Abstract: An internal combustion engine includes a cylinder defining a combustion chamber enclosed by a cylinder wall, a piston that is arranged inside the combustion chamber and moveable in a reciprocating motion away from and towards a crankshaft, and at least one first scraper ring defining an oil scraper ring that is arranged between the piston and the cylinder wall and configured to scrape oil off from the cylinder wall when the piston moves towards the crankshaft. The internal combustion engine further includes at least one second scraper ring defining a condensation fluid scraper ring that is arranged between the piston and the cylinder wall and configured to scrape a condensation fluid off from the cylinder wall when the piston moves away from the crankshaft.
