Embodiment Construction

[0012] The present invention will be further explained below in conjunction with the drawings and embodiments:

[0013] participate figure 1 The muffler is divided into double layers. After the exhaust gas enters the muffler through the double introduction pipes (3) (6), it enters the upper cavity. The upper cavity is divided into two cavities. The upper cavity (4) is a steel wire blanket and glass wool to form a resistive muffler. The upper two cavities (2) are plug-in structures to constitute a resistant muffler, which contains a catalyst (1). After the exhaust gas is purified by the catalyst, it reaches the lower layer. The two cavities have an internal cannula structure. The waste gas enters the lower third cavity (9) through the lower second cavity cannula (10) from the lower second cavity (11), and flows back to the lower second cavity through a flanged hole, and then passes through a tail row The air pipe (8) is exhausted, and the exhaust valve (7) is installed on the tail...

Abstract

The invention discloses a muffler for large-displacement luxury motorcycles. The muffler is in a two-layer five-cavity structure divided into two upper cavities and three lower cavities by a partition. The muffler comprises double intake pipes, the partition, a housing, an insert pipe, a tail pipe, an exhaust valve and the like. The muffler allows noise under both high and low frequencies to be suppressed finely. The application of exhaust valve technology coordinates noise reduction and engine power. The tail pipe is provided with the exhaust valve which is manually turned on or off by a racing driver. The muffler has the advantages that the three expansion cavities, the two glass-wool-filled cavities and the insert pipe coordinate to reduce noise, and acoustic energy is reduced greatly; the cavities have large volume, and the muffler is applicable to large-displacement luxury motorcycles; the exhaust valve mounted on the tail pipe is manually controlled by the racing driver so that noise reduction adjustment and engine power adjustment are balanced.

Description

Technical field [0001] The invention relates to a muffler device, in particular to a muffler for a large displacement luxury motorcycle. Background technique [0002] Aiming at the high-end motorcycle muffler market, a double-layer five-chamber muffler is designed, which uses a variety of muffler technologies to achieve fine muffler with full suppression of high and low frequencies, and adopts exhaust valve technology. Motor vehicle exhaust mufflers mainly work with several Baidu's high-temperature high-speed pulsating airflow, therefore, the aerodynamic performance of the muffler is another important index to evaluate the quality of the muffler, it directly affects the performance of the engine, and there is also the problem of matching with the engine. If the resistance of the muffler is too large, the power loss of the engine will be too large, which will affect the power and fuel economy of the motor vehicle. Large muffler volume and low power loss are the two main parameters...
