摘要： An arrangement may include one of a cylinder liner or a cylinder bore formed in a crankcase of an internal combustion engine, a piston having a peripheral top land and being accommodated in the cylinder liner or cylinder bore, and an annular insert accommodated in the cylinder liner or cylinder bore and extending axially parallel to the piston top land. The cylinder liner or cylinder bore may have a radially inwardly-directed shoulder at an upper free end of the cylinder liner or cylinder bore. The annular insert may have along an upper peripheral free edge of the annular insert, distributed around a circumference of the annular insert, at least two beads or embossments located opposite one another and resting on the radially inwardly-directed shoulder.

摘要： A drive system may include an internal combustion engine and an expander operated via a working medium. A force transmission device may be disposed between a crankcase and the expander. A first seal may be disposed between the expander and the force transmission device and/or a second seal may be disposed between the force transmission device and the crankcase. A crankcase ventilation line may lead from the crankcase into an intake pipe of the internal combustion engine. An air mass sensor may be disposed in the intake pipe. An engine control unit may be in communication with the air mass sensor, the expander, and the internal combustion engine and may be configured to detect a power of the internal combustion engine and an air mass flow of the air mass sensor and may switch off the expander if a power suddenly rises with the air mass flow remaining constant.

摘要： A connecting rod for converting a linear motion of a piston into a rotational motion of a crankshaft may include a small connecting eye for connecting the connecting rod in a rotatable manner to a pin of the piston and a large connecting rod eye for connecting the connecting rod in a rotatable manner to the crankshaft. The connecting rod may include at least one eccentric lubricating groove disposed in at least one o an inner face of the large connecting rod eye, an inner ace of the small connecting rod eye, and a bearing bush arranged in the small connecting rod eye. The at least one groove may have an axis inclined with respect to an axis of at least one of the respective small connecting rod eye, large connecting rod eye, and bearing bush.

摘要： A method for machining an annular groove, which is circumferential in a circumferential direction, on a cylindrical outer circumferential surface of a component is disclosed. The annular groove may have two lateral groove walls and a groove base transitioning into the two lateral groove walls in a respective transition region of two transition regions. The method may include contacting the groove base with a free end of a tool. The free end may include two lateral convex regions and a withdrawn region arranged therebetween. The method may further include reinforcing the annular groove such that the two transition regions of the annular groove are reinforced more strongly than a centre region of the groove base.
