MUFFLER FOR A VEHICLE USING LEADED FUEL, CAPABLE OF REDUCING HIGH-FREQUENCY NOISE THROUGH A NOISE ABSORBING MEMBER AROUND AN INNER PIPE

摘要

PURPOSE: A muffler for a vehicle using leaded fuel is provided to maximize the interference effect of exhaust gas since the stream of the exhaust gas is divided into more than two parts in the inner pipe through the first and second holes of an entrance pipe. ;CONSTITUTION: A muffler(100) for a vehicle using leaded fuel comprises a case(10), an inner pipe(30), a noise absorbing member(50), an entrance pipe(70) and an exit pipe(90). The inner pipe is arranged in the case. The noise absorbing member is filled between the case and the inner pipe. The entrance pipe is connected to the case and one end of the inner pipe. The entrance pipe is arranged in the inner pipe. The exit pipe is connected to the case and the other end of the inner pipe. The exit pipe is arranged to be separated from the entrance pipe in the inner pipe. The entrance pipe comprises a plug(73) and a plurality of second holes(72). The plug is coupled to the inner end of the inner pipe with a first hole(71). The second holes are formed along the circumferential surface of the entrance pipe.;COPYRIGHT KIPO 2011
