ABSTRACT:
A control device for controlling a recycling of exhaust gases into an intake system of a self-igniting internal combustion engine which includes a signal generator, constructed as a pneumatic control slide valve mounted to a fuel injection pump. The signal generator is controlled by the respective instantaneous load conditions as a function of the rotational speed of the engine and the load on the engine by a non-reactive scanning of a position of a control rod associated with the fuel injection pump. The signal generator is coupled with the control rod and a pneumatic signal is transmitted by the signal generator in dependence upon a position of a control piston of the signal generator. The pneumatic control signal is transmitted to an adjusting member such as, for example, a pneumatic controller, compressed-air cylinder, or a valve, for each load condition of the engine associated with an exactly defined position of the control rod, with the control signal regulating an amount of recycled exhaust gases in accordance with an applied pressure.
