  • About the return line 22nd fuel flows back when the pressure in the high-pressure rail is a safety-critical one Exceeds limit. This can only occur in the event of a fault.
  • a leakage line, not shown the Hub Piston Fuel Pump (HDP) 16 discharges fuel contained in the Hub Piston Fuel Pump (HDP) 16 escapes between piston and cylinder. This amount is however relatively small.
  • the stroke piston fuel pump 16 includes, as shown in FIG. 2, a piston 40 in a cylinder 42 which performs a lifting movement. This lifting movement is divided into a downward and upward movement. In the downward movement is a displacement with fuel from the fuel tank 10 of the low pressure system 38 filled with fuel. In the upward movement the compression of the fuel takes place.
  • a quantity control station in the form of a Rate control valve 44 disconnects during a predetermined portion of the upstroke Compression space from the supply side or low pressure side 38. During that Section of the upward movement of the piston 40, which is used to compress the fuel is to be used, the bulkhead 44 separates the connection between engine capacity the stroke piston fuel pump 16 and supply line 46.
  • the quantity control 44 opens the connection between the displacement the stroke-piston fuel pump 16 and the supply line 46. A closing interval is created, which lies in the compression stroke of the stroke piston fuel pump 16.
  • the position of the interval in the compression stroke is in principle freely selectable. Usually will either the closing or the opening time to one of the dead points of the movement of the piston 40 is placed. With both concepts it is possible the effective compression stroke adjust.

In principle, it does not matter if the closing interval immediately after passing through the bottom dead center 54 begins (concept I, arrow 60) or ends with reaching the top dead center 52 (concept II, arrow 76). Both concepts lead to pressure build-up. For energetic reasons, however, the second concept (arrow 76) is preferable.
  • the compression process 60 or 76 is triggered by closing the quantity control station 44 with upwardly moving piston 40. The volume of fuel in the compression space at this moment is at approximately low pressure level. By the upward movement of the piston 40, the pressure increases.
  • the check valve 48 opens and the fuel flows out of the compression space of the reciprocating piston fuel pump 16 into the high-pressure rail 18. Dies takes place as long as the pressure in the compression chamber above the pressure p HD rail is maintained in the high-pressure rail 18.
  • the effective compression stroke is ended by opening the quantity-adjusting mechanism 44 or as soon as the piston 40 reaches its top dead center 52. Depending on the pump design and concept, a residual volume at the end of the compression process 58 may remain in the compression space of the reciprocating piston fuel pump 16.
