Abstract

Die Erfindung betrifft einen Verbrennungsmotor mit einer Ölversorgungseinrichtung (9) zum Schmieren eines Zylinders (2) und/oder zum Kühlen eines Kolbens (3), wobei die Ölversorgungseinrichtung (9) so ausgebildet ist, dass eine Schmierung des Zylinders (2) ständig erfolgt, während die Kühlung des Kolbens (3) zuschaltbar ist, und/oder dass die Schmierung des Zylinders bereits bei einem geringeren Öldruck erfolgt, bei welchem noch keine Kühlung des Kolbens stattfindet.The invention relates to an internal combustion engine with an oil supply device (9) for lubricating a cylinder (2) and / or for cooling a piston (3), wherein the oil supply device (9) is designed so that lubrication of the cylinder (2) is constant, while the cooling of the piston (3) is switchable, and / or that the lubrication of the cylinder already takes place at a lower oil pressure at which still no cooling of the piston takes place.
