Title: Fuel pressure controlling device of internal combustion engine
Inventor: NAKABAYASHI KATSUHIKO
IPC: F02M37/00
Filed: 2003-01-28
Abstract: <P>PROBLEM TO BE SOLVED: To prevent fuel leakage from an injector (fuel injection valve) during stoppage of an internal combustion engine to improve starting performance and emission.  <P>SOLUTION: A fuel pump 11 is driven to obtain a target fuel pressure detected by a fuel pressure sensor 17 of a fuel supply system including a fuel supply pipe 14 during operation of the internal combustion engine. In this case, a throttle portion 22 in a return pipe 21 has a very small cross-section ratio with respect to the fuel supply pipe 14 and has no influence on the target fuel pressure. When the fuel supply pump 11 is stopped, fuel is returned to a fuel tank 10 side through the throttle portion 22 and the return pipe 21 until the fuel pressure becomes stop fuel pressure by a first pressure regulator 23. Unwanted fuel leakage from the injector 16 is thus prevented during stoppage of the internal combustion engine, a required time for fuel pressure rise from the stop fuel pressure to the target fuel pressure is shortened when the internal combustion engine is started, and the starting performance and emission are improved.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
