Abstract

Sistema de escape para modificar la sonoridad de motor endotérmico, que comunica el interior de alguno de los elementos que lo componen, por el que circulan los gases de escape, con el aire exterior a este sistema. En una de sus variantes comprende como mínimo: Un conducto auxiliar (6) que recorre: El interior del silenciador (1) y del catalizador (12), de existir estos, el interior del conducto de escape (2), el interior del colector de escape (3), y el interior de la culata ( 4) del motor, estando todos estos elementos interconectados de manera que los gases de escape captados por el orificio (7) del conducto auxiliar ( 6) transiten, pasando por el interior de cada uno de ellos, desde la culata (4) hasta el orificio de salida (9) del conducto (6), hacia el aire exterior. Sistema de escape simple que modifica la sonoridad del motor endotérmico para singularizarlo.Exhaust system to modify the loudness of the endothermic engine, which communicates the interior of some of the elements that compose it, through which the exhaust gases circulate, with the air outside this system. In one of its variants it comprises at least: An auxiliary duct (6) that runs: The interior of the silencer (1) and the catalyst (12), if these exist, the interior of the exhaust duct (2), the interior of the manifold exhaust (3), and the inside of the cylinder head (4) of the engine, all these elements being interconnected so that the exhaust gases captured by the hole (7) of the auxiliary duct (6) pass through the interior of each of them, from the cylinder head (4) to the outlet orifice (9) of the duct (6), towards the outside air. Simple exhaust system that modifies the loudness of the endothermic engine to single out it.
