Abstract: The present invention is to prevent mixing of fresh air and an air-fuel mixture when a throttle valve is fully opened and increase a delivery ratio. A main nozzle (30) is surrounded by a tunnel-like air flow guiding member (52). The air flow guiding member (52) is opened at its front and back sides. A whole amount of fuel discharged via a main nozzle (30) is sent to a downstream side by an air flow created by the air flow guiding member (52). When a throttle valve (22) and a choke valve (24) are both in a fully-opened state, fresh air flows into an air-fuel mixture passage (12) through a gap between these valves (22, 24).

Abstract: An intake control system for a multi-cylinder combustion engine with control valves positioned within intake passageways that can vary the cross-sectional area of the intake runners to increase air intake velocity at low engine speeds. The control system includes an inner frame that can be inserted into a lower manifold after manufacture. The inner frame includes a plurality of flapper valves that are actuated by a four-bar link design, which is driven by a hypoid gear-set. The control system controls an internal DC electric motor that actuates a worm-drive gear-set, which in turn drives the hypoid gear-set to either engage or retract the flapper valves within the intake passageways.

Abstract: The present invention provides an intake control device that appropriately restricts the flow of intake air when a valve body is set to a restriction position while the valve body is smoothly operated. The valve body is configured such that it is supported so as to be capable of swinging with respect to a sleeve, and when the valve body is set to the restriction position, a main valve portion of the valve body is lifted upward from a bottom plate, and a secondary valve portion of the valve body is sunk into an accommodating space of the bottom plate. In the accommodating space, a stepped portion that allows outward displacement from an inner surface of the sleeve is formed, and a seal portion that is brought closer to the stepped portion when the valve body is set to the restriction position is formed in the secondary valve portion.

Abstract: The intake system has a valve seat, a plate valve, and an elastic sealing member. A path is provided to pass through the valve seat and to communicate with an intake passage of an internal combustion engine. The plate valve fits to or separates from the valve seat to close or open the path. The plate valve is provided with through holes passing through the plate valve in the thickness direction at a valve periphery part. The through holes are arranged linearly one after another in a peripheral direction of the plate valve to be offset to each other in the direction perpendicular to the peripheral direction. The elastic sealing member includes an elastic covering part that covers a first surface and a second surface of the plate valve and elastic coupling parts that are disposed in the through holes and are coupled with the elastic covering part at the first surface and the second surface.

Abstract: Methods and systems are provided for a parallel arrangement of at least two valved aspirators, with a high pressure source such as an intake throttle inlet coupled to a motive inlet of the arrangement and a low pressure sink such as an intake throttle outlet coupled to a mixed flow outlet of the arrangement. Intake throttle position and respective valves arranged in series with each aspirator of the arrangement are controlled based on intake manifold pressure and/or a desired engine air flow rate, for example such that a combined motive flow rate through the arrangement increases as intake manifold pressure increases. An intake throttle with a fully closed default position may be used in conjunction with the arrangement; during a fault condition where the intake throttle is fully closed, the valves of the arrangement may be controlled to achieve a controllable engine air flow rate during the fault condition.
