Definitions

  • the invention relates to a device for injecting fuel into a combustion chamber, in particular for injecting fuel into a cylinder of an internal combustion engine according to the preamble of claim 1.
  • This type of injector was, as from the document DE 44 07 360 A1 emerges, later evolved.
  • a corresponding injection nozzle with fan-shaped jet is further developed in that the jet can be rotated in the combustion chamber, so that the injected fuel quantity can be distributed to the desired amount of air.
  • a better distribution of the fuel is possible by twisting a fan beam, but this is a corresponding time required.
  • For optimal engine operation is a short and complete Combustion advantageous to use the resulting increase in pressure as efficiently as possible.
  • DE 10 2006 041 476 A1 a disc-shaped fuel injections by means of flat fan beams known. This injector injects in the longitudinal direction of the nozzle body.
  • the present invention has the object to optimize the injection or to optimize the combustion, in particular to reduce fuel consumption and to reduce the generation of adverse exhaust emissions.
  • a device is characterized in that the jet channels are arranged distributed over the peripheral surface of a nozzle body and that the fan levels of the multi-jet nozzles are aligned transversely and / or inclined to the geometric axis of the nozzle body, with regularly distributed double jet nozzles are provided so that a uniform planar distribution of fan beams, each delimiting narrow free zones, resulting in a free zone by omission or other positioning of a double jet nozzle can be increased and / or an entire fan beam can be spared.
  • the jet channels are distributed over the peripheral surface of the nozzle chamber in order to achieve a corresponding good spatial distribution of the spray region of the fuel.
  • a baffle zone according to the invention is already present when two or more fuel jets only touch or overlap in some regions, which already partly causes the inventive effect.
  • a multi-jet nozzle for example a double-jet nozzle, takes advantage of the fine atomization of such nozzles.
  • a fine atomization causes a rapid evaporation of the fuel with a largely homogeneous fuel-air mixture ratio.
  • the fine atomization provides a large surface area of the liquid fuel which is advantageous for such evaporation.
  • the large surface area is also advantageous when ignition has already taken place, since even with any existing liquid surface of fuel droplets, the combustion takes place considerably more effectively with a correspondingly large surface,
  • the combustion chamber can be spatially defined and sprayed in a short time, so that in a correspondingly small time interval, a good fuel air distribution in the combustion chamber is reached.
  • double-jet nozzles form a fan beam which spans substantially at the angle at which the partial beams impinge on one another.
  • colliding occurs a fine atomization, wherein the propagation direction of the fuel droplets almost completely away from the nozzle, which in turn is advantageous for a combustion process, since thus a load on the nozzles by soot or the like particles that may arise during combustion, is avoided .
  • a very flat fan beam can be formed by a double jet nozzle, whose extension, e.g. as angular expansion, in the fan plane defined by the two fuel jets is significantly larger than in the transverse direction to this fan level.
  • This circumstance can be advantageously used to selectively fill a shallow combustion chamber with a fuel mist.
  • an appropriate arrangement of the multi-jet nozzles or double jet nozzles can be achieved in a sense a nearly disc-shaped fuel distribution with very fine atomization. This is particularly advantageous in reciprocating engines, which have such a disc-shaped combustion chamber at the top dead center of the lifting movement.
  • Such a quasi disk-shaped fuel distribution is preferably achieved with multiple jet nozzles, the fan levels are aligned substantially parallel to the disk.
  • any other fuel distribution can also be achieved by appropriate arrangement of the fan levels.
  • a fan level may well be aligned parallel to the cylinder axis or to a center axis of an injector. Even inclined fan levels in oblique angle arrangements are possible.
  • different nozzle openings can also Penetration depth of the fuel can be influenced in the combustion chamber.
  • different multi-jet nozzles with different nozzle openings can also be used, as are multiple jet nozzles which have jet-dependent different nozzle openings.

  • a nozzle chamber common to two or more multiple jet nozzles from which the jet channels of the two or more multiple jet nozzles emanate.

  • an embodiment is possible in which jet channels of two double-jet nozzles intersect in the wall of the injection device, but the intersecting flow channels are separated from one another by this offset.
  • the fan levels of all multi-jet or double-jet nozzles are arranged in parallel. This results in a nearly disc-shaped spray area with the advantages indicated above. Although the slight offset between individual fan levels transversely to the fan levels entails a certain height extent of the spray area, it is still a substantially flat pronounced spray area of multiple multi-jet or double jet nozzles in different angular directions possible by such a configuration.
