通道的轴线中心线相交，第三和第一进气通道的轴线中心线的交点与该交点的上游 的第二和第一进气通道的轴向中心线。 因此，来自第三进气口的燃烧室中的进气旋流比来自第二进气口的进气产生的进气强。 然后，围绕设置在燃烧室中心的火花塞周围的涡旋被加强。 此外，通过使用外部涡流和火花塞周围的涡流之间的速度差产生进气的湍流，导致改善的可燃性。 此外，通过相对地减小燃烧室的外周周围的漩涡来防止气缸的冷却损失。
