    摘要: In an internal combustion engine, fuel is directly injected into at least one combustion chamber at least during a compression stroke in such a way that a stratified mixture is present in the combustion chamber. This mixture is then externally ignited. The fuel is introduced during the compression stroke by at least one main injection and an ignition injection, the ignition injection taking place immediately before an ignition and producing at least essentially no torque.

    摘要: A first method is for determining a variable, which characterizes a fuel injection, in an internal combustion engine of a motor vehicle in a hot-start situation wherein fuel is injected directly into at least one combustion chamber from a high-pressure region of a fuel supply system; the variable, which characterizes the injection quantity, is corrected at least in dependence upon a variable which represents a temperature of the fuel. A second method is for determining a hot-start situation in an internal combustion engine of a motor vehicle wherein a hot-start situation is determined at least based on a variable, which represents a temperature of the fuel, and based on a fuel pressure. The invention relates likewise to corresponding arrangements, a corresponding control apparatus for an internal combustion engine, a corresponding computer program having program-code means and a corresponding computer program product having program-code means.

    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.

    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.
