Abstract
PURPOSE: To reduce back pressure caused by a division wall by increasing or decreasing the opening area of communication port of the division wall of a muffler according to an operation condition.
CONSTITUTION: An exhaust gas conveying pipe 2 is inserted freely and slidably enabling to rub against the end plate 11 and respective division plates 13W15 for the exhaust gas conveying pipe 2 to allow thermal expansion independently against a shell 1. Then, the exhaust gas conveying pipe 2 secures block plates 7 and 8 disposed in parallel with the division plates 14 and 15. Those block plates 7 and 8 are secured on the thermal expansion side of the exhaust gas conveying pipe 2 against the division walls 14 and 15, the block plates 7 and 8 may be close to or departing from the division plates 14 and 15 by expansion and contracting actions caused by thermal expansion, configuring to close or fully open a part of communication port 16 which is opened for the division walls 14 and 15. This enables the communication port 16 to fully open in high speed and high load condition for improving the output by reducing the back pressure.
