ABSTRACT:
A controlling device for controlling the supply of gases into combustion spaces of a self-igniting internal combustion engine includes a control member for regulating the flow of returned exhaust gas and an air throttle for regulating flow of sucked in air. The air throttle and the control member are linked to pneumatic setting motors which in turn are controlled by pressure transforming means operating with a source of a reference pressure and a source of control pressure. An output of the pressure transforming means is provided with electrically controlled switching means which selectively actuate respective setting motors. The electric control of the pressure transforming means and of the connecting means is made in dependency on operational variables of the engine.
