Abstract

Pulsations which falsify an output signal of an air mass meter occur at low and medium rotational speeds in a unit that supplies air to an internal combustion engine. A method for adjusting the load of the internal combustion engine limits an opening angle of an electromotively adjustable throttle valve to a rotational speed-dependent opening value which includes an opening base value that is between a lower and an upper limit value. In the case of the lower limit value, the full load of the engine is reached. In the case of the upper limit value, pulsations of the air in an intake duct upstream of the throttle valve do not yet occur.
