ABSTRACT:
The invention relates to a method for controlling the air flow quantity supplied to an internal combustion engine per operating cycle, without reducing the throttle. The method is characterized in that: an accelerator pedal signal (γ) is detected, the value thereof depending on the position of the accelerator pedal; a rotational speed signal (n) is detected the value thereof depending on the rotational speed of the internal combustion engine; load collectives are formed from (γ) and (n); both the load collective-dependent opening time (tLi) of a gas outlet in the compression chamber of each cylinder of the internal combustion engine during the compression stroke, and the load collective-dependent fuel injection quantities (˜tLi) per operating cycle and cylinder are determined; and the advance angles are determined according to the load collectives. The inventive method is advantageous in that only negligible fluctuations occur in the respectively introduced air flow quantity over all load regions.
