Abstract (en)

[origin: EP0886058A2] An apparatus for controlling fuel pressure in an engine. An accumulator, or a common rail (4), stores highly pressurized fuel sent from a pump (6). Injectors (2) inject fuel stored in the common rail (4) into combustion chambers of the engine. An ECU (50) controls a pressure control valve (10), which is provided in the pump (6), to adjust the fuel pressure in the common rail (4) according to the running state of the engine. When a key switch (52) is turned off to stop the engine, the ECU (50) adjusts the fuel pressure in the common rail (4) to a value that is suitable for subsequently restarting the engine. Therefore, starting of the engine is improved. <IMAGE>
