| Abstract: | In the paper,the muffler with catalyst is designed for small diesel engines,which takes foam ceramic as the filtration material and applies the catalytic converter with the activated carbon fibers（ACF）.Compared with the original one tested under rated condition,the developed muffler with catalyst can reduce the noise more than 4dB（A） and the content of the harmful emission NO by 48.1%.Moreover,HC,CO and smoke intensity are decreased to some extent too,which achieves a good effect.It supplies an efficient approach to the performance improvement of small diesel engines. |
