How Turbocharger Works
Turbocharges and Supercharges are one of my favorite topics to talk about, these are one of the greatest engineering marvelous of its kind.
First of all let's talk about what Turbocharges
Actually both of them work on the same principle, both of them uses the same mechanism to work the only difference lies on the power source they both uses. Lets firstly talk about what is Turbochargers.
Turbocharges are a type of a forced induction system. It forces the flowing air into the engine or the combustion chamber without significantly effecting the the weight of the engine. Now the availability of the air inside the chamber is more, hence more fuel can be used and as a result we get a large boost per explosion. (READ- How car engine works to get familiar to these words.)
Turbocharges are just like turbines used in Dams to convert the heavy flow of water into rotational motion. In case of Turbocharges the fast flow of the exhaust gases via exhaust pipe is used up in rotating the turbocharges or turbine blades. Now here the blades pushes the fresh air into the intake port. The air is highly compressed and reaches the engine via inter-coolers in order to avoid knocking.
Let's understand with the help of a simple diagram of a typical Turbo Charger----
Key to the Diagram:
5- Exhaust is leaving the chamber
6- It reaches the Turbo Charger
7- Exhaust is leaving the Turbocharger with high speed as a result it rotates the blades of the other end of the other end of the Turbocharger
1- Air is sucked in due to pressure created by the rotation of the blades
2- Compressed is taken to Inter-cooler
3- Air is cooled in the Inter-cooler
4- It reaches the Intake port
Just think about it once that if you install a small turbine which can increase your car performance by 60-70%. It can achieve a spinning rate of 2,500 rps which is 30-40 times faster than most car engine.
Amazing isn't it....

Secrets Behind NOS or Nitrous
When people talk about car race or racing games, the topic of NOS generally comes up. So actually what is NOS? How it Works?
Nos, Nitrous oxide (N2O) undergoes thermal decomposition and breaks up into Nitrogen and Oxygen, when heated at 300 degree C. Hence injection of NOS provides more oxygen during combustion. Technically, more oxygen in a cylinder means, more fuel can be induced in it leading to more power from that same engine. Hence a significant boost can be obtained from that same engine.
Moreover NOS also provides a cooling effect when it vaporizes. Specifically it absorbs the heat energy of the surroundings and vaporizes, leading to decline in temperature of intake pipe and the intake air. Hence due to less temperature of the air, volume of the air decreases and mass increases, or we can say that its density increases. Overall this all again leads to more availability of oxygen for combustion.
But there is only one major problem with Nitrous Oxide is that is very much bulky. A car needs a large amount of Nos, like any gas. Normally a 6 litre engine requires around 12,000 litre of air every minute running at 4,000 rpm, so it would need a tremendous amount of NOS to run a car continuously. So, a driver can only take a few minutes of NOS even after compressing it into liquid.
