Abstract (en)

[origin: WO2006072285A1] The invention relates to a method and a device for supplying internal combustion engines with fuel. Said system comprises a controlled high-pressure system and a controlled low-pressure system. An adaptation value for correcting the desired preliminary pressure is detected in an adaptation mode, thereby adjusting a variable preliminary pressure in the low-pressure system. For this purpose, the preliminary pressure is specifically modified in the adaptation mode until vapor bubbles are detected by a governor response of the high-pressure governor. When vapor bubbles are detected, actual process parameters of the fuel supply system are determined and the adaptation value is derived therefrom.
