The Purpose of Turbochargers

The Purpose of Turbochargers

By Ron Haugen




A lot of people do not know that turbochargers are actually a kind of a supercharger. The turbocharger used to be called a turbo supercharger. It was not long before the name was shortened. It is important to know what a turbocharger does and how it works. However, keep in mind that it is a lot of work to install these yourself or do any type of work on them. It is always a good idea to get an ASE certified mechanic to help you out with this.

Purpose of the Turbocharger

The turbocharger is made to compress the oxygen that comes into the engine of your car. When the oxygen level is increased it will increase the overall power output. Whenever the oxygen is compressed it will allow more to come into the engine in a shorter amount of time.

Turbocharger VS Supercharger

A supercharger is belt driven. However, the turbo charger is powered by the exhaust gases of the vehicle. Basically, a turbocharger will take a byproduct of the vehicle's engine that would usually not have any use. It will use this to get the horsepower of the vehicle increased dramatically. If a vehicle does not have a super charger or a turbocharger, then it will be called normally aspirated. These types of vehicles will have air drawn into them through the air filter. The air will then go through the meter. This will in turn regulate and monitor the air that goes into the system. This air will then be delivered straight into the combustion chambers of the engine.

Parts of Turbocharger

The turbocharger will be made of 2 parts. The first part is the compressor. The compressor is what compresses the air intake to the engine. It is what causes more air to get to the engine in a shorter amount of time. The other part of the turbo charger is the turbine. The turbine will take in the exhaust gases and then use them to power up the compressor. Something else that is often talked about with a turbocharger is the boost. This is the amount of the pressure in the air for the intake is exposed to. The more air that is compressed into the engine means the higher of a boost you can get.

Considerations

It is important to remember that a turbocharger engine will have a compression ratio that is lower than a normally aspirated engine. Because of this you not be able to put a turbocharger on with an engine that was meant to be normal aspiration. If you do this, then you will be putting the overall performance and the life of the engine at risk. You should also keep in mind that the lower compression ratio will mean that your engine will run a lot less efficiently when it is at a lower power. It is a good idea to go to an ASE certified auto technician to discuss what can be done to get a turbocharger safely and effectively put onto your vehicle.
