PRESENTATION OF THE SM EVO® RANGE • ur silencers are designed to reduce the noise generated by the exhaust gases of internal combustion O engines. • Our new generation of EVO® silencers have been optimised by our aero-acoustic engineers. Using the latest generation of finite element software, this optimisation has enabled us to numerically validate the very complex behavior of aero-acoustic phenomena in our silencers. Our numerical models have been qualified by dynamic tests in our laboratory and on an industrial site. • Our SM EVO® silencers are fully welded in carbon steel, with internal...
