Definitions

  • the present invention relates to injection nozwater or other liquid cooling agent or with air.
  • the present invention is based on this fact and consists in that the injection nozzle is protected by means of insulation from the cylinder head side walls, hitherto considered as a cooling agent, and also in that the low temperature of the light oil itself is'used for cooling the nozzle.
  • the fuel is led to the nozzle in as cold a condition as possi-ble, and is protected therein from any heating by conduction or radiation from the engine cylinder.
  • the means used for this purpose consist rstly in a highly eflicient insulation of -the whole fuel path in and on the cylinder, and secondly, in decreasing to the minimum possible the quantity of fuel located in this region.
  • Fig. 1 shows in section such a nozzle which is formed in the known manner as an open injection nozzle with a simple check non-return valve
  • Fig. 2 shows in section a nozzle with external valve Spring.
  • Fig. 3 shows in section, a nozzle with its slaughters set in a predetermined direction, and Figs. 3a 4and 3b show two forms of a detail of Fig. 3.
  • Figure 1 a is a part of the cylinder or cylinder cover of a fuel injection engine operating 'on light oil.
  • b is the actual injection nozzle provided with atomizing ceremoniess h to which the fuel arrives through the bore g' which is made as narrow as possible.
  • Above said bore is provided a simple check non-retum valve e seated in a union member c. The whole nozzle body is constrained on its seat It -by means of the securing screw d.
  • the atomizer part b is protected from the cylinder walls by insulation f which may consist of asbestos, mica or any other suitable material, and for practical reasons the insulating material is held together by means of an insulating protecting sleeve t. 'I'he heat absorbing surface of the atomizer part b and the upper surface of the minf into this through the axial central aperture,
  • the insulating air Ilayer hereinabove described provides in a very complete manner the insulation for the nozzle cooled by the fuel, Fig. .2.
  • an ample air insulating space y which is in communication with thel outer air through the slit l formed in the screw thread.
  • the check non-return valve e is formed with an externally located spring and the atomizer part hjin the nozzle body u is screwed in from below. Similar to the securing screw in the preceding example, in this case the nozzle body u carries the heat radiating surfaces v.
  • Fig. 3 is shown, similar to Fig. l, an embodiment wherein the atomizing orifices h are set in a. determined direction by means of prismatic guides w.
  • the heat insulation is provided in that in the somewhat larger atomizer part b is inserted a filler tube
  • This simple form of insulation is based on the observation that the surface resistance to heat transmission is very considerable, and can replace an insulation o1' substantial thickness.
  • the inner tube z is therefore inserted so firmly that it remains seated in its aperture without any further securing means, but it is however provided with a certain thin insulating layer on its outer surface either by oxidation, or a very fine layer of graphite or carbon, or by being moistened with water glass before its insertion. It may also be provided with a slightly turned part or annular ring, but care must, however, be taken that this is so well sealed off above and below from the light oil, or is so firmly packed with insulating material, that any moistening with fuel is prevented.
  • the outer end of the tube .r may be adapted to act as a stop for the check non-return valve e which is, in this case, formed as a ball valve.
  • the air insulating space y in the present example is formed in-such a way that the part of the atomizing member b outside the seat k of the injection nozzle has a smaller diameter than that of the nozzle seat itself, so that in this way without any further increase in dimensions an ample heat insulating air layer is former.
  • the nozzle holding screw is screwed against the nozzle holder z which is provided with the above-mentioned aerating orifice i, and which in its turn is screwed in the cylinder a.
  • a filter cartridge is provided in the connecting part c consisting of the screw threaded member q, the tubular member m provided with an inclined slot and the filter o.
  • the filter consists of lead having very ne perforations or wire gauze, but preferably of a combination of fine wire sieves on the outer side and coarse gauze sieves on the inner side, capable of acting as a support.
  • the elements q, m and o may be advantageously formed together as a common cartridgelike member.
  • the outer fine gauze is advantageously made liner than the diameter of the nozzle apertures so that at this place those impurities of the fuel which were originally in the injection pump or which penetrate into the fuel by scaling oif from the pressure conduits, are retained.
  • a fuel oil injection nozzle for insertion in an opening in the cylinder wall of an internal combustion engine, said nozzle including a body portion having an axially-extending bore through which the fuel passes on its way to the cylinder, a part of said body portion being within the opening in the cylinder wall and spaced from the wall dening said opening to form an air space between said body portion and said wall and a part of said body portion extending outwardly beyond the cylinder wall, and a cap engaging said outwardly-extending portion and a portion secured to said cylinder wall to retain said body portion within said opening, said cap having openings through the top thereof, with air passages located between the air space surrounding that part of the body portion within the opening and the openings in said top to permit circulation of air through said air space, passages, and openings to effect cooling of said body portion.
  • a fuel oil injection nozzle as defined in claim 1 in which heat insulating material is applied to the outer surface of the body portion that is within the opening in the cylinder wail.
  • a fuel oil injection nozzle for insertion in an opening in the cylinder wall of an internal combustion engine, said nozzle including a body portion having an axially-extending bore through which the fuel passes on its way to the cylinder, the inner end of said body portion having a plurality of atoniizer orifices for injecting the fucl into the cylinder, a part of said body portion being within the opening in the cylinder wall and spaced from the wall defining said opening to -form an air space between said body portion and said wall, and a part of said body portion extending outwardly beyond the cylinder wall and having a radially-extending lug thereon, and means for retaining said body portion within said opening, said means having passages extending therethrough and communicating with the air space surrounding said body portion to permit circulation of air through said passages and air space to effect cooling of said body portion, and said radially-extending lug being confined between the spaced walls of one of said passages to retain the atomizer orifices in fixed position with respect to the cylinder.
  • a fuel injection nozzle for insertion in an opening in the cylinder wall of an internal combustion engine, said nozzle including a body portion having an axially-extending bore through Y which the fuel passes on its way to the cylinder.
  • the inner end of said body portion having a plurality of atomizer orifices for injecting the fuel into the cylinder, a part of said body portion being within the opening in the cylinder wall and spaced from the wall deiining said opening to form an air space between said body portion and said wall, and a.
  • a yfuel injection nozzle for insertion in an opening in the cylinder wall of an internal'combustion engine, said nozzle including a body portion having -an axially-extending fuel passage therethrough, a sleeve surrounding said body portion and spaced therefrom to provide an air space between saidsleeve and body portion, said sleeve having openings therethrough communicating with said air space, and a cap secured to said sleeve and enclosing and engaging the upper end of the nozzle body portion for retaining said body portion in Iiixed'positon within said sleeve, said cap having an air passage therethrough communicating with the air space between said sleeve and body portion.
