Abstract

Kolben (1) eines Verbrennungsmotors, vorzugsweise eine Fahrzeugmotors, dadurch gekennzeichnet, dass im Kolbenboden mehrere Mulden (2) eingelassen sind.Piston (1) of an internal combustion engine, preferably a vehicle engine, characterized in that several depressions (2) are embedded in the piston head.

Description

Die Erfindung betrifft einen Kolben eines Verbrennungsmotors, vorzugsweise eines Fahrzeugmotors.The invention relates to a piston of an internal combustion engine, preferably a vehicle engine.

Erfindungsgemäß sind im Kolbenboden mehrere Mulden eingelassen. Hierdurch entstehen im Kolbenboden beim Verbrennungstakt mehrere Brennräume, so dass das Frischgas besser, durchgängiger verbrennt. Mithin ist die Kraftausbeute größer und der Kraftstoffverbrauch ebenso geringer wie auch der Schadstoffgehalt.According to the invention a plurality of wells are recessed in the piston head. This results in the piston crown during the combustion cycle several combustion chambers, so that the fresh gas burns better, more consistently. Thus, the power output is greater and the fuel consumption as well as the pollutant content.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt, worin der Kolben 1 im Kolbenboden Mulden 2 aufweist.An embodiment of the invention is illustrated in the drawings, wherein the piston 1 in the piston bottom hollows 2 having.
