Ask an engine expert about sound effects?

The sound is adjustable, and if you look at the racing version of the GTR, the sound is absolutely embarrassing to most street cars, and it's actually any kind of car that sounds like a roar, even the little steel cannons, because cars don't need to think too much about that.

There are two things to do here, one is the sound of the engine itself, and the other is the sound of the exhaust, and a factory like Ferrari also pays attention to the sound when it builds a car, and it mostly does this by changing the exhaust system, and the racing version of the 458 only has two exhaust pipes, because the car doesn't need the third one to adjust the sound.

And like the SLS AMG, the sound is the standard AMG beep, it's naturally aspirated, but it's completely different, and the tone can't be raised at any time, and what you hear is basically the sound of the engine running.

There was a time when F1 was turbocharged, and F1 has always been deafening.

And what affects the pitch is the rev and the compression ratio, and even the most high-profile engine only hums at low rpm, and turbocharging is a device that reduces the speed, of course, for ordinary cars.

You can go to the WRC, where turbocharging is allowed, and it's absolutely squeezing, and the F1 is sharper than his pitch.

There's a saying that the turbocharger itself acts like a muffler, so I don't think it's possible for a supercar with a turbocharged engine to achieve the exaggerated, frequent, and exciting sound of supercars like Ferrari and Lamborghini? (Actually, I don't seem to have seen it, for example, the GT-R is relatively low) PS: I like the sound of the Ferrari 458 Italia 458 Spider the most.

The sound of the car is generated by the engine and exhaust pipe. By modifying the exhaust pipe, the car can make a sound, and adding turbocharging can also make the car make a special sound.

The so-called sound is the sound made by the exhaust pipe of a car. Whether the sound is good or not has a lot to do with the material of the exhaust pipe, and the most common exhaust pipe is 409 stainless steel, which is used by many car manufacturers to make exhaust pipes. Not all stainless steels are created equal.

The damage of stepping on the accelerator on the neutral gear bridge is very large, and it is not recommended to use it frequently, because each manufacturer has different locking logic adjustment for the torque converter, some cars can not do complete power separation, and the car needs to step on the floor oil when stepping on the sound during driving, which will quickly increase the speed of the car in a short time, and the output power of the engine will be very large, instantly increasing the speed of the car.

At the same time, it will also produce high fuel consumption, it is not recommended to use this way, some owners who like to modify the car will modify the exhaust of the car, remove the muffler of the exhaust, the engine is directly exhaust to the external environment, the noise generated is relatively large, the engine with turbocharging even if the exhaust is not modified, the car will produce sound waves during acceleration, but the sound of this exhaust is relatively small, because the exhaust pipe of the car has a muffler.

Four-cylinder motorcycles, because the power provided by unit mass and unit displacement is much greater than that of four-cylinder cars, so its manufacturing accuracy is higher than that of automobile engines (which is also the main reason why China cannot mass-produce four-cylinder motorcycle engines), with high precision and high speed, making the sound of four-cylinder motorcycle engines more shocking than ordinary family car four-cylinder engines.

BMW's twin-cylinder car is a "boxer" engine that is asynchronous in opposite directions, which naturally involves the problem of accuracy, and a single piston reaches a volume displacement of 400-600cc, and the sound is naturally non-domestic functional comparison.
