ABSTRACT:
An apparatus for controlling valve performance in an engine is disclosed. A first detection blade helically extends on a camshaft. A pair of second detection blades are located on the camshaft and extend axially on the camshaft. An electromagnetic pickup is arranged to face the camshaft. The pickup produces a pulse in response to one of the blades passing by the pickup when the camshaft rotates. ECU computes the axial position of the camshaft based on the change in the time period from the pulse corresponding to the second blade to the pulse corresponding to the first blade.
