Abstract: PURPOSE: A muffler for an engine exhaust gas with an external air suction unit is provided to reduce noise flowing into a muffler body by bypassing a part of exhaust gas using a suction unit. CONSTITUTION: A muffler for an engine exhaust gas with an external air suction unit comprises a muffler body(100) and a suction unit. The diameter of the muffler body is bigger than the diameter of a suction pipe(200) and a discharge pipe(400). The suction unit inhales external air into the muffler body. The suction unit comprises suction holes(310), a bypass pipe, and an actuator. The suction holes are installed on the wall of the suction pipe. The bypass pipe bypasses a part of exhaust gas passing through the suction pipe. The actuator is formed around the suction holes and allows the external air and the exhaust gas to flow into the muffler body.

Abstract: A silencer for an engine exhaust system is provided to remarkably reduce noise in an engine by installing a resonator in a ring shape at an opening in the silence. A silencer(100) for an engine exhaust system comprises a body(10) having a cylindrical shape and a plurality of resonators(30) having a ring shape. The silencer is connected to an exhaust gas tube(20) of the engine. The body is formed between the exhaust gas tubes and has larger width than that of the exhaust gas tube. The resonator is formed in the body to block noise introduced into the body. Partition walls are formed in a radial direction at the center of the resonators. The resonator is formed at the inner side of an opening in the body. Exhaust gas and noise are introduced through the opening.
