Embodiment
[0019] Mufflers for motorcycle exhaust systems, such as Figure 1-4 shown. Comprising a shell 29, and an air inlet pipe 25 and an air outlet pipe 30 arranged in the inner chamber of the outer shell, two first baffles and a second baffle parallel to each other are successively arranged in the inner chamber of the outer shell 29, and the inner chamber Divided into a first chamber 21, a second chamber 22, a third chamber 23 and a fourth chamber 24, the first partition is provided with a ventilation hole 31 for communicating with two adjacent chambers; The air inlet pipe comprises a straight tube section and a U-shaped tube section, and the inlet end of the straight tube section passes through the front end face of the shell 29 to form the muffler air inlet; the gas outlet end of the straight tube section extends from the muffler inlet to the first chamber 21, and the At least one three-way catalyst is coaxially arranged in the inner cavity. One end of the U-shaped pipe section i...

The invention provides a silencer of an exhaust system of a motorcycle. An inner cavity of a shell is sequentially divided into a first cavity, a second cavity, a third cavity and a fourth cavity; an air outlet end of a straight barrel pipe section of an air inlet pipe extends to the first cavity from an air inlet of the silencer; a three-way catalyst is arranged in an inner cavity of the straight barrel pipe section; a U-shaped pipe section penetrates through the second cavity from the first cavity, and then returns to the first cavity in a penetrating manner; the silencer further comprises a first ventilating pipe and a second ventilating pipe; the first ventilating pipe penetrates through the third cavity from the second cavity and extends into the fourth cavity; the second ventilating pipe penetrates through the fourth cavity from the third cavity; and an air outlet pipe penetrates through the fourth cavity from the third cavity and extends out of an end surface of a rear end of the shell to form an exhaust port of the silencer. Through abrupt change of the cross section and insertion of the cross section of the silencer, waste gases entering the cavities reflect and mutually interfere (rub) to achieve the silencing effect, and through increasing of an air flow path, air flow pressure and speed are reduced to reduce noises.
Description
technical field [0001] The invention relates to the field of motorcycles, in particular to a muffler for a motorcycle exhaust system. Background technique [0002] The intake and exhaust system of a motorcycle includes an intake system and an exhaust system. On the engine, the part that sucks the mixed gas into the engine is called the intake system, and the part that discharges the burned exhaust gas out of the engine is called the exhaust system. The intake system includes air filter, carburetor and intake pipe, etc. After the air is filtered by the air filter, it flows through the carburetor and mixes with gasoline, enters the intake manifold through the intake pipe, and enters the engine through the intake valve to ignite and burn to generate power. [0003] The motorcycle exhaust system includes an engine and a muffler, and the exhaust end of the engine is connected to the muffler. The muffler is a device that allows airflow to pass through and attenuates noise, so t...
