Abstract
A method of actuating a throttling element in the intake system of an air-compressing fuel-injected internal combustion engine, which in low load and speed ranges is held in the closing position and in central and high load and speed ranges is held in an opening position. The throttling element in each operating point of the internal combustion engine is adjusted to that opening position which corresponds to an absolute pressure, determined from a load-dependent and speed-dependent characteristic diagram, in the intake system downstream of the throttling element, the setpoint value for the absolute pressure being corrected as a function of further operating parameters of the internal combustion engine.
