| Summary: | The paper presents the procedure and the
experimental set-up for some functional parameters
the determination of the noise level, the pressure drop and the
temperatures through investigating three different
manufacturing solutions for mufflers. An algorithm and a
the dedicated method has been proposed in order to emphasize
more direct the mufflers influence on the engines performances.
The procedure equally includes particular cycles of the engine
and it is highlighted the relation between the engine operating
conditions and the functional parameters of the automotive
mufflers. The experimental results emphasize the corroboration
between these parameters and contribute to the improvement of
the muffler fabrication and design since it is a complex function
that affects noise characteristics, emission and fuel efficiency of
engine. It was designed a measurement chain for the noise level
evaluation of the mufflers. It was also created a measurement
chain for the pressure – drop evaluation and temperature
distribution on the external surface of the mufflers. |
