Title:
リターンレス燃料供給システム内の燃料圧力を逃がす方法
Document Type and Number:
Japanese Patent JP4465138
Kind Code:
B2
Abstract:
The invention relates to a method for reducing the fuel pressure in a return-free fuel supply system of an internal combustion engine to a desired pressure value. At least one fuel pump is mounted in the fuel supply system. In order to be able to reduce the fuel pressure in the fuel supply system in a simple manner without additional pressure release valves, the suggestion is made that the fuel supply system and the internal combustion engine be operated in a pressure-reduction mode wherein at least one fuel pump of the fuel supply system is so controlled (open loop and/or closed loop) that the desired pressure value is adjusted in the fuel supply system. The fuel supply system is preferably configured as a common-rail storage injection system for a direct-injecting internal combustion engine.
