Abstract: An internal combustion engine includes an internal combustion engine interior and a lubricant disposed in the internal combustion engine interior. The lubricant lubricates a component disposed in the internal combustion engine interior and the lubricant is a water-containing lubricant. In an embodiment, the internal combustion engine interior is fluidically connected to an environment surrounding the internal combustion engine by a ventilation device where the ventilation device has a semipermeable membrane which is impermeable to water and water vapor.

Abstract: An external rotor pump has an outer rotor with a sliding surface which is arranged on the outer side thereof, and an opposing body in which the outer rotor is mounted rotatably by way of the sliding surface thereof on an inner guide surface of the opposing body and is in mechanical contact with the inner guide surface. An inner rotor which is mounted such that it can be rotated eccentrically with respect to the outer rotor is provided. The sliding surface or the inner guide surface has a surface structure which has a load-bearing region and a non-load-bearing region which is depressed in contrast with the former.

Abstract: A device for changing a compression ratio of an internal combustion engine is provided. The engine has a crank drive with a crankshaft with at least one crank pin, mounted in a rotationally movable fashion, connected to a connecting rod and a piston arranged in a cylinder of the internal combustion engine. In order to convert rotational movement of the crankshaft into a bidirectional movement of the piston with a defined stroke height, a rotationally movable, externally toothed eccentric for changing the piston stroke height is arranged between the crank pin and an eyelet on the connecting rod. In order to rotate the eccentric, an externally toothed first gearwheel is axially connected in a rotationally fixed fashion to a second gearwheel via a shaft arranged parallel to the crankshaft which is arranged in a meshing fashion on a third gearwheel which can be rotated by an actuating element.

Abstract: An internal combustion engine includes a first injector and a second injector for injecting fuel directly into a combustion chamber in a cylinder in a crank case of the internal combustion engine. The combustion chamber is delimited at one side by a piston which is arranged in the cylinder so as to carry out a stroke and at the other side by a cylinder head. At least one gas exchange inlet valve and a gas exchange outlet valve are provided in the cylinder head for a charge exchange. The first injector is largely oriented in the direction of a cylinder axis, and the second injector is oriented at an angle to the cylinder axis. Maximally 80% of a full-load fuel quantity required by the internal combustion engine for a full load can be introduced into the cylinder using the first injector and maximally 50% using the second injector. The injectors can be configured for smaller fuel flow rates using the internal combustion engine design and operating method, whereby the precision of the injection is improved.
