APPLICATION OF VIBROACOUSTICS METHODS FOR IC ENGINE DIAGNOSTICS

Abstract

Sound and vibration signal of IC engine often give much dynamic information of mechanical system condition. The energy state of the pistons and the connecting rods is determined by the mean angular speed and the angular positions of the crankshaft. Changes in the pressure in cylinder caused by compression faults or misfire will affect directly the instantaneous angular speed of the crankshaft and vibration energy. In this paper engine faults and its influence on vibration of engine block and head is presented.
