Description

Beschrei- Luftverdichtende Brennkraftmaschine, die für den Bebung: trieb mit schwer brennbaren Kraftstoffen geeignet ist.Description: Air-compressing internal combustion engine suitable for operation with hardly combustible fuels.

Stand der Es ist bekannt, daß bei herkömmlichen luftverdichten-Technik: den Brennkraftmaschinen die Glühkerze folgende Aufgaben hat:State of the art It is known that in conventional air compression technology: internal combustion engines the glow plug has the following tasks:

- Erwärmen des Brennraumes (Vorkammer, Wirbelkammer oder ähnliches)- Heating the combustion chamber (prechamber, swirl chamber or similar)

- Kraftstoffteilchen, die in der Aufbereitungsphase sind, zu entzünden und die Verbrennung einzuleiten- to ignite fuel particles that are in the processing phase and initiate combustion

- So weit als möglich, am Rande des Brennraumes zu sitzen, um die Gemischbildung (Verwirbelung) nicht zu beeinträchtigen.- Sit as close to the edge of the combustion chamber as possible so as not to impair the mixture formation (turbulence).

Problem: Herkömmliche luftverdichtende Brennkraftmaschinen sind nicht in der Lage, mit schlecht brennbaren und dicken (zähen) Kraftstoffen zu starten, insbesondere bei niedrigen Temperaturen.Problem: Conventional air-compressing internal combustion engines are unable to start with poorly combustible and thick (viscous) fuels, especially at low temperatures.

Ferner sind herkömmliche Gemischbildungssysteme nicht in der Lage, oben genannte Kraftstoffe für den Startvorgang und für den Betrieb zu zerstäuben und somit zündfähig zu machen (wegen deren Viskosität). Des weiteren reicht die von herkömmlichen Brennkraftmaschinen erzeute Verdichtungsendtemperatur sowie die Wärmeleistung der Glühkerze nicht aus, um zündunwillige Kraftstoffe und solche mit hohem Flammpunkt sicher zu entzünden.Furthermore, conventional mixture formation systems are not able to atomize the above-mentioned fuels for the starting process and for operation and thus make them ignitable (due to their viscosity). Furthermore, the final compression temperature generated by conventional internal combustion engines and the heat output of the glow plug are not sufficient to safely ignite fuels that are difficult to ignite and those with a high flash point.

Lösung: Die mit der Erfindung erreichte Lösung besteht darin, daß eine Glühkerze zum Einsatz kommt, welche weit in den Brennraum hineinragt und so ausgerichtet ist, daß der unzerstäubte Kraftstoffstrahl, welcher aus der Einspritzdüse austritt, vollständig oder großenteils auf die heiße Glühkerze auftrifft. Daraus ergeben sich folgende Eigenschaften:Solution: The solution achieved with the invention consists in using a glow plug that extends far into the combustion chamber and is aligned so that the unatomized fuel jet that exits the injection nozzle hits the hot glow plug completely or largely. This results in the following properties:

1. "Aufreißen" des KraftstoffStrahles.1. "Tearing open" of the fuel jet.

2. Zerstäubung des auftreffenden Strahles.2. Atomization of the incident jet.

3. Verdampfen des Kraftstoffes aufgrund der hohen Temperatur der Glühkerze.3. Evaporation of fuel due to the high temperature of the glow plug.

4. Entzündung des so aufbereiteten Kraftstoffes.4. Ignition of the fuel thus prepared.

5. Aufgrund der Länge der Glühkerze (Glühstift) ist es möglich, die Energiezufuhr in Form von Wärme in den Brennraum wesentlich zu steigern, was einen Startvorgang entscheidend verbessert.5. Due to the length of the glow plug (glow pin), it is possible to significantly increase the energy supply in the form of heat into the combustion chamber, which significantly improves the starting process.

6. Verbesserung der Gemischaufbereitung während des Betriebes.6. Improvement of mixture preparation during operation.

Die Glühkerze (1) ist so im Brennraum (6) plaziert, daß der unzerstäubte Einspritzstrahl (4), welcher aus der Einspritzdüse (7) austritt und auf den um den Betrag (2) verlängerten Glühstift (5) auftrifft. Dies hat zur Folge, daß der Kraftstoffstrahl wie in (3) zu sehen ist, aufbereitet wird, am Glühstift (5) verdampft und gezündet wird.The glow plug (1) is positioned in the combustion chamber (6) in such a way that the unatomized injection jet (4) which exits the injection nozzle (7) and hits the glow plug (5) which has been extended by the amount (2). This means that the fuel jet is prepared as shown in (3), evaporates at the glow plug (5) and is ignited.

Positiv wirken sich auch die auftretenden Verwxrbelungen im Bereich des Glühstiftes aus.The distortions that occur in the area of the glow plug also have a positive effect.

.1.1 Begriff: Luftverdichtende Brennkraftmaschine, die für den Betrieb mit schwer brennbaren Kraftstoffen geeignet ist, dadurch gekennzeichnet,Term: Air-compressing internal combustion engine that is suitable for operation with hardly combustible fuels, characterized by Anspruch 1: daß eine Glühkerze zum Einsatz kommt, welche weit in den Brennraum (Wirbelkammer, Vorkammer oder Direkteinspritzer) hineinragt.Claim 1: that a glow plug is used which extends far into the combustion chamber (swirl chamber, pre-chamber or direct injection). Anspruch 2; Claim 2; Die Position der Glühkerze im Brennraum ist dadurch gekennzeichnet, daß die Glühkerze je nach Brennraum so zu plazieren ist, daß der Einspritzstrahl genau oder teilweise auf die in Betrieb befindliche Glühkerze auftrifft und dort aufbereitet wird.The position of the glow plug in the combustion chamber is characterized by the fact that, depending on the combustion chamber, the glow plug must be positioned in such a way that the injection jet hits the glow plug in operation exactly or partially and is processed there.
