Title: Fuel injection system

This patent describes a fuel injection system for a diesel engine comprising: condition detection means for detecting operating conditions of the diesel engine including a rotational position thereof; low pressure fuel supply means for supplying fuel at a low pressure at an output port thereof; high pressure fuel pump means, having a pump chamber communicating with the output port of the low pressure fuel supply means, and plunger means reciprocable within the pump chamber for introducing fuel from the output port of the low pressure fuel supply means into the pump chamber during a movement in a predetermined direction of the plunger means and for pressurizing the introduced fuel during a movement of the plunger means in the opposite direction so that pressurized fuel is delivered from the high pressure fuel pump means at an output port thereof; common rail fuel storage means, connected to the output port of the high pressure fuel pump means, for storing pressurized fuel delivered from the high pressure pump therein at a substantially continuous pressure.
