Definitions

  • the present disclosure generally refers to a fuel injection system for supplying fuel as, e.g., heavy fuel oil to injection nozzles of a large internal combustion engine. Furthermore, the present disclosure refers to a fuel injection pump, as well as to a method for purging a fuel injection pump configured to pump fuel as, e.g., heavy fuel oil, of a large internal combustion engine.
  • a fuel injection system may be configured to supply fuel as, e.g., heavy fuel oil to a common rail of a large internal combustion engine.
  • the system may comprise a high-pressure fuel pump configured to supply fuel as, e.g., heavy fuel oil at high-pressure to a common rail.
  • the fuel pump may include a pump barrel extending along a longitudinal direction and having a barrel wall, and a plunger configured to reciprocate within the pump barrel and guided by the barrel wall. At least one scraper ring may be attached to one of the plunger and the barrel inner wall and may be configured to slide along the other of the plunger and the barrel inner wall.
  • a method for purging a fuel injection pump configured to pump fuel as, e.g., heavy fuel oil, of a large internal combustion engine within, e.g., a ship or generator set, may comprise the method step of mechanically scraping or wiping off any deposits on a plunger or an barrel inner wall of the fuel injection pump during reciprocating motion of the plunger.
  • the same method may be applicable to a fuel pump which may be configured to supply fuel as, e.g., heavy fuel oil to a common rail of a large internal combustion engine.
  • Fig. 1 shows a schematic block diagram of an exemplary embodiment of a fuel injection system 100 configured to supply fuel as, e.g., heavy fuel oil to injection nozzles 105 of a large internal combustion engine 5.
  • each injection nozzle 105 may be connected to an associated fuel injection pump 110 via a high-pressure fuel line 115.
  • one fuel injection pump 110 may be configured to supply fuel as, e.g., heavy fuel oil to a plurality of fuel injection nozzles 110.
  • Each fuel injection pump 110 may be connected to a fuel reservoir 120 via fuel supply lines 116.
  • a scraper ring 220, 220', or 220" may have a slit so that insertion of ring in the associated groove 215 may be facilitated.
  • a scraper ring 220, 220', or 220" may comprise two or more ring segments to be inserted in the associated groove 215, 215', 215".
