EXHAUST SILENCER FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

Abstract RU 2046965 C1

FIELD: engine engineering. SUBSTANCE: silencer has chamber defined by housing 1 and face walls 2 and 3 and perforated scatter of sound energy. Inlet branch pipe 4 and outlet branch pipe 5 are secured to the walls. The inner dynamic cross-sections 6 and 7 of the branch pipes are arranged in the noddle zones of low natural resonance modes of gas space oscillation inside the chamber. The scatter is positioned at the same distances from cross- sections 6 and 7. The scatter is constructed as two perforated baffles 8 and 9 which define a given space between them. EFFECT: enhanced reliability. 4 cl, 9 dwg
