Abstract: This paper investigates the application of the mechanical impedance method in determining the amplitude-frequency characteristics of parts and assemblies of internal combustion engines. The developed procedures can be applied to reduce vibrations and vibro-acoustic intensity. Analytical and experimental studies are presented to assess the significance of oil contact surfaces on the complex mechanical resistance. The influence of elastic properties of contact link elements in the mechanical system on transient transfer functions are determined by the mechanical impedance method for “piston-rod” and “rod-crankshaft” assemblies. In the range of resonance frequencies, the transient impedance module could increase by 6-8 dB from the effect of oil layers at the inter-element junctions
