Definitions

  • the invention relates to a cooling element e.g. for one Fuel injector and a Reciprocating internal combustion engine with fuel injector.
  • a separate cooling circuit contains the nozzle is a nozzle body with a needle seat and Nozzle holes and a cooling jacket, which the Encloses the nozzle body, the nozzle body with its Nozzle holes protrude from the cooling jacket.
  • the cooling jacket contains an inlet channel and an outlet channel for the Coolant and forms a with the valve body annular chamber in which the inlet and outlet channel flow out.
  • the cooling of the injection nozzle in the cylinder cooling integrated, the cooling jacket and the Nozzle body is arranged so that it is in a Cylinder cover trained chamber that protrudes part of the cylinder cooling circuit. In both cooling systems cooling water is passed through the chambers.
  • both systems have the disadvantage on that the distance between the area of Heat exposure and the range of the cooling effect relative is big.
  • the invention has for its object a cooling element to create, in which the disadvantages are eliminated.
  • the channels are designed as blind bores and Blind holes near the area of heat end up.
  • the cooling channels are open on one side and flow into a common space to a free one To cause passage of the cooling medium.
  • One fuel injector for one Reciprocating internal combustion engine is according to the invention with the Characterized feature of the claim.
  • Through the positive connection between the cooling element and Nozzle body ensures good heat transfer.
  • a reciprocating internal combustion engine with one Fuel injection nozzle is according to the invention by Characterized feature of the claim.
  • FIG. 1 to 3 show one as a cylindrical body device 1 shown and a sleeve shown cooling element 2 and according to the invention Arrangements of cooling channels in the cooling element are trained.
  • the cooling channels are as bores trained and the inlet openings are with a predetermined division.
  • the cooling channels are 3 designed as through holes.
  • the cooling channels 3 are inclined and inclined with respect to the body axis 4 trained, i.e. the pitch circle diameter D for the Inlet openings 5 is larger than that Pitch circle diameter d of the outlet openings 6 and Outlet openings 6 are in relation to the inlet openings 5 offset by an angle.
  • each cooling channel 8 is one Radial bore 9 assigned to an outlet opening 10 create.
  • cooling channels 11 designed as blind bores and with respect to Body axis 4 arranged inclined. To be added that the blind bores at a distance h of approx. 3 mm from the End of the sleeve.
  • FIG. 4 shows the arrangement of a device for Fuel injection in a cylinder cover or head 21.
  • the device comprises a cooling element 22, which in a hole is pressed into the cylinder cover 21, one Injection nozzle 23, which is arranged in the cooling element, and a flange 24, a spring assembly 25 and Fasteners 26, 27 to under the injector To keep bias in the cooling element.
  • the Components of an injection nozzle are known.
  • In the Injector 23 in question here has the Nozzle body 31 has a conical section 32, on the tapered end a number of nozzle holes 33 are formed and in which the needle seat is formed is.
  • An inner cone is formed in the cooling element 22, in which the conical section 32 of the nozzle body 31st sits, so that a positive connection exists is.
  • the injection nozzle is included Preload held in the inner cone, so that next to the positive connection also a non-positive connection is present.
  • Fig. 5 shows an injection nozzle of the above described type of a cooling element with a 2 is assigned to the cooling duct arrangement.
  • the Cooling element 41 is sleeve-shaped. At the extent the cooling element has a coolant inlet or outlet in the form of recesses 42, 43 through webs (not shown) separated by approx extend half the circumference and with the cylinder cover 21st Form flow chambers for the cooling medium. This Chambers each have a number of cooling channels 8 in connection.
  • the cooling element 41 has a cylindrical section 44. Adjacent to the Section 44 is a second cylindrical section 45 with a larger outer diameter, which in a third cylindrical section 46 runs out.
  • the second section 45 forms with cylinder cover 21 annular flow chamber 47 for the cooling medium.
  • the cooling channels 8 are formed, only two radial bores 9 being shown in the figure are.
  • a cylinder cover points in the bottom area as is known, a channel system for a cooling circuit.
  • the cooling element 41 is designed and in Cylinder cover 21 arranged so that the cooling channels 8 with the cooling circuit in the cylinder cover in series are switched, the cooling medium in the forced pass flows through the cooling element. Flows during the forced run the coolant from the cylinder cooling circuit into the Inlet opening 42 and into those connected to it Cooling ducts 8. An evaporation or Condensation cooling.
  • the cooling medium flows through the radial bores 9 into the annular chamber 47 and flows through the radial bores 9 in the Cooling channels connecting the outlet opening in the Cylinder cooling circuit back.
  • Fig. 6 shows an injection nozzle
  • the cooling element 51 with a cooling channel arrangement according to FIG. 3 is.
  • the cooling element 51 has the cylindrical section 44 and a second cylindrical section 52, in which the cooling channels 11 are formed.
  • the Cooling element 51 is pressed into the cylinder cover 21 and forms with this a chamber 54 which with the Cooling circuit is connected. In this version flows the cooling medium in free passage from the cooling circuit through the chamber and back into the cooling circuit.
  • the sleeve-shaped cooling element has a plurality of Cooling channels 8, which are oblique with respect to the sleeve axis 4 and / or inclined in the longitudinal extension of the Cooling element are formed. With this arrangement the area of cooling effect to the area of Heat exposure adjusted. If the cooling element Cooling an injector Reciprocating internal combustion engine applied, so the Cooling channels connected in series with the cylinder cooling will.
