Abstract
A control circuit for a fuel injection system of an internal combustion engine supplies a corrective current to the main multivibrator during and/or after engine starting. The corrective current is supplied on the basis of temperature dependent signals and on the basis of the pulse width of the primary injection signals, which is related to engine rpm and load.
