Abstract
The invention is directed to an electronic control apparatus for forming a fuel-metering signal for an internal combustion engine wherein increased fuel metering occurs during the start and post-start phases of the engine. With the electronic control apparatus, an index is formed for the pressure in the intake manifold of the engine and the gradient of the index is formed. The increased metering of fuel is reduced in dependence upon the gradient.
