Title:
【発明の名称】内燃機関のための行程制御と圧力制御とを組み合わせた燃料噴射方法及び燃料噴射機構
Document Type and Number:
Japanese Patent JP2003507639
Kind Code:
A
Abstract:
In a method for injecting fuel at at least two differently high fuel pressures via injectors into the combustion chamber of an internal combustion engine, the fuel injection at the lower fuel pressure takes place under stroke control, and the fuel injection at the higher fuel pressure takes place under pressure control. For a pre- and/or post-injection and/or a boot injection at the lower fuel pressure, the control chamber and via a check valve the nozzle chamber as well are connected to a low-pressure fuel supply, and that for a main injection at the higher fuel pressure, the nozzle chamber is connected to the high-pressure fuel supply.
