ABSTRACT:
A control device for internal combustion engines, especially for turbocharged diesel engines. The control device is arranged to generate a control distance proportional to the amount of air supplied to the engine. The control device includes a pressure chamber charged by the intake air pressure, which is separated from the back-pressure chamber by a membrane. A stop abuts against the membrane and is scanned via an intermediate lever by a supply volume adjustment element of a fuel pump. The reference absolute pressure in the back-pressure chamber is positioned between a throttle with variable throttle diameter and a throttle with fixed throttle diameter. A vacuum pump aspirates air via the throttle with fixed throttle diameter, connected to atmospheric pressure, and the throttle with variable throttle diameter is arranged to respond to the reference absolute pressure.
