Internal ignition motor is a noteworthy wellspring of commotion contamination. Fumes commotion lessening from motors is a vital
issue. Suppressors are utilized to diminish this fumes commotion. Configuration of the suppressor ought to give the best commotion
diminishment and offer ideal backpressure for the motor. In this paper the Experimental and reproduction results for altered suppressor are
exhibited. The standard suppressor with various change are displayed in Autodesk Inventor programming and tried for acoustical execution in
COMSOL a reproducing programming. Clamor estimation for various suppressor alterations are completed tentatively utilizing Fast Fourier
Transform. Relatively changed intelligent suppressor with astounds demonstrates decrease in clamor level and least fuel utilization.
