An internal combustion engine, comprising:

• an internal combustion engine interior;
• a lubricant, wherein the lubricant is disposed in the internal combustion engine interior, wherein the lubricant lubricates a component disposed in the internal combustion engine interior, and wherein the lubricant is a water-containing lubricant;
• and
• a ventilation device, wherein the internal combustion engine interior is fluidically connected to an environment surrounding the internal combustion engine by the ventilation device;
• wherein the ventilation device has a first semipermeable membrane which is impermeable to water and water vapor in a first direction from a first surface of the first semipermeable membrane toward a second surface of the first semipermeable membrane and wherein the first surface of the first semipermeable membrane faces toward the internal combustion engine interior.
