ABSTRACT:
The arrangement for determining rotation angle of two rotating parts in an internal combustion engine includes a first rotating part having a protruding member extending laterally from the first rotating part, the first rotating part being connected with a crankshaft of the internal combustion engine; a second rotating part having a protruding element extending laterally, therefrom the second rotating part being connected to a camshaft of the internal combustion engine and the second rotating part being positioned adjacent to the first rotating part; a pickup device for generating a first output signal when the protruding member passes by the pickup device during rotation of the rotating parts and for generating a second output signal when the protruding element passes by the pickup device during rotation of the rotating parts; and a signal processing device for receiving the first and second output signals from the pickup device, for determining a time interval between one of the first and one of the second output signals and for calculating an angular displacement between the first and second rotating part from the time interval. The arrangement includes only one pickup device for generating both first and second output signals and the protruding member and protruding element are shaped and positioned so that each of the first output signals and the second output signals is generated by the single pickup device and the first and second output signals are different and distinguishable from each other.
