Abstract
An electronic fuel injection control includes a main fuel control circuit, a transient enrichment control circuit temporarily increasing fuel flow as a result of increasing of a demand signal, and temperature compensation means non-linearly varying the effect of the enrichment control with engine temperature. The temperature compensation means preferably includes a temperature 'window' detector which acts to increase the effect of the enrichment control whenever the engine temperature is between prescribed limits.
