  • Patent number: 7438051
    Abstract: A method and a device for supplying fuel to internal combustion engines comprise a regulated high-pressure system and a controlled low-pressure system, wherein an adaptation value for correcting the desired preliminary pressure is detected in an adaptation mode, in order to adjust a variable preliminary pressure in the low-pressure system. For this purpose, the preliminary pressure is specifically changed in the adaptation mode until vapor bubbles are detected by a regulator response of the high-pressure regulator of the high-pressure system. When vapor bubbles are detected, current process parameters of the fuel supply system are determined and the adaptation value is derived therefrom.
