Abstract

The engine comprises a combustion chamber and a pre-combustion chamber. A small amount of the fuel is guided via a non-return valve (1) to the pre-combustion chamber (4) until the piston exerts a compressive pressure in the combustion chamber when moving from bottom dead centre upwards which is larger than the pressure in the pre-combustion chamber. In this way air from the combustion chamber (5) is pushed via the channels (6) in the pre-combustion chamber and the non-return valve is closed. The rich fuel-air mixture is ignited by a spark plug (3) in the pre-combustion chamber and is pushed under high pressure via the channels to the combustion chamber. It is mixed in the combustion chamber with fuel directed through discharge holes (7) from a fuel valve (2). In this way the fuel is vigorously mixed, ignited and completely burnt.

Description

Die Erfindung betrifft ein Verfahren zum Betrieb von Brennkraft­ maschinen für gasförmige Brennstoffe, bestehend aus einem Zylin­ der mit Kolben und einer Vorbrennkammer.The invention relates to a method for operating internal combustion machines for gaseous fuels, consisting of a cylinder the one with pistons and a pre-combustion chamber.

Es ist bereits ein Verfahren zum Betrieb von Brennkraftmaschinen mit einer Vorbrennkammer bekannt, wobei in der Vorbrennkammer ein relativ fettes Brennstoff-Luft-Gemisch eingeleitet wird, die heiße Verbrennungsluft über einen Verbrennungskanal in den Hauptbrennraum einströmt und das in dem Hauptbrennraum befindliche magere Brennstoff-Luft-Gemisch zur Zündung bringt (DE 29 33 231). Dieses Verfahren ist jedoch nur zweckmäßig, wenn eine äußere Gemischbildung mit der Ansaugluft erfolgt. Die äußere Gemischbildung hat als Nachteil einen schlechteren Wirkungsgrad gegenüber Verfahren mit innerer Gemischbildung.It is already a process for operating internal combustion engines known with a pre-combustion chamber, being in the pre-combustion chamber a relatively rich fuel-air mixture is introduced, the hot combustion air via a combustion duct in the Main combustion chamber flows in and in the main combustion chamber located lean fuel-air mixture ignites (DE 29 33 231). However, this procedure is only useful if external mixture formation with the intake air takes place. The outer Mixture formation has the disadvantage of poorer efficiency compared to processes with internal mixture formation.

Weiterhin wurde ein Verfahren zum Betrieb von Verbrennungsmotoren mit gasförmigen Wasserstoff bekannt, wobei Wasserstoff sowohl durch äußere Gemischbildung, als auch ab einer bestimmten Lei­ stung durch zusätzliche Direkteinspritzung und damit innere Gemischbildung, dem Verbrennungsmotor zugeführt wird (DE 37 31 986).Furthermore, a method for operating internal combustion engines was developed known with gaseous hydrogen, both hydrogen by external mixture formation, as well as from a certain lei by additional direct injection and thus internal Mixture formation, the internal combustion engine is supplied (DE 37 31 986).

Dieses Verfahren hat den Nachteil, daß ein erheblicher apparati­ ver Aufwand für das gleichzeitige Betreiben der inneren und äußeren Gemischbildung erforderlich ist.This method has the disadvantage that a considerable apparatus ver effort for the simultaneous operation of the inner and external mixture formation is required.

Es ist Aufgabe der Erfindung ein Verfahren zum Betrieb von Ver­ brennungsmotoren mit gasförmigen Brennstoffen vorzuschlagen, bei dem unter Vermeidung eines hohen apparativen Aufwandes ein hoher Wirkungsgrad erzielt wird.It is an object of the invention a method for operating Ver propose internal combustion engines with gaseous fuels, with the avoidance of a high expenditure on equipment high efficiency is achieved.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein kleiner Teil des Brennstoffes solange über ein Rückschlagventil in die Vorbrennkammer geleitet wird, bis durch den sich vom unteren Totpunkt nach oben bewegenden Kolben ein Kompressionsdruck im Brennraum erzeugt wird, der größer ist als der Druck in der Vorbrennkammer, so daß Luft vom Brennraum über die Kanäle in die Vorbrennkammer gedrückt und das Rückschlagventil geschlossen wird, das in der Vorbrennkammer befindliche fette Brennstoff- Luft-Gemisch durch die Zündkerze gezündet, mit hohem Druck über die Kanäle in den Brennraum geleitet und mit dem im gleichen Zeitpunkt über das Brennstoffventil und Austrittsbohrungen nachströmenden Brennstoff intensiv vermischt, gezündet und voll­ ständig verbrannt wird.According to the invention the object is achieved in that a small Part of the fuel as long as a check valve in the Pre-combustion chamber is passed through by the bottom  Dead center moving piston a compression pressure in the Combustion chamber is generated, which is greater than the pressure in the Pre-combustion chamber, so that air from the combustion chamber in through the channels pressed the pre-combustion chamber and closed the check valve the fat fuel in the pre-combustion chamber Air mixture ignited by the spark plug, at high pressure the channels are directed into the combustion chamber and with the same one Time via the fuel valve and outlet holes inflowing fuel intensively mixed, ignited and full is constantly burned.

Erfindungsgemäß wird die Hauptbrennstoffmenge zentral und mittig durch die Vorbrennkammer und über Austrittsbohrungen in den Brennraum geführt.According to the invention, the main amount of fuel becomes central and central through the pre-combustion chamber and through outlet holes in the Firing chamber led.

Vorteil der erfindungsgemäßen Lösung ist, daß durch Verbindung des Vorkammerverfahrens mit dem Verfahren der inneren Gemischbil­ dung sowohl ein hoher Wirkungsgrad als auch eine vollständige und schadstoffarme Verbrennung von gasförmigen Brennstoffen mit an sich geringer Zündfähigkeit erreicht wird. Das Vorkammer­ verfahren mit dem Vorteil einer sicheren Zündung wird erstmalig für gasförmige Brennstoffe angewandt. Dadurch können gasförmige Brennstoffe, die gar nicht oder nur unzureichend während der Kompression im Brennraum zur Selbstzündung gebracht werden, gezündet und mit hohem Wirkungsgrad vollständig und abgasarm verbrannt werden. Durch die innere Gemischbildung wird der größt­ mögliche Wirkungsgrad dadurch erzielt, daß kurz vor Erreichen des oberen Totpunktes unter hohem Druck stehender Brennstoff in den Brennraum eingebracht wird.The advantage of the solution according to the invention is that by connection the pre-chamber process with the process of the inner mixture bil both high efficiency and complete and low-pollution combustion of gaseous fuels is achieved with low ignitability per se. The antechamber procedure with the advantage of a safe ignition becomes the first time applied to gaseous fuels. This can be gaseous Fuels that are not at all or insufficient during the Compression in the combustion chamber can be auto-ignited, ignited and complete with high efficiency and low emissions be burned. Due to the internal mixture formation, it becomes the largest possible efficiency achieved by shortly before reaching top dead center fuel under high pressure is introduced into the combustion chamber.

Nachfolgend soll die Erfindung anhand eines Ausführungsbeispiels näher erläutert werden.In the following, the invention is to be illustrated using an exemplary embodiment are explained in more detail.

Bei dem erfindungsgemäßen Verfahren wird über ein Rückschlagven­ til 1 der Vorbrennkammer 4 gasförmiger Brennstoff zugeführt, zu einem Zeitpunkt, zu dem sich der Kolben in der Nähe des unte­ ren Totpunktes befindet. Ab einem vom Rückschlagventil 1 bestimm­ ten Kompressionsdruck wird die Zufuhr des gasförmigen Brennstof­ fes beendet. Bei weiterer Kompression dringt komprimierte Luft über die Kanäle 6 in die Vorbrennkammer 4 ein und vermischt sich mit dem gasförmigen Brennstoff. Bei Erreichen des Zündzeit­ punktes wird das in der Vorbrennkammer 4 befindliche Brennstoff- Luft-Gemisch durch eine in die Vorbrennkammer 4 ragende Zündkerze 3 gezündet. Zum etwa selben Zeitpunkt wird das Brennstoffventil 2 geöffnet und die Hauptmenge des Brennstoffes über die Aus­ trittsbohrungen 7 in den Brennraum 5 eingeblasen. Durch die Verbrennung in der Vorbrennkammer 4 entsteht eine hohe Temperatur des verbrennenden Gemisches, was bewirkt, daß dieses heiße Ge­ misch in den Brennraum 5 über die Kanäle 6 einströmt und dort auf die aus dem Brennstoffventil 1 ausströmenden kalten Strahlen trifft. Dabei werden diese Strahlen gezündet und die gesamte im Brennraum 5 befindliche und die über das Brennstoffventil 1 nachströmende Brennstoffmenge verbrennt schadstoffarm mit hohem Wirkungsgrad.In the method according to the invention, gaseous fuel is supplied to the pre-combustion chamber 4 via a return valve 1 at a time at which the piston is in the vicinity of the bottom dead center. From a compression valve determined by the check valve 1 , the supply of the gaseous fuel is stopped. With further compression, compressed air penetrates into the pre-combustion chamber 4 via the channels 6 and mixes with the gaseous fuel. Upon reaching the ignition point of the fuel contained in the precombustion chamber 4 air mixture is ignited by a spark plug projecting into the pre-combustion chamber 4. 3 At about the same time, the fuel valve 2 is opened and the majority of the fuel is blown into the combustion chamber 5 through the outlet bores 7 . The combustion in the pre-combustion chamber 4 produces a high temperature of the burning mixture, which causes this hot Ge mixture to flow into the combustion chamber 5 via the channels 6 and meet the cold jets flowing out of the fuel valve 1 there. These jets are ignited and the entire amount of fuel located in the combustion chamber 5 and flowing in via the fuel valve 1 burns with a low level of pollutants with high efficiency.
