| 摘要 |
The invention relates to a fuel injection system, in particular for a common rail injection system of an internal combustion engine, comprising a pump housing (1) in which a driveshaft (3) and at least one pump piston (4) that interacts with the driveshaft (3) are arranged in a fuel-filled engine compartment (2). The engine compartment (2) is connected to a low-pressure system of the injection system, and the driveshaft (3) is mounted by means of a first bearing (5) and a second bearing (6). A recess (7) is provided in the pump housing (1) between the engine compartment (2) and the low-pressure system, and an insert part (8) is arranged in the recess (7). Furthermore, the insert part (8) has at least one radially and/or axially arranged bore (9) for a quantity of lubricant in order to ensure a lubricant and coolant quantity for the engine compartment (2) of the high-pressure fuel pump.
