Computational simulation demonstrates a 17 dB exhaust noise reduction in a two-stroke piston engine, indicating effective acoustic silencing with minimal power loss.
This study presents a computational method for reducing exhaust noise in a two-stroke piston engine. The exhaust system was analyzed using the ALLBEA software package, and its optimization was performed using the ALLBEA NOISE program. A comparison of the calculated engine performance with the optimized silencer and the stock exhaust system demonstrated a 17 dB reduction in sound pressure level at the exhaust outlet, with only a minor power loss (less than 3%) at the shaft speed of 5500 rpm.
