    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).

    摘要： An intake system for an engine allows supercharging using the dynamic effect of intake air has a surge tank (4Q,4L) for a cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a second surge tank (4b,4R) for another cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a first upstream intake passage (5g,5L) for supplying intake air to the first surge tank, a second upstream intake passage (5g,5R) for supplying intake air to the second surge tank, a connecting tank (9) for communicating intermediate portions of the individual intake passages (6a- with each other, and a short connecting passage (31) for communicating upstream portions of the first upstream intake passage and the second upstream intake passage with the connecting tank (9). When the number of engine revolution is high, intake air is supplied to each of the cylinders through the connecting tank and the individual intake passage by taking advantage of the short connecting passage and bypassing a long upstream intake passage and the surge tank. Further, the short connecting passage does not adversely affect the effect to be produced by resonant supercharging because the upstream portion of the intake passage is communicated with the connecting tank. The intake system can shorten the length of passage for supplying intake air when the number of engine revolution is high due to inertia supercharging, without sacrificing the effect to be achieved by resonant supercharging.
