Abstract

Die Erfindung betrifft einen Verbrennungsmotor (2) eines handgeführten Arbeitsgerätes (1) sowie ein handgeführtes Arbeitsgerät mit einem solchen Verbrennungsmotor (2). Der Verbrennungsmotor (2) weist ein Kurbelgehäuse (4), eine im Kurbelgehäuse (4) um eine Drehachse (D) drehbar gelagerte Kurbelwelle (5), einen Brennraum (6) und mindestens einen vom Kurbelgehäuse (4) zum Brennraum (6) führenden Überströmkanal (7) auf. Der Überströmkanal (7) mündet mittels eines Eingangsfensters (8) in das Kurbelgehäuse (4). Das Kurbelgehäuse (4) weist eine in einer Umfangsrichtung (U) verlaufende Umfangswand (9) auf, wobei die Umfangswand (9) mit mindestens einer Kraftstoffrückhalteeinrichtung (10) versehen ist. Eine Radialrichtung (R) verläuft ausgehend von der Drehachse (D) durch die Kraftstoffrückhalteeinrichtung (10). Die Kraftstoffrückhalteeinrichtung (10) weist eine Erstreckung in der Radialrichtung (R) und in der Umfangsrichtung (U) auf. Die Kraftstoffrückhalteeinrichtung (10) weist bezogen auf die Radialrichtung (R) einen in der Umfangsrichtung (U) unsymmetrischen Querschnitt auf.
