Abstract

A system for increasing the fuel feed in internal combustion engines during acceleration in order to ensure better performance comprising an acceleration detector, an enrichment stage, a proportionating member associated with a differentiating member, all connected to be responsive to at least one sensing member whose output signal is variable according to the engine operating conditions. The operating parameters sensed may be, for example, speed, air flow rate in the intake manifold, starting conditions, as well as the temperature of the internal combustion engine.
