Definitions

  • a known fuel injection valve for internal combustion engines (DE 10 2005 036 951 A1) designed as a so-called multi-hole injection valve has a valve seat body which terminates a hollow-cylindrical valve seat carrier and delimits a valve chamber connected to a fuel supply.
  • a valve seat in the form of an annular surface concentrically surrounding the axis of the valve seat body and a plurality of injection holes are formed in the valve seat body.
  • the valve seat forms with a closing body of a valve seat carrier axially displaceably arranged valve member a final injection ports sealing seat. The valve member is acted upon by a closing head on the valve seat aufpressenden valve closing spring.
  • Each of the plurality of spray holes has an upstream, small cross-section hole inlet portion with a hole inlet opening and a downstream, larger cross-sectional hole exit portion with a hole outlet opening.
  • the hole inlet openings of all injection holes lie within the valve seat forming annular surface on the valve body and the hole outlet openings of all the injection holes in the side facing away from the valve chamber, convex outer body wall of the valve seat body.
  • the injection valve according to the invention with the features of claim 1 has the advantage that air can flow from the outside into the hole outlet sections through the groove connecting all hole exit sections of the injection holes, so that a sufficient ventilation is provided and thus the pressure conditions in the hole exit sections are positively changed.
  • the valve closing phase no negative pressure is now generated in the hole outlet sections by the emerging wake flow, which pulls the fuel film built up during the injection phase on the wall surfaces of the hole outlet sections in the direction of hole outlet openings.
  • the escape of the fuel film from the hole outlet openings is suppressed, and the deposits resulting from the engine combustion do not occur at the sputtering-critical hole outlet openings, but in the interior of the hole outlet sections and are therefore no longer relevant to exhaust gas.
  • the soot emission of the internal combustion engine can be kept largely constant over its lifetime and avoided with increasing life so far accompanying increase in soot emissions in the exhaust gas.
  • the groove width is smaller than the diameter of the hole outlet openings.
  • the hole outlet openings are arranged on a divider circle and connecting the hole outlet openings groove formed annular.
  • FIG. 1 shows a detail of a longitudinal section of an injection valve for an internal combustion engine
  • FIG. 2 shows a bottom view of the injection valve in FIG. 1,
  • FIG. 3 a detail of a plan view according to arrow III in FIG. 1,
  • FIG. 1 The detail in Figure 1 with its injection-side end in longitudinal section schematically sketched injection valve for injecting fuel into a combustion cylinder of an internal combustion engine has a sleeve-shaped valve seat support 1 1, which protrudes from a valve housing, not shown here and is completed at its free end with a valve seat body 12 ,
  • a valve seat 14 in the form of an annular surface concentric with the axis of the valve seat body 12 is formed on the inner wall of the valve seat body 12 delimiting a valve chamber 13 and forms a so-called sealing seat together with a closing head 15 of a valve member 16 axially displaceable in the valve seat carrier 12.
  • the closing head 15 is attached to the front end of a hollow cylindrical valve needle 17 of the valve member 16, z. B. welded.
  • the valve needle 17 has radial bores 18 and communicates with a fuel inlet, not shown here, formed in the valve housing, so that fuel from the fuel inlet via the valve needle 17 and the radial bores 18 passes into the valve chamber 13 and there is under pressure at the sealing seat.
  • On the valve member 16 engages in a known manner to a valve closing spring 19 and an actuator 20, which are indicated schematically in Figure 1.
  • the actuator 20 is z. B. an electromagnet.
  • the valve closing spring 19 presses the closing head 15 onto the valve seat 14. By means of the electromagnetic actuator 20 of the closing head 15 is lifted against the restoring force of the valve closing spring 19 from the valve seat 14 more or less.
  • spray holes 21 are arranged in the valve seat body, each having at least two stepped in cross-section hole portions, namely an upstream hole inlet portion 22 with the smallest hole cross section and a hole inlet opening 221 and a downstream hole exit portion 23 with the largest hole cross-section and a hole exit opening 231st Between the upstream hole entry section 22 with the smallest hole cross section and the downstream hole exit section 23 with the largest hole cross section, further, with increasing cross section, stepped hole sections may be present. All hole inlet openings 221 on the one hand and all hole outlet openings 231 on the other hand lie on a pitch circle in mutually parallel planes which extend transversely to the axis of the valve seat body 12.
  • the hole inlet openings 221 of the hole inlet sections 22 lie in the valve body 13 delimiting the inner body wall of the valve seat body 12, in one of the trained as an annular surface valve seat 14, central zone of the inner body wall of the valve seat body 12, and the hole outlet openings 231 of the hole exit sections 23rd lie in the remote from the valve chamber 13, outer body wall of the valve seat body 12, in a dome-shaped here, central region of the valve seat body 12.
  • a trough-shaped recess 24 is formed, in which the hole inlet openings 221 lie.
  • the injection holes 21 are aligned in the valve seat body 12 so that their hole axes are inclined at an injection angle to the axis of the valve seat body 12. For deposits of burnt fuel at the peripheral edges of the
  • a groove 25 is incorporated in the remote from the valve chamber 13 outer wall of the valve seat body 12 so that it passes with downstream groove opening through all hole exit sections 23 and thus all hole exit sections 23 of the spray coupler 21 connects each other.
  • the groove 25 is formed annularly for this purpose.
  • the groove width is smaller than the diameter of the hole outlet openings 231.
  • Figure 3 and 4 are for a spray hole 21 in the valve seat body 12 groove 25 and spray hole 21 with hole inlet portion 22, hole inlet opening 221, hole outlet portion 23 and hole outlet opening 231 in plan view and section shown enlarged.
  • the injection holes 21 and the groove 25 are directly in the MIM

Abstract

L'invention concerne une soupape d'injection pour moteurs à combustion interne comportant un siège d'étanchéité formé par un siège de soupape (14) et une tête de fermeture (15) d'un pointeau de soupape (16) et plusieurs trous d'injection (21) disposés en aval du siège d'étanchéité. Les trous d'injection (21) étagés en section transversale présentent respectivement au moins une partie d'entrée de trou en amont (22) dotée de la plus petite section transversale de trou et d'une ouverture d'entrée de trou (221), et une partie de sortie de trou en aval (23) dotée de la plus grande section transversale de trou et d'une ouverture de sortie de trou (231). L'invention vise à éviter un dépôt non souhaité de carburant brûlé sur les bords des ouvertures de sortie de trou (231). A cet effet, toutes les parties de sortie de trou (23) sont reliées ensemble par l'intermédiaire d'une rainure (25) dotée d'une ouverture de rainure orientée vers l'aval.
