摘要:
The invention relates to a method for restarting an internal combustion engine, in which a first cylinder (ZYL1) has a low air level and a second cylinder (ZYL2) 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).

The invention relates to a method for stopping an internal combustion engine, wherein an amount of air which is supplied via an air metering device of the internal combustion engine, in particular a throttle flap (100), is reduced after a stopping order has been detected. According to the invention, the amount of air which is supplied via the air metering device of the internal combustion engine is again increased when the detected speed (n) of the internal combustion engine falls below a predefinable speed threshold value (ns), wherein an intake cylinder (ZYL2) to which the amount of air is supplied does not enter any working cycle after the amount of supplied air has been increased.
摘要:
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.

摘要:
A method is described for operating an internal combustion engine, the internal combustion engine including an angle of rotation sensor. In normal operation, a function is activated at a first angle of rotation. In stop operation, internal combustion engine is temporarily brought to a standstill. The function is activated in a start operation following the stop operation at a second angle of rotation, which follows the first angle of rotation in the direction of rotation.
摘要:
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.
