| Abstract: | With the computer simulation of exhaust mufflers and IC engines, the influence of mufflers on engine performance as well as exhaust noise can be predicted. For engineering purpose, authors proposed simple muffler design criteria based on experiments and combined with muffler simulation program. A new exhaust muffler was designed with the help of computer aided analysis. Experiments show that the comprehensive performance of the muffler has been improved. |
