What is Supercharger?


It is a device, either mechanical or electronic in modern applications, that attaches to the engine with the purpose of increasing air intake into the combustion chamber.

How Does a Supercharger Work?

It operates by compressing air and delivering it to the engine’s combustion chamber, allowing for increased air intake and improved performance. It is typically belt-operated and driven by the engine’s crankshaft. Unlike a turbocharger, which utilizes waste exhaust heat, a supercharger draws in air directly. This compressed air enables the engine to burn more fuel, resulting in enhanced performance.

However, using a super-charger comes with an initial cost and can lead to a reduction in horsepower by up to 20%. Nevertheless, the net gain in horsepower is generally between 30% and 50%, making it a viable option for boosting a vehicle’s power output.

What are the Different Types of Superchargers?

They come in four distinct types, each with its unique characteristics:

1. Roots Supercharger: The oldest among them, this charger employs a pair of rotors to capture and deliver air to the intake manifold. This process pressurizes the intake manifold located between the supercharger and the engine.

2. Twin-Screw Supercharger: Similar in appearance to the Roots supercharger, the twin-screw variant compresses air within its housing by propelling it between two interwoven screws.

3. Centrifugal Supercharger: It takes a different approach, forsaking rotors for an impeller fan that draws in air. This air can be directed either to an intercooler or straight into the engine.

4. Electric Supercharger: The newest addition to the group, this charger functions like a centrifugal supercharger but utilizes an electric motor to pressurize the intake air. This type can be found in select 48V hybrid systems.

What is a Tesla Supercharger?

A Tesla Supercharger is a proprietary high-voltage direct current (DC) fast-charging network established by Tesla, Inc. exclusively for their electric vehicles. It is purposefully designed for rapid charging. As of September 2023, Tesla operates a widespread network of 50,000 plus superchargers.
