Abstract
An arrangement for controlling a supply of air and a volume of fuel to an auxiliary combustion chamber associated with a supercharged internal combustion engine. The auxiliary combustion chamber being adapted to periodically deliver additional exhaust gas to an exhaust gas turbine of the supercharger as a function of an instantaneous exhaust gas volume from the internal combustion engine. A sensor is disposed in a charging air line of the internal combustion engine for influencing a pressure detector which delivers an actual value signal corresponding to the instantaneous charging air pressure. The signal reaching a comparator by way of an input amplifier, in which comparator the signal is compared with a guide parameter delivered by a fixed value adjustment device and corresponding to the desired constant charging air pressure. The resultant differential between the desired constant charging air pressure and the actual value forms an input signal for a proportional regulator whose output signal is fed to two curve adjustment elements which are respectively connected in series with an air supply regulator and/or a force amplifier to control the fuel volume.
