Fuel injection system for internal combustion engines |
摘要 |
The invention relates to a fuel injection system for internal combustion engines, having a high-pressure feed pump that pumps fuel from a supply tank into a high-pressure common rail that communicates with the various injection valves via high-pressure lines. To increase the injection pressure to up to 2000 bar, the injection valves have a booster piston, which is guided axially on the valve member of the injection valve and with one end face defines an injection pressure chamber that communicates with the injection ports, and with its other end face defines a work chamber that can be made to communicate with the common rail.
