    • An apparatus for improving engine performance at wide-open throttle or full load by supercharging the induction system. An expanded/enlarged volume plenum is divided into two chambers. each containing a group of three openings for flowing air past inlet valves to three cylinders of a six cylinder engine, for example. A pair of adjustable length intake runners are connected to the upstream end of the plenum and are adjusted with changes in engine speed to resonantly tune the induction system for the speed changes to effect greater input of air to the cylinders. A valve can be opened to communicate the chambers with each other to further resonantly tune the system at intermediate speeds. At the higher engine speeds, resonant tuning in conjunction with the ram induction of air into the cylinders further increases the mass flow of air.
    • 一种用于通过对感应系统进行增压来提高在大开度节流阀或满负荷下的发动机性能的装置。 扩大/扩大的容积室被分为两个室。 每个包含一组三个开口,用于将空气通过入口阀流动到例如六缸发动机的三个气缸。 一对可调节长度的进气通道连接到集气室的上游端,并随着发动机转速的变化进行调节,以便对感应系统进行谐波调谐,以实现速度变化,从而实现更大的气缸输入。 可以打开阀门以将腔室彼此连通,以进一步在中间速度下谐振地调谐系统。 在较高的发动机转速下,共振调谐与空气进入气缸的冲击进一步增加了空气的质量流量。
