KR200204396Y1 - High power silencer - Google Patents

Abstract

The present invention relates to the internal structure of the silencer (SILENCER) for cars, by improving the internal structure of the silencer widely used to date to reduce the emission resistance of the exhaust gas to improve the output and fuel economy and reduce the noise.

This DYNAMIC muffler is applied to all automobiles and is suitable for the high oil price era. It improves the durability of the muffler and reduces the noise by reducing the internal pressure of the shell by improving the gas flowability inside the silencer.

Description

High Power Silencer {HIGH POWER SILENCER}

In general, the engine generates power when only fuel, air and flame are satisfied. The structure of the car is divided into fuel supply, air supply, and electricity supply. Also, by making exhaust system, exhaust noise and air pollution caused by engine operation are reduced. It is reducing.

To date, much research has been conducted on fuel, air and flames. Exhaust systems also require much research. Explosion noise is generated when the engine is running. Reducing this noise was a common silencer. However, the high power muffler designed can reduce the resistance to the compression stroke of the engine by minimizing the vibration and inflation pressure caused by the shock inside the muffler itself.

Therefore, not only will the output be improved, but also the fuel efficiency will be greatly affected by the environmental pollution prevention.

The present invention is a departure from the conventional silencer structure (a way to give the plate a flat and let the pipe pass between the plates and make a hole in the pipe to reduce the noise) to give the angle to the plate and to make the plate itself circular. By changing the flow of air into a vortex to improve the fluidity of the exhaust gas, it reduces the resistance of the engine, improves the output and fuel efficiency, and reduces the noise and speeds up the flow of air. It helps.

The construction of the present invention is provided with three chambers inside the cylinder with a silencer cylinder as shown in the attached drawings. The wall is elliptical or circular between the rooms to change the flow of air into the vortex, and the angle of the wall is 15-20 °. By minimizing the contact angle between the exhaust gas and the wall by speeding the flow of air by zooming the furnace (because there is a difference depending on the diameter of the cylinder), the air flow is superior to the conventional right angle contact angle.

This reduces engine resistance, reduces noise, and improves power and fuel economy.

This design motivated me to lower the output of my own 91-year-old Le Mans passenger car, and was obsessed with finding out the cause of the job (car maintenance: 15 years of experience) and mobilized all means and methods. As a result, it was found out that there was a problem with the silencer.

[Experimental summary]

Period: 2000. 4. 3 ~ 2000. 8. 8

Car: 91 Year Le Mans (AUTO 1500cc)

Test Mileage: 4500 Km

1. Fuel efficiency: before the modification-10-11 Km

After renovation － 13-15 Km

2. Output (200 km / n arrival time):-18 to 20 seconds before modification

After renovation-15 seconds

3. Noise: Genuine – 79 to 81 dB

Equipment-84 to 85 dB

Modified Silencer-73 to 75 dB

4. The air forms vortex and the flow of air is faster, so the water discharge power generated inside is good and it is effective in durability.
