Abstract: A method is provided for operating an internal combustion engine that includes, but is not limited to ascertaining a possible instant of a stoppage of the internal combustion engine and injecting fuel to fill a cylinder of the internal combustion engine. The injection performed shortly before the instant of the stoppage of the internal combustion engine.

Abstract: A control unit is provided for fuel supply regulation during a cold-running phase of an internal combustion engine, that includes, but is not limited to an input port for inputting a combustion signal about the presence of a rich or lean combustion of a fuel mixture in the internal combustion engine, a P-element for providing a P-manipulated variable, which sets a fuel reduction upon the presence of a rich combustion and sets a fuel increase upon the presence of a lean combustion, an I-element for providing an I-manipulated variable, which sets a fuel increase, and an output port for controlling a fuel supply, the P-manipulated variable and the I-manipulated variable substantially offsetting one another during the cold-running phase upon the presence of a rich combustion in the stationary state.

Abstract: A method is provided for operating an engine that includes, but is not limited to checking if a clutch pedal is depressed. If this is the case, the setpoint value for the rotational speed is predetermined to a target idle speed and a target torque is predetermined. Following this it is checked if the clutch pedal is in a position in which it is no longer depressed, and if the neutral gear sensor indicates that a gear is engaged. If this is the case, the setpoint value of the rotational speed of the engine and/or the torque reserve are increased. Otherwise, the setpoint value of the rotational speed of the engine and the torque are left.
