ENGINE SPEED AND DIRECTION CONTROL |
摘要 |
<p>ENGINE SPEED AND DIRECTION CONTROL An engine control wherein a shaft driven by the engine causes a first signal to be generated and then a second signal after the shaft has rotated through a predetermined degree. The first signal starts a timer into operation, the timer producing a timer pulse of predetermined duration. Time coincidence of the timer signal and second signal indicates that a critical engine speed has been reached and such time coincidence is used to effect a control function. If the shaft rotates in the opposite direction the sequence of generation of the first and second signals in such direction is detected and used to generate a reverse-direction signal which is used to effect a control function. An automatic impedance-changing circuit enables the control to be used with a wide range of batteries.</p> |
