Vibroacoustic methodes of assessing valve clearance in combustion engines. An analysis of signals in the area of amplitude – point discriminants

Abstract

This article presents results of research referring to applying selected point parameters of vibration signal to assess valve clearance of combustion engines. The authors indicate necessity to apply a complex process to prepare signal of vibration accelerations before making calculations of point parameters characterizing vibroacoustic signal in order to decrease the risk of inaccurate analysis.
