Abstract

Eine Ölversorgung für einen Verbrennungsmotor weist eine Ölzuführein­richtung zum Zuführen von Öl zu einem in einem Zylinder (9) hin- und her­beweglichen Kolben (8) auf. Die Ölzuführeinrichtung ist derart ausgebildet, dass wenigstens zu einem Zeitpunkt, zu dem sich der Kolben (8) im Bereich seines unteren Totpunkts befindet, durch die Ölzuführeinrichtung Öl direkt in einen Bereich unterhalb des Kolbens (8), insbesondere unterhalb seines Kolbenbodens (12) und innerhalb seines Kolbenhemds (13) ausbringbar ist. Dazu weist die Ölzuführeinrichtung wenigstens ein Rohrelement (16) auf, das in einen Bereich unterhalb des Kolbenbodens (8) ragt. Das Rohrelement (16) sollte möglichst in der Nähe eines Kolbenbolzens (6) enden, wenn sich der Kolben (8) in seinem unteren Totpunkt befindet. Dadurch ist eine ge­zielte Ölschmierung des mechanisch und thermisch hoch belasteten Kol­benbolzens (6) gewährleistet. Außerdem ist es durch die Ölversorgung mög­lich, Überströmkanäle (15a) eines Zweitaktmotors mit Öl zu versorgen, um einer Verkokungstendenz entgegenzuwirken.
