A method for actuating an element () in the air supply tract () of an internal combustion engine (), characterized in that the element () is actuated such that it opens the air supply tract () before the pinion () engages into the toothed ring () of the internal combustion engine ().

Method for actuating an element in the air supply tract of an internal combustion engine, in particular a throttle flap

The invention relates to a method for restarting an internal combustion engine, in which a first cylinder (ZYL) has a low air level and a second cylinder (ZYL) has a high air level, and wherein a predefined speed threshold value (ns) is selected as a function of said air levels. A method for the restart is selected and carried out as a function of a comparison of the determined speed (n) of the internal combustion engine with the predefined speed threshold value (ns).

Method and device for controlling an internal combustion engine

In a method for starting an internal combustion engine () having multiple combustion chambers (), wherein said internal combustion engine () has a starting system () and is operated using a start-stop function, and wherein said starting system () is actuated after a stop phase in operation of said internal combustion engine () to restart said internal combustion engine (), a combustion chamber () to be ignited first of the multiple combustion chambers () is determined upon a restart of the internal combustion engine (), and after a first ignition of the combustion chamber () to be ignited first, speed data for the internal combustion engine () are detected, and a starter release of the starting system () is caused if the detected speed data meet a predetermined starter release criterion.

Method for starting an internal combustion engine with start-stop function

In a method for operating a direct-injection internal combustion engine, a position of at least one piston inside a cylinder in which the combustion engine is at a standstill is determined; and a starting cylinder into which fuel is injected first is selected for a start following the standstill. An instantaneous charge of the starting cylinder is determined as a function of a duration of the standstill of the combustion engine. A distance (d) between the piston of the starting cylinder and a specified position of the piston is calculated. A minimum distance of the piston of the selected cylinder is determined as a function of the instantaneous charge; and another cylinder is selected as starting cylinder if the distance (d) between the piston of the starting cylinder and the specified position is less than the minimum distance.
