FISHBONE STANDARDISED SILENCERS FOR (INTERNAL) COMBUSTION ENGINES

摘要

This patent application is for a new silencer design with the following features: free (exhaust) gas flow through, which means close to zero back pressure, or head loss; superior acoustic performance, especially in the high- and mid frequency ranges; increased engine net performance and efficiency; identical accoustical performance throughout its service life; simple, light, modular configuration, prone to: cheap industrial automatic production; reusing (cartridge type), and/or recycling, thus avoiding pollutant waste; standardising and uniformising of silencers throughout the (automotive) industry; constructed from the suitable material, can provide a really unlimited lifetime. Although this design is particularly suitable for (internal) combustion engine exhaust and induction mufflers, it can be applied advantageously to other silencers in- and outside the industry and, in general, our living environment (gas flow duct silencers, airco-, venting-, etc...).
