| Abstract;For the 2005 Model year LEGEND, a compact lightweight muffler valve with new construction was developed for the variable flow rate muffler. A conventional muffler valve rotates about a shaft. A load is applied to the rotating shaft by a coil spring. For this reason many parts are required for the valve to open and close. The body of the muffler valve traditionally coveres the entire valve operating range, resulting in the valve being large and heavy. As a method of reducing the number of parts and the weight of the valve, this development employed the mechanism of the reed valve. A reed valve is used in 2-cycle motorcycle engines to control the intake air volume at the intake port. The addition of a support plate to the reed valve structure was investigated to suppress valve vibration and to apply a pre-load. The number of parts in the newly developed muffler valve was reduced from 13 parts in the conventional valve to four parts. Both the weight and volume were reduced to about 1/10. This enabled the cost to be reduced to about 1/7 of a traditional exhaust valve. (author abst.) |
