ABSTRACT:
The present invention relates to a regulating arrangement for metering a supplementary quantity of air for improving the combustion in internal combustion engines or afterburning of exhaust gases. The amount of air entering the regulating arrangement is metered as a function of the engine speed by means of an air pump driven by the engine. Part of the air entering the regulating arrangement is removed and returned depending on predetermined parameters. An auxiliary device responds to an emergency signal for the immediate shutoff of the fuel or fuel-air mixture used in the combustion. The emergency signal is transmitted by means monitoring the fuel-air ratio within substantially narrow tolerance limits of a predetermined threshold value.
