Abstract

The engine has two cylinders (1,3) arranged at an obtuse angle, which form a common combustion chamber (5). Pistons (2,4) move in the cylinders in opposite directions. Both cylinders use common fuel intake (6) and ignition (7) devices and common valves (8). The compression ratio can be varied by moving one or both crankshafts (9,10).

Description

Die optimale Brennraumgestaltung wie auch das Verdichtungsverhältnis sind für den Wirkungsgrad eines Verbrennungsmotors von entscheidender Bedeutung.The optimal combustion chamber design as well as the compression ratio are for the Efficiency of an internal combustion engine is crucial.

Der Erfindung liegt die Aufgabe zugrunde, auch bei hohen Verdichtungsverhältnissen den Brennraum dem Optimum (kugelförmig) anzunähern. Erfindungsgemäß wird dies durch die Anordnung von zwei Zylindern in einem stumpfen Winkel zueinander gelöst. Diese beiden Zylinder nutzen einen gemeinsamen Zylinderkopf und bilden einen gemeinsamen Brennraum. Die Kolben bewegen sich gegenläufig.The invention has for its object, even at high compression ratios Approach the combustion chamber to the optimum (spherical). According to the invention, this is achieved by the Arranged arrangement of two cylinders at an obtuse angle to each other. These two Cylinders use a common cylinder head and form a common combustion chamber. The pistons move in opposite directions.

Über den gemeinsamen Zylinderkopf wird der Kraftstoff eingebracht und das Gemisch gezündet. Die in diesem Bereich angeordneten Ventile werden ebenfalls von beiden Zylindern gemeinsam genutzt.The fuel and the mixture are introduced via the common cylinder head ignited. The valves arranged in this area are also from both cylinders shared.

Eine Veränderung des Verdichtungsverhältnisses ist durch eine Verschiebung der Kurbelwellen möglich.A change in the compression ratio is due to a shift in the Crankshafts possible.
