Engine speed measurements, commonly based on period measurements of signals generated by toothed wheel, mounted on the crankshaft, are prone to errors due to a mounting issues or wheel\\\'s geometrical imperfections. Although this fact is widely accepted as a usual problem in a large series engine production it is uncommon fact that similar errors can be produced by using much more sophisticated measuring devices like high resolution angular encoders which are exclusively used in lab measurements. This paper presents hidden potentials of a front end mounted encoder to generate relatively large angular speed and acceleration errors due to a minor mounting errors or geometrical incompatibility.
