摘要: Intake holes at the opposite ends are opened and closed by first intake valves. The middle intake hole is opened and closed by a second intake valve. A control device includes an intake variable valve device. First branch channels are connected to the intake holes and produce a normal tumble flow. A second branch channel is configured such that the flow rate of intake air passing through the middle intake hole is relatively greater on the side closer to the outer periphery of the combustion chamber. Where increasing the flow coefficient is given a higher priority, a three-valve drive mode is selected. Where the strength of the normal tumble flow is enhanced, a two-valve drive mode is selected. Where production of the normal tumble flow is reduced, a one-valve drive mode is selected.

摘要: A cylinder head and induction passage arrangement for a three intake valve internal combustion engine wherein the center intake passage and its porting arrangement is directed so as to augment the tumble action caused by the side valve seats and their intake passages. The construction also provides that the center intake valve will be disposed so that there will be no shrouded area in the path of flame from the spark plug so as to ensure complete combustion. The cylinder head is made in such a way that the same cylinder head may be used for either bank of an engine having angularly inclined cylinder banks through the machining of only one face thereof.

摘要: 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.

摘要: A number of embodiments of intake passages for internal combustion engines wherein it is possible to obtain a tumble and tumble and swirl action or both under some running conditions and substantially unrestricted flow under high speed conditions so as to improve volumetric efficiency while, at the same time, increasing turbulence under the conditions when the flow pattern is altered. The flow pattern is controlled by a rectifier plate which extends through at least one of the intake passages and divides it into two flow areas, one of which is closed by a control valve which engages the rectifier plate in its flow controlling position so as to provide a stop for the control valve. The control valve is configured and oriented so as to provide substantially unrestricted flow paths in each of its positions. Embodiments incorporating carbureted and fuel injected engines are depicted.
