Abstract
A device to investigate the flow movement in cylindrical components of reciprocating piston internal combustion engines, which flow movement is generated by a flow-guiding system located, as seen in the flow direction, upstream of the cylindrical component, has at least one rotatable measuring vane in the cylindrical component, the axis of rotation of which intersects the axis of the cylindrical component at an adjustable angle other than 0.degree.. A shaft supporting the measuring vane is connected to a device to evaluate the frequency of rotation and/or the position of the angle of the measuring vane in order to determine one or more parameters of the flow movement in the cylindrical component.
