What Is a Turbocharger in a Car?

The turbocharger is a car engine part that boosts the engine’s power. Its role is to increase fuel economy and boost horsepower. It also alters the exhaust sound. Generally, a turbocharger is found in vehicles with a carburetor.

Boosts fuel economy

New technology is available to boost your car’s fuel efficiency. These devices use magnetic technology to clean fuel lines and make your vehicle run more efficiently. This not only improves the performance of your car but also reduces your gas bill. You might have yet to realize this, but removing old seats and keeping only the essential items inside your car can help you get better fuel economy.

A good overdrive gear can also improve fuel economy. It reduces engine speed and reduces engine wear. Avoid using air conditioning, which can decrease fuel economy by 10%. Run your A/C at a low rate, or turn it off. The air conditioner will also increase wind drag, which uses fuel more than it saves. Using the correct grade of oil in your car is also essential. Using the recommended oil grade will improve fuel economy by about one to two percent.

An Eiffel performance chip is another option that can increase fuel efficiency by fifteen to thirty percent. It works by reading data from the vehicle’s onboard computer and making minor adjustments as necessary. It’s similar to a mechanic remapping your car, but it’s cheaper, and you can get rid of it anytime. If unsatisfied with the results, you can get your money back.

Changes exhaust sound

The changes in the exhaust sound of a turbocharger can be attributed to how the turbocharger adds damping to the pressure waves produced by the engine. The transmission loss of a turbocharger is measured in dB-s. It is proportional to the amount of damping the pressure waves gain in the downstream and upstream directions. In addition, a turbocharger produces a very high-frequency aerodynamic noise masked by modern exhaust systems.

While it is not the same as a police siren, a turbo whistle signifies that the compressor wheel is damaged and the turbo is causing excessive noise. The turbo whistle can be heard as the engine revs up. While most people do not notice this noise, it can indicate several problems with the turbo.

Turbo exhaust systems create a burbling and rhythmic noise. Because the exhaust-side impeller is revolving, the sound is made at an angle of 90 degrees, much like the propeller of an airplane. It also produces a more consistent sound than a naturally aspirated engine.

Some vehicles have a blow-off valve in their exhaust systems. This valve relieves pressure generated by the turbo during a boost cycle. Without it, the pressurized air would force its way back through the turbo, exposing a weak point in the plumbing. The blow-off valve can produce various sounds, including a flutter-like sound.

Some people choose to make exhaust system modifications on their own. But if you are not experienced, it is better to seek professional assistance. Also, make sure you have the proper tools. If not, you may cause damage to the turbo. You may choose a turbo whistle to make the exhaust sound louder, but the turbo will no longer sound genuine when driving under heavy acceleration.

While several factors can cause the exhaust sound to change, airflow is the most common. When air flows in too slowly, the compressor blades will not be able to dissipate the incoming air, forcing it to be recycled back into the turbo.

GM Powertrain and Volvo Car Corporation supported the research. The researchers also received funding from the Estonian Science Foundation (Nr. 7913). You can follow these scientists on Twitter and IG. They also have a Facebook page. These are just a few reasons you should check out their website. You’ll be glad you did. When you’re done, it’s time to upgrade your turbocharger.
