ABSTRACT:
An electronic timing circuit for an internal combustion engine includes a Schmitt trigger operated by timing pulses from a magnetic pick-up mounted on the engine. The upper trip point is set high when the pulses have a high amplitude due to a high engine speed, so that false triggering of the circuit by noise of lower amplitude is avoided. A lower trip point is automatically set when the pulses have a low amplitude, such as when the engine is cranked to start it.
