Abstract:
1. A method for controlling the air flow of a combustion engine with direct fuel injection and at least one intake and one exhaust device per cylinder, said method comprising the steps of: providing a combustion engine having cylinders each including a combustion chamber, at least one controllable gas outlet per cylinder attachable to said compression chambers of said cylinders of said combustion engine, and at least one exhaust device attachable to each of said cylinders of said combustion engine, said exhaust device having exhaust valves; registering an accelerator pedal signal with a value (γ) depending on the position of said accelerator pedal, said accelerator pedal signal being registered by an accelerator pedal position sensor; registering a rotation speed signal with a value (n) depending on the rotation speed of said combustion engine, said rotation speed signal being registered by a rotation speed sensor which determines the rotation speed of a crank shaft of said combustion engine; defining load conditions using said value (γ) and value (n); determining a load-condition-dependent opening period (t determining a load-condition-dependent fuel injection quantity (˜t determining advance angles (ZW) as a function of said load conditions.
