Exhaust system for vehicle

Abstract

An exhaust system comprises a pipe disposed in a vehicle, and a resonator and a muffler, both of which are combined together and have inner chambers communicating with each other and commonly disposed on the pipe. The exhaust system further has a support unit capable of restricting vibration amplitudes of the resonator and the muffler relative to the vehicle. Thus, the exhaust system effectively solves the problem that a welding portion of the conventional exhaust system tends to break, and prevents the combustion and horse power from encountering the nonessential influence.

Description

BACKGROUND OF THE INVENTION(1) Field of the Invention[0001]The invention relates to the exhaust field for a vehicle, and more particularly to an exhaust system applicable to the vehicle.(2) Description of the Prior Art[0002]The vehicle is one of traffic tools. A good gas supply system needs to be used to provide the exploding combustion and horse power. The gas supply system is divided into the intake and the exhaust. No smooth intake can be provided when no smooth exhaust back pressure occurs.[0003]Next, the basic principle of an exhaust system 10 will be introduced with reference to FIG. 7. An exhaust manifold 12 (also referred to as an exhaust head section), a catalytic converter 14, a resonator 16 and a muffler 18 are disposed on a pipe 20.[0004]The exhaust manifold 12 has a diverging end and a converging end. The diverging end is connected to an engine (not shown), and the converging end is connected to the pipe 20. When the cylinder of the engine performs an intake operation a...

AI Technical Summary

Benefits of technology

The exhaust system for a vehicle described in this patent aims to reduce the vibration of the resonator and muffler, which can help prevent damage to the vehicle's engine and cause problems with its performance. A support structure is used to limit the movement of these components, and this can be effective in preventing the connection points between the resonator and muffler from breaking. This solution also helps prevent the exhaust gas from affecting the vehicle's performance.

Problems solved by technology

No smooth intake can be provided when no smooth exhaust back pressure occurs.

In FIG. 9, a welding portion 17 is a ring of metal material molten onto the outer surfaces of the input section 13 and the open end 11, and tends to break due to the vibrations of the resonator 16 and the muffler 18 so that the muffler 18 falls off the vehicle, When a tail tube is mounted behind the muffler 18, both of which commonly fall off, Thus, the exhaust system has no smooth exhaust back pressure, and the gas supply system does not have the smooth intake anymore, thereby seriously affecting the combustion and horse power.
