FUEL ACCUMULATOR AND FUEL SYSTEM USING THE SAME |
摘要 |
A fuel accumulator is provided to assist restarting a direct injection engine fuel system. The fuel accumulator includes a central guide post with a fuel passage. A cup shaped plunger with a closed end is slideably disposed on the central guide post. A seal means is disposed between the plunger and the central guide post to define a substantially sealed fuel chamber. A biasing means is provided to urge the plunger onto the central guide post. A fuel admission valve selectively prevents and permits fuel from entering and exiting the fuel accumulator. When a fuel system stop is commanded, pressurized fuel is admitted into the fuel chamber, thereby compressing the biasing means which maintains a restart pressure. When a fuel system start is commanded, pressurized fuel is expelled from the fuel accumulator.
