Understanding Turbochargers- The Inside Story

Updated on September 1, 2016

There's no such thing as a flawless innovation: we can simply improve something, less expensive, more productive, or all the more ecologically benevolent. Take the internal combustion engine for example. You may believe it's astonishing that a machine controlled and driven by fluid can throw you down the highway or fling you through the sky ordinarily quicker than you could through some way. However, it's always possible to fabricate an engine that will go quicker, further, or utilize less fuel. One such approach to enhance an engine is to utilize a turbocharger—a couple of fans that outfit waste fumes power from the back of an engine to pack more air into the front, conveying more "oomph" than you'd generally get. We all know about turbos, however how precisely do they work? Let us find out


The historical backdrop of the turbocharged engine is nearly as old as the creation of the internal combustion engine. In this time Gottlieb Daimler (1885) and Rudolf Diesel (1896) endeavored to reduce the fuel consumption of the engine and also increase the force by precompression of air supplied to the engine.

What are Turbochargers?

Automakers are assembling their littlest, most fuel-proficient engines ever, while keeping strength upbeat individuals fulfilled. They're doing it with turbochargers, which help four-cylinder engines yield as much power as their conventional V-6 partners.

A turbocharger is basically an exhaust driven air compressor. Also, since an engine’s efficiency/output is defined by the amount of air (blended with fuel) it can pump, a turbocharger helps it inhale better thereby increasing the efficiency. Basically turbocharger utilizes two fans ("turbines") mounted on a solitary shaft.

Each of the fans work inside a different corridor and are spun utilizing the same standard as an ordinary water wheel. The principal fan is spun by exhaust gasses coming out the engine. This first fan drives a second fan working in the other passage, where approaching air is being directed into the engine —pressurizing (pushing) fresh air into the engine in the process

One fan turns from exhaust going out and the other fan pushes fresh air coming in. The more you pound down on the gas pedal, the more the exhaust gasses drive the support of incoming air into your engine. More air helps the engine to create more power, and zoom you go!

Turbochargers and superchargers are known as forced induction systems. It implies that either will pack the air streaming into the engine, which gives more energy to the car (turbochargers were introduced to increase efficiency of the engines, keeping the power intact, not for reasons like exhaust notes). A primary distinction between the turbocharger and the supercharger lies in the force supply.

Difference between Turbocharger and Supercharger


  • Uses exhaust stream for its energy, that runs through a turbine which in turn spins the compressor
  • It is not directly connected to the engine
  • Has smog altering equipment that lower the carbon emission


  • Uses crankshaft for its energy and produces power for the engine
  • Directly connected with engine through a belt
  • Does not have waste gate. So, smog emits from the supercharger.
