Description
Einspritzbrennkraftmaschine mit mindestens einer am Umfang des Zylinders angebrachten Vorkammer Die Erfindung betrifft eine Einspritzbrennkraftm.aschine mit mindestens einer am Umfang des Zylinders angebrachten Vorkammer, die durch eine zweckmäßig kurze Drosselstelle mit dem Hauptverbrennungsraum verbunden ist.Injection internal combustion engine with at least one on the circumference of the cylinder attached prechamber The invention relates to an injection internal combustion engine with at least one antechamber attached to the circumference of the cylinder, which is through a expediently short throttle point is connected to the main combustion chamber.
Gemäß der Erfindung wird in bekannter Weise die gesamte Brennstoffladung der Vorkammer unmittelbar durch Einspritzen zugeführt, und der Kolben übersteuert in seiner äußeren Totlage die .Drosselstelle oder Drosselstellen mit seinem äußeren Ende, er verengt sie somit gegen Ende des Verdichtungs- und zu Beginn des Arbeitshubs.According to the invention, the entire fuel load is in a known manner the antechamber is fed directly by injection, and the piston is overridden in its outer dead position the .Drosselstelle or throttle points with its outer End, it narrows it towards the end of the compression stroke and at the beginning of the working stroke.
Durch dieses übersteuern der Drosselöffnung werden die zwischen der Vorkammer und dem Hauptverbrennungsraum sich abspielenden Strömungen so beeinflußt, daß harte Zündungsschläge unterbleiben. Der Gang des Motors wird somit ruhiger als bei Vorkammermotoren, deren Übertrittskanal von der Vorkammer zum Hauptverbr ennungsraum angesteuert ist.By overriding the throttle opening, the between the The antechamber and the main combustion chamber are influenced in such a way that that hard ignition strikes do not occur. The gear of the engine is thus quieter than In the case of pre-chamber engines, the transfer channel from the pre-chamber to the main combustion chamber is controlled.
Es sind zwar Motoren bekannt, bei denen eine Drosselstelle zwischen dem Zylinderraum und einer am Zylinderumfang angeordneten Nebenkammer durch den Kolben übersteuert wird, wobei aber der in einer anderen Drosselstelle eingelagerte Brennstoff gegen Ende des Verdichtungshubes durch die in die Nebenkammer hinein auftretende Luftströmung mitgerissen und zerstäubt wird. Bei diesen Motoren ist also die Art der Brennstoffzufuhr ganz anders als beim Erfindungsgegenstand.Although there are engines known in which a throttle point between the cylinder space and a secondary chamber arranged on the cylinder circumference through the Piston is overridden, but the stored in another throttle point Fuel towards the end of the compression stroke through the into the secondary chamber occurring air flow is entrained and atomized. With these engines is So the type of fuel supply is quite different from that of the subject of the invention.
Auf der Zeichnung sind in zwei Abbildungen zwei Ausführungsbeispiele des Erfindungsgegenstandes im Längsschnitt durch Zylinder und Kolben dargestellt.In the drawing, there are two exemplary embodiments in two figures of the subject matter of the invention shown in longitudinal section through cylinder and piston.
Der Zylinder ist bei beiden Ausführungsbeispielen mit N bezeichnet, der Kolben mit g, die am Zylinderumfang angeordnete Vorkammer oder Vorkammern mit b und die Einspritzdüse mit a. Jede Vorkammer b ist mit dem Zvlinderraum d durch eine kurze Drosselstelle c verbunden. Im Zylinderdeckel sind das Einlaßventil e und das Auslaßventil f untergebracht. Die Düse a ist so angeordnet, daß sie den Brennstoff gegen die Drosselstelle hin einspritzt.In both exemplary embodiments, the cylinder is designated with N, the piston with g, the prechamber or pre-chambers arranged on the cylinder circumference with b and the injection nozzle with a. Each prechamber b is connected to the cylinder space d by a short throttle point c. The inlet valve e and the outlet valve f are housed in the cylinder cover. The nozzle a is arranged so that it injects the fuel against the throttle point.
Beim ersten Ausführungsbeispiel nach Abb. i ist nur eine Vorkammer b angeordnet. Die Drosselstelle c wird dabei von der zylindrischen Lauffläche des Kolbens g beinahe ganz zugesteuert, wenn dieser in seiner in der Zeichnung angegebenen inneren Totlage sich befindet.In the first embodiment according to Fig. I there is only one antechamber b arranged. The throttle point c is from the cylindrical running surface of the Piston g almost completely closed when this is indicated in its in the drawing inner dead position is located.
Das zweite Beispiel nach Abb.2 unterscheidet sich vom ersten nur dadurch, daß außer einer Vorkammer mit feststehendem Verbindungskanal c auch noch eine zweite Vorkammer angeordnet ist, deren Drosselstelle sich aus mehreren engen Löchern zusammensetzt und überdies in Richtung des Kolbenhubs verstellt werden kann. Mit Hilfe der verstellbaren Drosselstelle können jeweils die bestmöglichen Verhältnisse eingestellt werden.The second example according to Figure 2 differs from the first only in that that in addition to an antechamber with a fixed connecting channel c also a second Antechamber is arranged, the throttle point is composed of several narrow holes and can also be adjusted in the direction of the piston stroke. With the help of the adjustable Throttle point can be set to the best possible conditions.
