Resonance dampener
SPC
''Edem" has elaborated a new type dampener for automobiles. It is
characterized as a resonance dampener. In a new dampener the interaction
of reflected sound waves with the main spectrum of sound waves, produced
by an engine at pushing out exhausted gases, is taken into account.
new Dampener
The peculiarity of a new dampener consists in its having no bafflers or
interleaves. It represents some sequentially welded tubes of different
length and diameter.
The exhaust gases of an engine come into the first camera of the dampener
through the entrance tube. They widen and loose a part of their kinetic
and acoustic energy. Reflected from a butt-end side, a sound wave eliminates
the noise of discrete exhausted gases. Thus, it reduces the level of noise
to the degree provided by existing dampeners.
Existing Dampener
The advantage of this dampener is that it needs little material, little
efforts to produce it, it has a long term of work, equal to the term of
work of an automobile, little aerodynamic resistance. All these factors
contribute to increasing of the efficiency of an automobile engine, decreasing
of temperature on the surface of the dampener.
The proposed dampener may be used as a main or intermediate resonance
dampener.
