<p>An apparatus for removing exhaust gas pressure and preventing backflow of exhaust gas is disclosed. The apparatus of the present invention includes a mounting pipe (100), which is fitted over the end of an exhaust gas pipe of an internal combustion engine and has therein backflow gas guide holes (102) at positions adjacent to the exhaust gas pipe, and a secondary exhaust gas pipe (110), which surrounds the mounting pipe. In the apparatus, a backflow passage (120) is defined between the mounting pipe and the secondary exhaust gas pipe, so that a backf lowing portion of exhaust gas, which is discharged from the mounting pipe, is drawn into the backflow passage and is guided into the mounting pipe through the backflow gas guide holes, and the guided backflow gas is discharged outside again. Therefore, the present invention prevents backflow gas from being drawn into the exhaust gas pipe, thus enhancing the performance of the internal combustion engine.</p> |
