The automobile exhaust system mainly discharges the exhaust gas discharged by the engine, and reduces the exhaust gas pollution and noise. Automobile exhaust system is mainly used for light vehicles, mini vehicles, buses, motorcycles and other motor vehicles.
Automobile exhaust system refers to the system that collects and discharges exhaust gas. It is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tail pipe.
1. During the use of the vehicle, due to the faults of the oil supply system and ignition system, the engine is overheated and backfired, resulting in the sintering and peeling of the carrier of the three-way catalytic converter and the increase of exhaust resistance; 2. Due to the use of fuel or lubricating oil, the catalyst is poisoned, the activity is reduced, and the catalytic conversion efficiency is affected. Sulfur and phosphorus complexes and sediments are generated in the three-way catalyst, which worsens the performance of the vehicle, resulting in the decline of power performance, increase of fuel consumption, deterioration of emissions, etc.
To reduce the noise of the sound source, we should first find out the mechanism and law of the noise generated by the sound source, and then take measures such as improving the design of the machine, adopting advanced technology, reducing the exciting force of the noise, reducing the response of the sound generating parts in the system to the exciting force, and improving the machining and assembly accuracy. Reducing the exciting force includes:
Improve accuracy
Improve the dynamic balance accuracy of rotating parts, lubricate moving parts and reduce resonance friction; Reduce the flow velocity of various air flow noise sources to avoid excessive turbulence; Various measures such as isolation of vibrating parts.
Reducing the response of the sound generating parts to the excitation force in the system means changing the dynamic characteristics of the system and reducing the noise radiation efficiency under the same excitation force. Each sound system has its own natural frequency. If the natural frequency of the system is reduced to less than 1 / 3 of the frequency of the excitation force or much higher than the frequency of the excitation force, the noise radiation efficiency of the system will be clearly reduced.
