Turbocharged and Supercharged Engines



Usually whenever we talk about performance of cars, words like “Turbocharger, Turbocharged Engine, and Supercharger” come across. Chances are you might even have one of these in your car but are unaware of what exactly they do. Let’s see how these work and how do they differ.                                                    

                                                         Turbochargers & Superchargers


The combustion engine in our cars generates some power, which is usually more than enough to make them run. Turbochargers are usually employed in high capacity diesel engines. What they do is, they boost an engine’s horsepower without making any modifications to the engine. Many car aficionados, who are power hungry, end up fixing a turbocharger into their beasts.


Technically, turbocharger is a type of forced induction system that compresses the air that gets sucked in by the engine. Compressing the air allows more air (by volume) to enter into each cylinder of the engine. The same mixes with more fuel that finally leads to more power. More importantly flow of the exhaust air is used for the turbocharger turbine to spin the air-pump.

Another way to add more power to your engine is to engage a supercharger. What turbochargers and superchargers do is the same thing (boost the engine power), a supercharger is however bolted onto your car’s engine as it runs from the engine itself, much like the A/C components, and Supercharger is powered mechanically by chain or belt drive system from the crankshaft. So it actually takes off a chunk of power generated from the engine, making it work more for the power that you needed it to provide you with.
