Abstract: The invention relates to an internal combustion engine, comprising an intake path, a crankcase, an exhaust gas path and a crankcase ventilation means, wherein the crankcase ventilation means is open, closed or separate. The internal combustion engine according to the invention comprises an intake path, a crankcase, an exhaust gas path and an open crankcase ventilation means, wherein the open crankcase ventilation means comprises a first line and a second line, wherein the first line is designed to connect the exhaust gas path to the crankcase in order to guide exhaust gas out of the exhaust gas path to the crankcase, and wherein the second line is designed to connect the crankcase to the exhaust gas path in order to discharge exhaust gas and leakage gases located in the crankcase from the crankcase and to feed them to the exhaust gas path.

Abstract: The invention relates to a parallel crank drive (10), particularly for an internal combustion engine (11) having variable compression ratio, having: a first and a second clutch body (20, 21) that can each be connected to a first or second shaft (14, 19); —at least one clutch element (22) rotatably supported on both clutch bodies; —a housing (23) encompassing the clutch bodies and clutch elements. The invention further relates to an internal combustion engine having variable compression ratio, having: a pivotally supported crankshaft (14); —drive shaft (19); —parallel crank drive (10) between the crankshaft and drive shaft; —a housing (23) encompassing the parallel crank drive. The invention further relates to a manual transmission, particularly for an internal combustion engine (11) having variable compression ratio, having: an input shaft (19) that can be connected to a pivotally supported crankshaft (14); the parallel crank drive (10) between the crankshaft and input shaft.

Abstract: A four-cylinder, reciprocating piston-machine includes a crankshaft having a rotary axis; a center bearing supporting the crankshaft; two outer bearings flanking the center bearing and supporting the crankshaft; and first, second, third and fourth torsion springs extending parallel to the crankshaft axis. The first and second torsion springs are parallel to and facing a first side of a reference plane containing the crankshaft axis, while the third and fourth torsion springs are parallel to and facing a second side of the reference plane. First, second, third and fourth elongated balancing masses are secured to and extending unidirectionally from respective first, second, third and fourth torsion springs toward the crankshaft in a perpendicular orientation to the crankshaft axis. The first and second balancing masses are situated at the outer bearings, while the third and fourth balancing masses are situated at the center bearing.

Abstract: A reciprocating piston engine includes a housing; a cylinder disposed in the housing; a piston guided for reciprocation within the cylinder; a crankshaft connected to the piston for effecting a guided reciprocation thereof within the cylinder; at least two camplates connected to the crankshaft such that they rotate together with the crankshaft, each camplate defining a control contour thereon; two balancing masses operatively coupled to the camplates such that the camplates are effective for actuating respective ones of the balancing masses, each balancing mass comprising a pivoting arm; and coupling means connecting the balancing masses to one another thereby effecting a forced reciprocation thereof as a function of a rotation of the crankshaft.

Abstract: A reciprocating piston engine, in particular an internal combustion engine with at least one cylinder in which a piston connected with a crankshaft is driven so it can move back and forth. The crankshaft (1) is connected with at least one cam disk turning with it. The cam disc has a control profile which acts as an actuator on at least one additional unit, in particular a compensating weight.
