|Abstract:||An active exhaust silencer was developed for a reciprocating petrol engine using an oscillating butterfly valve. The active silencer was installed on a Mitsubishi V6 petrol engine loaded by an eddy current dynamometer and was able to withstand exhaust gas temperatures of 500C. Experimental results showed that the oscillating butterfly valve was able to simultaneously attenuate tonal noise at the 1x and 2x cylinder firing frequencies.|
