<p>A circuit is disclosed which includes a Schmitt trigger having a pair of control electrodes and which is responsive to a plurality of engine conditions to generate an output signal when the engine conditions indicate that a termination of fuel delivery to the engine is necessary. The circuit is preprogrammable to generate an output signal when the engine speed is in excess of a preselected value and a selected switch has changed state and to thereafter continue to generate the output signal while the switch state remains constant and until engine speed drops to a second, lower, preselected value.</p> |
