Embodiment Construction

[0062] The present application will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0063] figure 1 is a schematic front view of an exhaust muffler device according to an embodiment of the present application. The exhaust muffler generally includes an exhaust pipe 1 and a rear muffler 3 . Wherein, the exhaust pipe 1 is used to collect exhaust gas from an automobile engine. The rear muffler 3 may generally include a bifurcated connecting pipe 3.1, and a left muffler cylinder 3.2 and a right muffler cylinder 3.3 arranged mirror-symmetrically. Among them, the bifurcated connecting pipe 3.1 has a main port 3.11, a branch port 3.12 and a branch port 3.13, the main port 3.11 is welded to the exhaust pipe 1, and is used for exhaust gas to enter the rear muffler 3 for exhaust silencer treatme...

Abstract

The application discloses an exhaust muffler device and an automobile. The exhaust muffler device includes an exhaust pipe for collecting exhaust gas; the rear muffler includes a bifurcated connecting pipe, a left muffler cylinder and a right muffler cylinder arranged symmetrically in mirror images, and the bifurcated connecting pipe has a main port, a branch port and a branch port. port`, the main port is connected to the exhaust pipe for the exhaust gas to enter the rear muffler, the branch port is connected to the left muffler cylinder, and the branch port` is connected to the right muffler cylinder, so that the exhaust gas entering the rear muffler can be exhausted on both sides . After this technical solution, by setting the bifurcated connecting pipe, the bifurcated connecting pipe is connected with the exhaust pipe, the left muffler cylinder, and the right muffler cylinder. And branch ports `separate flow and the left muffler cylinder and right muffler cylinder respectively connected to carry out exhaust muffler treatment, realize bilateral exhaust muffler treatment, increase muffler volume difficult to meet the demand of large-displacement engine.

Description

technical field [0001] The invention relates to the technical field of exhaust mufflers, in particular to exhaust mufflers and automobiles. Background technique [0002] The exhaust muffler is an indispensable device in the car. The exhaust muffler is connected to the exhaust end of the engine. Its main function is to discharge the engine exhaust and reduce noise. The exhaust muffler extends from the front of the engine compartment to the rear of the vehicle. The total length of the device is close to the length of the entire vehicle, and its boundary covers many parts under the chassis. Exhaust silencing devices in the prior art are unilateral and single-outlet exhaust silencing, and the silencing volume is difficult to meet the needs of large-displacement engines. Contents of the invention [0003] It is an object of the present application to overcome the above-mentioned problems or to at least partially solve or alleviate the above-mentioned problems. [0004] To thi...
