Abstract: The injection system of a fuel injection pump is provided. In the injection system of a fuel injection pump, a plunger performs a reciprocating slide motion in the axial direction inside of the plunger chamber of a barrel for compressing fuel. The plunger has a release groove and a control edge. A spill port is formed in the wall surface of the barrel. A damping groove is formed in the upper-part outer circumference of the control edge and provides a fine fuel flow path. The damping groove meets the spill port in advance to form the fine flow of fuel from the plunger chamber to the spill port before the control edge of the plunger meets the spill port to release pressure.

Abstract: The present invention relates to a fuel injection pump having a variable pressure chamber which can adjust a fuel injection timing according to each engine load with a simple structure and a lower manufacture cost compared to the conventional injection pump without a separate apparatus for moving a barrel as well as not modifying a shape of a plunger.The fuel injection pump having the variable pressure chamber further includes a pressure adjustment means including a contact plug of which lower portion is inserted and installed in the upper cover; a cylinder of which lower portion is inserted and installed in the contact plug and having the variable pressure chamber formed inside thereof; a main fuel pressing hole formed in the upper cover and the barrel to connect the variable pressure chamber of the cylinder and a plunger insertion hole of the barrel; a piston installed in the variable pressure chamber of the cylinder to enable an upward and downward sliding motion thereof; and a manual pressure adjustment unit installed on an upper portion of the cylinder to enable a vertical height adjustment to elastically support the upper portion of the piston.
