Internal combustion engine i.e. four cylinder reciprocating piston engine, for use in motor vehicle i.e. passenger car, has lever mechanism acting on crank shaft bearing for transmission of torque and for adjusting bearings

Internal combustion engine has cylinder crankcase, variable compression and multiple connecting rods supported at piston, where connecting rods are mounted on crankshaft, and gear is provided for adjusting crankshaft position

Piston combustion engine mounted in motor vehicle, has transmission element having swivel control levers that are mounted on motor case and are supported such that levers arms are coupled with one of eccentric rings

Stroke piston mechanism for use in e.g. petrol engine, has crank shafts that do not protrude radially over maximum outer diameter of tappets, where maximum outer diameter of eccentric tappets is smaller than movement curve

Parallel crank mechanism for use in internal combustion engine to transmit torque from eccentrically stored crankshaft, has discharging unit discharging oil flow coming out from space in axial direction of coupling elements

Reciprocating piston mechanism for use with variable compression ratio, particularly for internal combustion engine of motor vehicle, comprises cylinders, which are arranged in cylinder crankcase, and guides piston

Oil supply system of parallel crank mechanism connected to internal combustion engine, has bearing from which oil is led out through circumferential opening between shaft end and opening in parallel crank mechanism

Valve and internal combustion engine with such a change-over valve

Powertrain for vehicle i.e. passenger car, has drive shaft connecting eccentrically adjustable bearing crankshaft and driven shaft, where clutch of crankshaft is arranged by drive shaft that comprises flange

Internal combustion engine, has sliding fit attached to clutch release sleeve of shifting device, where sleeve is connected with membrane disk of clutch and displaceably guided to crankshaft by sliding fit in direct or indirect manner
