Abstract

PURPOSE: To obtain the subject device of simple structure enabling the reduction of the generated noise covering a wide range of frequency effectively in the apparatus which reduces low frequency pulsating noise having the engine explosion cycles and their double and the tripple harmonics.
CONSTITUTION: Second and first expansion chambers 3 and 2, and a resonance chamber 4 are partitioned from the left side longitudinally in a silencing apparatus body 1, and an exhaust tube 5 is so provided through the second expansion chamber 3 as to open in the first expansion chamber 2. A resonance tube 6 communicating with the resonance chamber 4 is disposed along the extension line of the tube 5 to open with the first expansion chamber 2 at predetermined interval from the end of the tube 5. Further, the first and second expansion chambers 2 and 3 mutually communicate with each other through an exhaust gas introduction tube 7 having the same diameter as that of the tube 6, and the second expansion chamber 3 communicates with the atmosphere through an exhaust outlet tube 8 passed through the first expansion chamber 2 and the resonance chamber 4. The side end of the resonance chamber 4 of the tube 6 is so obliquely cut as to pass the point disposed toward the expansion chamber 2.
