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, a device, a computer program and a computer program product for operating an internal combustion engine having a starter: a first threshold value and a second threshold value are specified; a first variable and a second variable are determined, which characterize the operating state of the internal combustion engine; the first variable is compared to the specified first threshold value and the second variable is compared to the specified second threshold value; and the starter starting, or not starting, the internal combustion engine as a function of the comparison result.

Method and device for starting an internal combustion engine

A method for starting an internal combustion engine that is operated with a fuel mixture made of at least two types of fuel. An injection of the fuel into combustion chambers of the internal combustion engine occurs starting at a predefined pressure threshold of the fuel in a fuel supply according to a high-pressure starting mode, and also according to a low-pressure starting mode if the predefined pressure threshold is no longer met. The pressure threshold is selected as a function of the mixture ratio of the fuel types in the fuel mixture. In this way it can be achieved that differences can be taken into consideration in the optimal mixture formation of the fuel types.

Method for fuel injection

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.

Method for operating an internal combustion engine, and control or regulating device for an internal combustion engine

A method for providing a correlation between a periodic analog/digital conversion and an angle-synchronous signal, in which the periodic analog/digital conversion is provided with a timing mark, which correlates with the angle-synchronous signal, and is assigned to an angular position of a device via this timing mark.
