The Purpose and Functionality of Heavy Duty Mufflers on A Vehicle

The importance of heavy duty mufflers on a vehicle cannot be overlooked. To understand its significance and effects on the performance of the vehicle first, you need to know what exactly a muffler is. According to the literal definition, a muffler, also known as a silencer in British English, is a device used to decrease the amount of noise emitted by the vehicle through the exhaust of its internal combustion engine.

Especially those vehicles that are modified usually emit a huge amount of noise that can be very annoying to others and even the rider. Usually, there are few specific rules of law set regarding such noise emission and auto companies must keep these rules in mind while designing a new vehicle type. In comes the muffler to reduce the noise and pollution.

Features and Functions of a Muffler

The structural feature of the heavy duty mufflers makes it a double-edged sword. Though it reduces the noise emitted by the engine of the vehicle, at the same time it increases the level of resistance in the exhaust system. That means the vehicle will function at a reduced horsepower eventually. To eliminate this issue with the engine there are a few crazy car lovers who prefer replacing the muffler with a three-way catalytic converter.

In the typical structure of the mufflers, there is a fair amount of acoustics involved. These acoustic features results in the physical working principle of the muffler in your vehicle.

  • This specific design and mechanism typically cools the exhaust gases.
  • These gasses expand through the heavy-duty mufflers eventually reducing the noise of the outgoing gases
  • The exhaust gases are discharged to the atmosphere feeling a minimum restriction
  • The reduced restriction in the flow of exhaust gases eliminates back pressure on the piston head.
  • In short, the muffler keeps this pressure usually within 0.7 and 0.9 Kg/cm2 when it is at maximum rpm thereby reducing fuel consumption.

Importance of a Muffler

You will find these heavy-duty mufflers on every single vehicle that ply on the road. These not only reduce sound emission and pollution but will also boost the power and performance of the engine provided you upgrade it timely.

The magic of these mufflers occurs when it controls the exhaust valves of the engine that open up continuously to release the highly pressurized gas. While traveling as a great speed through the exhaust pipe these thousands of molecules of gas sound bursts every minute. These noises keep bouncing in the pipe and eventually released becoming a potentially very annoying and loud sound. This is reduced by the heavy duty mufflers.

The Working Principle

The key working principle of the heavy duty mufflers is then to find a way to minimize the sound level inside the pipe before it leaves the exhaust system becoming a loud noise.

  • Tuning Engine Noise – This is done by mounting the mufflers typically at the very end of exhaust tips. It is the baffled chambers or the series of perforated tubes specifically designed that tune up and minimizes the sound output of the engine. The sound waves bounce against and around the baffles which creates opposing sound waves. This cancels the large sound output.
  • Maximizing Performance – This is ensured by getting rid of the exhaust gases faster from your engine. That means the engine will be able to take in fresh oxygen faster and therefore generate more power. Therefore, with the efficient exhaust flow, the power output and performance of your engine is enhanced.

Heavy duty mufflers play a key role in reducing the noise level of vehicles and are also corrosion resistant. They are long lasting and provide improved flow and are easy to maintain. There are many different types out there. Choose the right type of muffler as according to your performance required, keeping with the state laws.  You should get good quality heavy duty mufflers if you don’t want loss of power and decrement in fuel efficiency.
