Abstract

patente de invenção: parte de cano de escape e aparelho de escape para motores de combustão interna. com o intuito de proporcionar uma parte de cano de escape e um aparelho de escape para um motor de combustão interna que pode tornar desnecessário o silenciador usado no aparelho convencional, e tornar pequeno em tamanho um dispositivo de amortecimento sonoro montado na parte do cano de escape enquanto reduz os ruídos de escape, e pode reduzir o peso e os custos de produção do mesmo. uma parte de cano de exaustão (41) é proporcionada em um cano de exaustão (28) para constituir parte do cano de exaustão (28), e tem um membro vazado (42) conectado ao cano de exaustão (28) em um alinhamento axial com o cano de exaustão (28) a ser posicionado dentro de uma área que cobre uma porção de nó em uma distribuição de pressão sonora de uma ressonância de coluna de ar causada no cano de exaustão (28),e um cano curto (43) proporcionado no membro vazado (42) e tendo um comprimento predeterminado parase estender na direção axial do cano de exaustão (28), sendo que o cano curto (43) tem uma extremidade aberta (43a) na extremidade a montante da mesma e uma tremidade fechada é constituída por uma placa inferior(43b) posicionada quase na mesma posição da porção de nó na distribuição de pressão sonora de uma onda imóvel formada pela ressonância de coluna de ar causada no cano de exaustão (28).
