Why is the exhaust sound of the supercar so wave ?

For consumers, sound is an important factor in meeting the psychological needs of consumers. When you're blowing up the streets in a supercar, you want the whole world to know that you exist. Cool and forceful is what consumers want to have, and the existence of sound waves just meets this demand of consumers.

Of course, it is to meet the needs of consumers and meet the experience of consumers.

This is because a huge amount of energy is generated during the warm-up process of the supercar.

The speeding supercar on the track, accompanied by the sound of blood and blood, made countless teenagers fall into it and can't extricate themselves.

The exaggerated styling of the supercar highlights its sporty DNA. The manufacturer must not only let you see, but also let you hear, and the roaring sound is the most intuitive manifestation of the sense of power.

In order to attract attention, and the supercar has a low wheel, the oil engine should be fierce.

In order to meet the needs of consumers, he wants others to share his coolness.

First of all, it is very expensive, and the power is very sufficient.

The power of the car is very loud, and everyone who likes cars likes it.

That's the beauty of a supercar.

Today, Bian Xiao tells you something about cars. Recently, a friend asked Bian Xiao how to change the exhaust sound. Let Bian Xiao give you an answer. Interested friends can learn about it, it may be helpful to you.

The sports car changes the exhaust sound through a valve on the exhaust pipe.

Most sports cars are basically equipped with valve exhaust. There is a valve on this exhaust system, and this valve only opens under certain conditions.

Most sports cars switch to Sport mode and the exhaust sound basically changes, because the valve of the exhaust pipe opens when switching to Sport mode.

The exhaust valve can balance the smoothness of exhaust at high speeds and torque at low speeds.

If the exhaust pipe is too smooth, it can improve the power output of the engine at high speeds, but this will cause the engine to lose low torque.

If the exhaust pipe is not smooth, it is good for low torque, but it will lose power output at high speeds.

Of course, the sports car will be equipped with a valve exhaust.

If a friend is interested in valve exhaust, you can check the information on the Internet.

There is also an important component in the exhaust system that can affect the performance of the engine. This ingredient is known as a three-way catalyst, which creates the necessary impediment to the exhaust.

If you want to improve the performance of the engine, you can replace the three-way catalytic converter with a large flow rate, which can improve the smoothness of the exhaust.

Some motorists will immediately dismantle the three-way catalytic converter and call on them not to do so.

This is the end of Bian Xiao's introduction. After reading these introductions, do you have a certain understanding of how sports cars change the exhaust sound? I hope Bian Xiao's introduction can be helpful to you, and you can go to other pages of this site to continue reading. Thank you for your support.

Sports cars are really out of reach for ordinary us, and we can see them whizzing along the road. In addition to the cool appearance, the unique sound of the sports car can let us know what kind of car it is. But for older people who don't love cars, this is noise, and many people will still have this question, why is the sports car so loud when accelerating, is it deliberately to attract the attention of others?

First of all, we must know that the sound wave is related to the exhaust pipe, and the general exhaust pipe structure is composed of the exhaust manifold and the front section - three-way catalytic converter - exhaust middle section - exhaust tail section, and it is also equipped with a middle or tail section muffler. Of course, the number of cylinders of the engine will also affect the sound, and the sound of the engine is different from each other, so the exhaust sound is caused by the positioning of the vehicle and the engine tuning, not the louder the exhaust sound, the better the performance.

For sports cars, they pay more attention to high performance, high explosiveness and high endurance, so as to obtain more power and achieve faster speed, so they are equipped with large displacement engines. Unlike ordinary family cars, sports cars are fitted with large-displacement engines in order to get more power when accelerating to start, so a muffler with a weak sound attenuation effect is deliberately chosen to reduce the drag of the engine exhaust. That's why the higher the speed of the car, the louder the sound of the exhaust pipe.

But there are also some inconspicuous modified cars on the road that also have such a roar, and those who know the car can know by the sound that they are not the same type as sports cars, and if the modification is not good, it will sound like noise. The sound of the sports car is carefully tuned by the manufacturer, and it is a reasonable sound. Therefore, the sound of sports cars is not deliberately attention-grabbing, it is a symbol of sports car culture and part of the charm of sports cars.

It is worth reminding us that we have to respond to local regulations when modifying our cars, otherwise we will only be spending money in vain.

Was the engine sound of the sports car deliberately made so loud, or was there another reason?

It's loud and loud.

The reason for the transcription depends on the DU sound effect created by the exhaust pipe It is not the sound of high horsepower The sound of a DAO motorcycle without an exhaust pipe can completely overshadow the Ferrari When the engine is running, the pressure generated by the compressed gas inside the piston is very large, and the pressure of the exhaust is also very large, and civilian vehicles take into account the comfort, so they will use the exhaust system with a muffler, so that the exhaust sound will be low, but at the same time, it will increase the exhaust resistance and increase the burden on the engine, but the sports car is blindly pursuing speed Therefore, the loss of horsepower is not allowed, and the exhaust system uses direct exhaust as much as possible to make the engine exhaust more comfortable, which virtually increases the performance of the engine.

Sports cars, in order to achieve the purpose of running, so it is necessary to reduce the load of the engine as much as possible, including exhaust resistance, so the exhaust system of the sports car in order to make the engine exhaust gas can be discharged more smoothly, it is not like the general civilian car to consider the problem of noise reduction, as little as possible to let the exhaust gas in the silencer back and forth, so that the noise is naturally large.

Many people will say, "The reason why supercars are attractive is not only their performance, but also the role of exhaust sound." "So, if a supercar doesn't have a glamorous sound, it's likely that fewer people will love it. We can imagine how monotonous it would be to see only the visual shock in the first-class arena without the sound to match it, just like the gray and white TV had no sound in the past (of course, I do not deny the greatness of Chaplin, from the perspective of scientific and technological progress alone), people's experience of watching TV is not as good as that of modern people.

It turns out that audio-visual feasts can achieve better results, which is why more and more people like supercars.

Secondly, the reason why the supercar is called a supercar, strong power is its housekeeping ability, but to have strong power, you need a large displacement engine, and the inevitable result of large displacement and high speed is loud, not that the manufacturer's noise reduction technology is a problem, but if the muffler is effective, it will inevitably lead to an increase in the exhaust resistance of the engine and a decrease in power, thereby reducing the speed of the sports car. And too much noise reduction will not maximize the sense of presence and experience of driving, and most sports car manufacturers are developing a unique, iconic, and highly recognizable sound label that allows people to tell what car it is just by listening to the sound. And it can make the driver taller.

And there are many manufacturers who have installed "sound generators" on supercars, which can deliberately amplify the sound. It can be seen that the importance of sound to supercars.

The sports car changes the exhaust sound through a valve on the exhaust pipe.

Most sports cars are equipped with valve exhaust. There is a valve in this exhaust system that only opens under certain circumstances.

In most sports cars, the exhaust noise changes when switching to Sport mode, because the exhaust valves open when switching to Sport mode.

Valve exhaust can balance exhaust smoothness at high speeds and torque at low speeds.

If the exhaust pipe is too smooth, it can improve the power output of the engine at high revs, but it will cause the engine to lose low torque.

If the exhaust pipe is not smooth, it is conducive to low torque, but it will lose the power output at high speed.

Therefore, the sports car will be equipped with a valve exhaust.

If you are interested in valve exhaust, you can check the information on the Internet.

There is also an important component in the exhaust system that can affect the performance of the engine. This component is called a three-way catalytic converter, which will hinder the exhaust to a certain extent.

If you want to improve the performance of the engine, you can replace the three-way catalytic converter with a large flow rate, which can improve the smoothness of exhaust.

Some riders will take off the three-way catalytic converter directly, and it is recommended not to do so.
