Internal combustion engine with means for condensation fluid removal

A piston for an internal combustion engine, the piston comprising:

• a first groove arranged on an outer circumference of the piston to receive a first scraper ring;
• a second groove arranged on the outer circumference of the piston to receive a second scraper ring, wherein the second groove is arranged closer to a piston crown of the piston than the first groove;
• and
• a drain channel arranged adjacent to the second groove and extending inwardly from the second groove into the piston;
• wherein the drain channel is fluidly connected with a further drain channel extending downwardly out of the piston.

An internal combustion engine, comprising:

• a cylinder defining a combustion chamber enclosed by a cylinder wall;
• a piston comprising a first groove arranged on an outer circumference of the piston to receive a first scraper ring;
• a second groove arranged on the outer circumference of the piston to receive a second scraper ring, wherein the second groove is arranged closer to a piston crown of the piston than the first groove;
• and a drain channel arranged adjacent to the second groove and extending inwardly from the second groove into the piston;
• wherein a first scraper ring is arranged in the first groove and a second scraper ring is arranged in the second groove, and wherein the piston is arranged inside the combustion chamber and moveable in a reciprocating motion away from and towards a crankshaft;
• and
• a fluid-oil separator arranged downstream of the drain channel and configured to separate the scraped off condensation fluid from residual or remaining lubricating oil present therein.
