Abstract

Ein Freikolbenmotor (1) weist mindestens einen Zylinder (2) auf, in dem mindestens ein Kolben (3) verschiebbar geführt ist. Der Zylinder weist mindestens einen Verdichtungsraum (29) zum Verdichten eines Arbeitsgases und mindestens einen Brennraum (30) zum Verbrennen des Arbeitsgases auf. Zur Erzielung eines hohen chemischen und thermischen Wirkungsgrades weisen der Brennraum (30) und der Verdichtungsraum (29) die gleiche Außenkontur auf. Sie sind voneinander durch den Kolben (3) trennbar. Ein Überströmkanal (28) kann den Verdichtungsraum (29) mit dem Brennraum (30) verbinden. Auf diese Weise ergibt sich ein nicht zerklüfteter Brennraum (30), der eine vollständige Verbrennung des Arbeitsgases und geringe thermische Verluste zur Folge hat.

A free-piston engine (1) has at least one cylinder (2), in which at least one piston (3) is displaceably guided. The cylinder has at least one compression chamber (29) for compressing a working gas and at least one combustion chamber (30) for combusting the working gas. To achieve a high chemical and thermal efficiency of the combustion chamber (30) and the compression chamber (29) on the same outer contour. They are separable from each other by the piston (3). An overflow channel (28) can connect the compression chamber (29) with the combustion chamber (30). In this way results in a non-fissured combustion chamber (30), which has a complete combustion of the working gas and low thermal losses result.
