    • An engine timing input system (400) is described for pulse detonation engines that allows for accurate engine timing when rotary or cylindrical valves are used to distribute an air/fuel mixture for combustion. The invention uses a profile disk (160) having a predetermined circumferential edge (405) corresponding to valve position to provide for accurate engine timing. A frequency wheel (170) is used in conjunction with the profile disk (160) to provide a more accurate representation of valve position by partitioning the valve position into multiple pulses during each rotation of the rotary or cylindrical valve. The profile disk (160) and frequency wheel (170) when used with programmable timing circuitry signal fuel valve timing and ignition relative to the rotating valve.
    • 描述了用于脉冲爆震发动机的发动机定时输入系统(400),其允许当使用旋转或圆柱形阀来分配用于燃烧的空气/燃料混合物时的精确发动机定时。 本发明使用具有对应于阀位置的预定周向边缘(405)的轮廓盘(160),以提供准确的发动机定时。 变频轮(170)与轮廓盘(160)一起使用,以通过在旋转或圆柱形阀的每次旋转期间将阀位分配为多个脉冲来提供阀位置的更准确的表示。 当与可编程定时电路一起使用时,轮廓盘(160)和频率轮(170)将信号燃料气门正时和点火相对于旋转阀。
