| Abstract: | An experimental equipment for the performance study of mufflers is developed in this paper. The acoustics performances of the mufflers of internal combustion engines with airflow or hot airflow can be studied on this equipment, which presents the basic condition for the analysis and study of mufflers' acoustic performances. The experimental results show that a steady airflow can be set up in the test pipes, the airflow can be heated to the set temperature, and the acoustic conditional in the mufflers of internal combustion engines can be simulated properly. |
