ABSTRACT:
An electronic fuel control system of the type providing metered quantities of fuel to a power producing engine in response to accurately timed electrical pulses includes circuit means for overcoming oscillations in the pulses due to a reduction in system supply voltage occurring, for example, during engine cranking. The circuit means senses when the supply voltage is below a predetermined level and thereupon is operative to eliminate the oscillations without interfering with normal system operation.
