Abstract

An electronic engine r.p.m. limiter for use with an electronic ignition system controlled by a magnetic pulser generating pulses having a frequency proportional to the engine speed. An amplifier-waveshaper at the input of the limiter device supplies a control signal both to the electronic ignition circuit and to the remainder of the limiter device. This remainder converts the incoming pulse signals to a D.C. signal varying in accordance with the engine speed and compares this variable D.C. signal with a fixed D.C. (threshold) signal. When the variable D.C. signal exceeds the fixed threshold, an actuator circuit becomes operative to short-circuit the control signals for the electronic ignition, thereby cutting off the operation thereof until the engine speed is below a predetermined maximum limit.
