    摘要: A three plenum air distribution manifold for intake air to internal combustion engine with long, narrow runners leading from first and second spaced side plenums for delivery of air and recirculating exhaust gases into corresponding combustion chambers of the engine. One end of the spaced side plenums are connected by an acoustically balanced cross over passage selectively closed by a manifold tuning valve for improving engine output torque during low engine speed. A third plenum is positioned intermediate the two side plenums to communicate with the combustion chambers in bypass relation to the side plenums thereby directly supplying air to the combustion chambers through short runners which are selectively opened by valves to optimize engine torque over a higher range of engine speeds. The manifold tuning valve and short runner valves are controlled by an onboard electronic controller responsive to signals from the engine corresponding to parameters such as engine speed. The short runner valves are connected to a short runner valve shaft, and a biasing assembly applies a load to selected journal locations for the shaft to reduce oscillations of the shaft and the potentially resulting chatter. Further and endplay control assembly limits total endplay to non-uniform expansion or contraction between the plastic manifold and the metal short runner valve shaft and short runner valves.

    摘要: A throttle valve actuator (10) for an internal combustion engine includes a throttle body (12) for defining at least one aperture or passageway (14) extending therethrough to deliver a charge to a combustion chamber in communication with the aperture (14). At least one valve (16) is mounted on a shaft for rotating within the aperture (14) of the throttle body (12) to control the internal combustion engine. A crank arm (20) is connected to the shaft (18) for driving the valve (16) in rotation between a first position and a second position. A pliant cable (22) is connected to the crank arm (20) at an anchor point (24) adjacent one end of the pliant cable (22). The pliant cable (22) transmits a force to the crank arm (20) to control rotation of the valve (16) connected thereto. A cam (34) is connected to the crank arm (20) for modifying an effective moment arm of force being transmitted between the pliant cable (22) and the crank arm (20), such that the moment arm rapidly decreases during a first angular portion of rotation about the shaft (18) from the first or closed position and substantially stabilizes during a second angular portion of rotation about the shaft (18) to the second or open position.

    摘要: A three plenum air distribution manifold (10) for intake air to internal combustion engine with long, narrow runners (50,52,54,64,66,68) leading from first (22) and second (24) spaced side plenums for delivery of air and recirculating exhaust gases into corresponding combustion chambers of the engine. One end of the spaced side plenums (22,24) are connected by an acoustically balanced cross over passage (34) selectively closed by a manifold tuning valve (42) for improving engine output torque during low engine speed. A third plenum (14) is positioned intermediate the two side plenums (22,24) to communicate with the combustion chambers in bypass relation to the side plenums thereby directly supplying air to the combustion chambers through short runners (80-90) which are selectively opened by valves (96) to optimize engine torque over a higher range of engine speeds. The manifold tuning valve (42) and short runner valves (96) are controlled by an onboard electronic controller (46) responsive to signals from the engine corresponding to parameters such as engine speed. The short runner valves (96) are connected to a short runner valve shaft (98), and a biasing assembly (112) applies a load to selected journal locations for the shaft (98) to reduce oscillations of the shaft and the potentially resulting chatter. Further and endplay control assembly limits total endplay to non-uniform expansion or contraction between the plastic manifold (10) and the metal short runner valve shaft (98) and short runner valves (96).
