Petrovic, P. (Industrija Motora Rakovica, Beograd (Yugoslavia))
A part of research results concerning the process of the Diesel engine structural noise generation is presented in the article. The very process of the internal combustion engine functioning initiates the energy creation in its parts which, then, excitate their own modal oscillations of particular components and through their surfaces the sound is emitted into the environment. The researches are done by the author's own method for the application of sound intensity and experimental modal analysis. The results relating to the engine block and the single-part engine oil sump are presented.
