Definitions

  • the invention relates to a system for attachment of High-pressure fuel injection pumps on cylinder heads of reciprocating internal combustion engines.
  • This is a one-cylinder high-pressure fuel injection pump actuated by at least two additional cams, located at the end of an im Cylinder head running and for controlling the gas exchange valves responsible camshaft. These cams in turn actuate one Tappet, which in turn drives a high-pressure fuel injection pump, which is here connected directly to the cylinder head frictionally.
  • the receiving bore for the tappets required for operation the high-pressure fuel injection pump additional processing steps of already very expensive to manufacture cylinder head. Should z. B. from an already produced in series reciprocating internal combustion engine without High-pressure fuel injection pump additionally a variant with High-pressure fuel injection pump will be manufactured for the manufacturer Part complexity increased.
  • the Attachment of a high-pressure fuel injection pump to a cylinder head a reciprocating internal combustion engine to improve such that a Enlargement of the cylinder head is not necessary.
  • no should additional machining of the cylinder head may be required, as well as the simple Retrofittability of an already in production Reciprocating internal combustion engine with a high-pressure fuel injection pump be guaranteed.
  • the holder for attachment of High-pressure fuel injection pumps is designed so that it includes a camshaft bearing bridge.
  • the existing Drill holes originally only for mounting a camshaft bearing bridge are intended to be used here for attachment of the holder according to the invention. Therefore, compared to a cylinder head variant without High-pressure fuel injection pump no additional processing steps on Cylinder head needed. To ensure sufficient stability of the holder ensure, however, is still a third mounting or Auflagerdazzling necessary.
  • two or more Camshaft bearing bridges through the bracket for fastening High-pressure fuel injection pumps replaced. This is a particularly easy too realizing variant that is not constructive or production-related Require changes to the cylinder head of a reciprocating internal combustion engine.
  • the prior art is high-pressure fuel injection pumps by means of or to drive several located on a shaft cam.
  • This Tappet is usually designed as a bucket tappets, as the tappets Operation can absorb arising side forces.
  • the ram then drives turn on the high-pressure fuel injection pump.
  • the present invention has the holder for attachment of high-pressure fuel injection pumps additionally one or a plurality of bores for receiving at least one plunger Camshaft bearing bridges as holding for aggregates can serve are known per se (US-A-4 913 105 , EP-A-0 353 988)
  • the above-mentioned plunger from a cam already present for driving the gas exchange valves the camshaft actuated has the advantage that no additional components, no additional space and no additional processing steps in the Comparison to a variant without the holder according to the invention for attachment required by high-pressure fuel injection pumps.
  • the use of two or more cams is like that possible to increase the drive frequency of High-pressure fuel injection pump and thus to increase the Kraftstofcharacter oriental.
  • the holder is dimensioned so that the space is bridged up to a cylinder head cover.
  • the high-pressure injection pump on the outside of a Hubkolbenbrennkraftmaschine be flanged. This allows a simple Assembly of the high-pressure injection pump and the associated fuel and Electrical connections.
  • Figure 1 is a erfihdungssieer holder 1 for attachment of High-pressure fuel injection pumps 7 in a perspective view shown. Other adjacent parts are in the manner of an explosion drawing added. Evident are a camshaft 2, a plurality of cams 3 for Actuation of gas exchange valves, an additional cam 5 for actuation a running in a hole 9 tappet 4 and a section a cylinder head cover 6 with sealing plate 10 and seal 11 and a High-pressure fuel injection pump 7.
