| 英文摘要 | This study represents the influence on exhaust performance by active muffler valve spring. The main experimental parameters were engine speeds and torsion coil spring constants in the active muffler. When the muffler valve spring has a low spring constant of k=0.75, the sound pressure level was low at the region of engine speed 2000 to 2500 r/min, and the velocity of exhaust gas was high at spring constant k=0.75. When the engine speed was under 1500 r/min, the mean concentration of CO was high in case without muffler valve. When the engine speed in the range of 1600 to 2600 r/min with spring constant k=0.75, the mean HC concentration showed the lowest value. Without muffler valve, the temperature in the muffler was higher than the case with muffler valve. This research represented that the performance of the active muffler valve spring constant k=0.75 was higher than that without muffler valve and valve spring constant k=0.70. Among the three cases of experimental condition, with a spring constant k=0.75, 0.70 and without muffler valve, the exhaust performance was high in case active muffler valve spring constant k=0.70. |
