ABSTRACT:
A device for metering fuel in an internal combustion engine which comprises sensors for operating parameters, an acceleration detecting stage with a subsequently connected pulse generating stage as well as a pulse lengthening stage, and a fuel metering system wherein the acceleration detecting stage is indirectly and/or directly associated with at least one of a plurality of components including an oscillation stopper (to prevent renewed triggering in case of an oscillation-carrying input signal), a blocking stage (for unequivocal and secure triggering), a repetition stopper (to avoid multiple triggering during gradual and longer-term signal rises), and a switching suppressor (to prevent a voltage rise after a switching step from being evaluated as an instance of acceleration) so that the device serves to operate the acceleration enrichment of the fuel-air mixture for the internal combustion engine with a minimum of disturbance thereby attaining optimum acceleration processes.
