Turbocharger or Supercharger?

Turbocharger and supercharger are terms that are often confused. Both names contain the component ‘compressor,’ which makes it easy to associate them with the same device. However, there are several significant differences that place these parts at opposite ends of the automotive spectrum.

Turbochargers and Superchargers: The Role of Induction

Before discussing the differences, it’s worth understanding the common features that connect turbochargers and superchargers. Both types of compressors are boost systems. Their operation is based on supplying compressed air to the engine, and a larger amount of oxygen allows for additional energy.

The main difference between a turbocharger and a supercharger is the power source. In turbochargers, the vehicle’s exhaust gases are used to drive two rotors – the turbine and the compressor. Superchargers are powered directly from the engine – a pulley drives gears, which in turn rotate the compressor rotor.

The New Role of Turbochargers in Modern Engines

Recently, only turbochargers have gained popularity and are eagerly used by the largest car manufacturers due to the benefits of reducing fuel consumption. Regardless of the application, turbochargers and superchargers contribute to creating extreme operating conditions, which leads to higher requirements for engine oils. Therefore, manufacturers of vehicles equipped with turbocharged engines and engines with superchargers use Mobil 1™ oils for the first, factory fill.
