Abstract: A method for operating a vehicle having a gasoline engine includes determining a density of a gasoline to be combusted in the gasoline engine, determining a stoichiometric air demand, determining a critical temperature from the density of the gasoline to be combusted and the stoichiometric air demand, and adapting countermeasures to prevent vapor bubbles based on the determined critical temperature.

Abstract: A device for discharging fuel vapor from a fuel supply system for an internal combustion engine has a container which is situated in the fuel supply system and contains liquid fuel under an upwardly limited pressure. A discharge line, which leads to a tank venting system, leads out of the container. The device also has a detector for detecting vaporous fuel in the container and a blocking device which is coupled to the detector and with which the discharge line can be opened or blocked depending on the detection.

Abstract: A cooling system after engine shut-down includes a pump, a coolant duct for a coolant, and at least one component to be cooled. The coolant duct is associated with a fuel pump. A cylinder head for an internal combustion engine and a method for operating the cooling system after engine shut-down are provided.

Abstract: A method for starting an internal combustion engine with a fuel tank and a low-pressure pump which pumps gasoline out of the fuel tank at a low-pressure to a high-pressure pump that pumps the gasoline at a high-pressure to injectors of the internal combustion engine. An electronic controller is provided for controlling and/or regulating the low-pressure pump, the high-pressure pump, and the injectors. After a start pulse for the internal combustion engine, the method: checks whether a formation of vapor bubbles in the gasoline is possible on the low-pressure side during a hot start. If not possible, then the normal low-pressure is set. If possible, then a low pressure which is high enough that the formation of vapor bubbles is not possible on the low-pressure side is set, and the normal low-pressure is set after a period of time. The problem of vapor bubble formation is prevented in an inexpensive or cost neutral manner via the method.
