MUFFLER FOR VEHICLES IN ORDER TO PERFORM SPORTY BOOMING SOUND

摘要

PURPOSE: A muffler of a vehicle for implementing sporty exhaust sound quality is provided to reduce exhaust booming in a low rpm range while intensifying the exhaust booming in a high rpm range by optimizing the location of a baffle plate and of a chamber. CONSTITUTION: A muffler of a vehicle for implementing sporty exhaust sound quality includes a first to a fourth baffle plate(31-34), a first to a fifth chamber(C1-C5), an intake tube(80), a first exhaust tube(40), a second exhaust tube(50), a first middle tube(60), and a second middle tube(70). The first to fourth baffle plates are partitioned by the first to fifth chambers. The first exhaust tube passes through a side panel(20) of one side, the first baffle plate, and the second baffle plate; while an inlet is positioned on the third baffle plate, and the outlet is positioned on the outside of the side wall of one side. The second exhaust tube passes through the third baffle plate, the second baffle plate and a side panel(21) of the other side; while an inlet is positioned on the third baffle plate, and the outlet is positioned on the outside of the side wall of the other side. The first middle tube forms multiple through holes in a section of a tube body which is positioned inside the third chamber among the sections of the tube body. The second middle tube forms multiple through holes in a section of a tube body which is positioned inside the third chamber among the sections of the tube body.
