G12V190 Type Diesel Engine Exhaust Muffler Design Based on Transfer Matrix Method


Article Preview

In this paper the diesel engine exhaust noise in petroleum well workplaces has been measured, the peak values scatters mainly in the low-frequency range, and the top value has reached 123dB. Based on transfer matrix method, this paper analyzes six kinds of silencing elements and establishes optimizing calculation procedure for diesel engine exhaust muffler. According to optimizing calculation procedure and exhaust noise frequency spectrum characteristic of diesel engine, we have designed a new large amount resistance muffler for G12V190 type diesel engine. After petroleum well scene experiment, the insertion loss of exhaust muffler has reached 33dB.
