  • the invention relates to a fuel injector for a diesel engine according to the preamble of the independent claim. Especially The invention relates to a fuel injector for a two-stroke large diesel engine such as that used to power ships is used.
  • the valve seat is typically the Fuel injection nozzle relatively far from the nozzle holes through which the fuel enters the combustion chamber of the cylinder has several reasons. Firstly, the valve seat must be strong enough be supported to withstand the pressure loads resulting from the high Injection pressures result in being able to absorb. This requires one mechanically robust arrangement that takes up a relatively large amount of space. There but typically several injectors are provided per cylinder, it would be difficult, at least due to space constraints, the areas of Injection nozzles that are in the immediate vicinity of the combustion chamber are mechanically sufficiently robust.
  • the cylinder head is usually so thick that these areas of the injection nozzles can hardly be cooled and therefore in the Operation are exposed to very high temperatures. These high Temperatures would easily cause the valve seat to malfunction. Also for this reason, the valve seat is usually further away from the Nozzle holes arranged so that it is further away from the Exposure to the heat of combustion.
  • the valve spool has one upper area, which has a valve part, which with the main valve seat interacts, and a lower area that is a secondary Has closure member, which is located in the uncooled valve area.
  • the secondary locking member is designed so that it is closed State of the valve spool, that is, when the valve part of the Valve spool is sealingly in the main valve seat, the fuel passage closes immediately above the nozzle holes.

  • the fuel injector 1 functions as follows. Of the Fuel is e.g. B. by means of an injection pump, not shown the feed line 12 is conveyed into the first pressure chamber 6 and acted upon there the first nozzle needle 7. When the fuel pressure in the first pressure chamber 6 is greater than the prestress caused by the compression spring 16, the first nozzle needle 7 raised and thus opens the passage on the first Valve seat 8. The fuel flows through the connecting lines 13 into the second pressure chamber 9 and there acts on the second nozzle needle 10.
  • the second nozzle needle 10 from the second valve seat 11 raised and thus opens the passage to the Nozzle holes 31, so that the injection process begins, that is, the Fuel through the nozzle holes 31 into the combustion chamber of the cylinder entry.
  • the fuel pressure increases in the first Pressure room 6 from.
  • the first nozzle needle 7 in the first valve seat 8th pressed and closes the passage from the first pressure chamber 6 into the Connection lines 13.

  • the second is supported Nozzle needle 10 from the spring 21 in the nozzle body 2 is mechanical separated from the first nozzle needle 7.
  • This mechanical decoupling of the two nozzle needles 7,10 has the particular advantage that the opening or.
  • Closing pressure that means the fuel pressure in the second Pressure chamber 9, in which the passage on the second valve seat 11 by lifting or lowering the second nozzle needle 10 is opened or closed, can be set essentially independently of the first nozzle needle 7 can.

Only then does the second nozzle needle 10 the passage on the second valve seat 11 and Injection starts. As soon as at the end of the injection process Fuel pressure in the second pressure chamber 9 drops below the closing pressure the passage on the second valve seat 11 is practically immediately closed, so essentially no more fuel in the combustion chamber can reach.
