Verbrennungskraftmaschine mit Kompressionszündung Internal combustion engine with compression ignition

Die Erfindung bezieht sich auf eine Verbrennungskraftmaschine mit Kompressionszündung. |The invention relates to an internal combustion engine with compression ignition. |

Bei Verbrennungskrafbmaschinen mit Kompressionszündung ist man bestrebt, eine möglichst große Füllung dös Zylinders mit Luft zu erhalten mit dem Zweck, die Leistung der Verbrennungskraftmaschine auf ein Maximum zu steigern. Diese Aufgabe kann durch die Verwendung von Einlaß- undIn internal combustion engines with compression ignition, the aim is to have as large a filling as possible to get dös cylinder with air with the purpose of increasing the performance of the internal combustion engine to a maximum.

Auslaßventilen größten Durchmessers und Einlaß-» und Auslaßkanälen gelöst werden·, deren Querschnitt ein Maximum ist und deren Form so ausgebildet ist, daß die Strömung möglichst stoßfrei hindurchgeht.Largest diameter exhaust valves and intake »and Outlet channels are solved ·, the cross section of which is a maximum and whose shape is designed so that the flow passes through as smoothly as possible.

Es ist bekannt, zur Vergrößerung der Querschnittsfläche der Ein- und Auslässe mehr als zwei Ventile zu verwenden. Diese an sich bekannte Lösung ist aber kostspielig und kompliziert darüber hinaus die Steuerung der Ventile. Die Verbesserung der herkömmlichen Verbrennungskraftmaschinen besteht erfindungsgemäß darin, daß bei einem Motor mit direkter Einspritzung, mit einer zentrisch zu der Achse des Zylinders liegenden Verbrennungskammer, einem Einlaßventil und einem Auslaßventil, die Achsen derselben zu der Achse des Zylinders geneigt verlaufen, wobei dem den Boden des Zylinders bildenden Teil eine halbkugelförmige oder kegelstumpf förmige Gestalt gegeben wird. Auf diese Weise ist es möglich, einen Durchgangsquerschnitt eines jeden Ventiles vorzusehen, welcher gegenüber den bekannten Anordnungen ganz erheblich größer ist.It is known to increase the cross-sectional area of the inlets and outlets by more than two Valves to use. However, this solution, known per se, is expensive and, moreover, complicated the control of the valves. The improvement of the conventional internal combustion engines consists according to the invention in that, in the case of a direct injection engine, with one centered on the axis of the cylinder Combustion chamber, an intake valve and an exhaust valve, their axes to the axis of the cylinder run inclined, the part forming the bottom of the cylinder being hemispherical or truncated shaped shape is given. In this way it is possible to have a passage cross section of each Provide valve, which is considerably larger than the known arrangements.

Die Erfindung kennzeichnet sich dadurch, daß ein jeder Zylinder eine in dem Kopf des Kolbens angeordnete und gegenüber der Achse des Zylinders zentrierte Verbrennungskammer mit direkter Einspritzung, ein Einlaßventil und ein Auslaßventil besitzt, und daß die AchsenThe invention is characterized in that each cylinder has one located in the head of the piston and a direct injection combustion chamber centered on the axis of the cylinder, an intake valve and has an outlet valve, and that the axes
