Method and apparatus for pressure reducing valve to reduce fuel pressure in a common rail |
摘要 |
It is a objective of the present invention to provide a control apparatus which is capable of compensating a delay time for opening a pressure reducing valve since an electronic control unit sends a command signal for driving the pressure reducing valve so as to discharge high pressure fuel in a fuel accumulating device of a fuel injection system for the internal combustion engine. The delay time control apparatus for opening a pressure reducing valve has a potential for avoiding an overshoot phenomenon in which an actual pressure of fuel accumulated in the fuel accumulating device overshoots a target value of fuel pressure during the increase the fuel pressure of the fuel accumulating device.
