The turbocharger gives a simple and easy way to enhance engine power. The turbocharger as well as supercharger act like pumps which stuff air into a cylinder, that when burned using added fuel produce more combustion pressure and greater power. You should note that supercharger runs off a crankshaft, like a power-steering pump and alternator, and due to this it needs some power for performing its task.
The turbos are powered using the wasted energy which flows out of an exhaust pipe. There are two fans connected by one common shaft. The first fan is placed in exhaust stream, while the other in intake. The fan or turbine spins due to the flowing exhaust and this gives power to the subsequent fan found in the compressor or intake.

The turbos are always effective to increase the specific power of engine that is also called the output per displacement. The turbo 2.0-liter four-cylinder engine could simply match the power generated by a 3.0-liter naturally aspirated V6 engine. The first production car that used turbo was 1962 Chevrolet Corvair. Porsche popularly used the turbo in its model 911 Turbo during the later part of 1970s.
As one side of turbo is placed in an exhaust stream, the heat is generally a difficulty. Decreasing the temperature of exhaust stream for avoiding the failure of turbo needs an extra fuel. The modern turbos gain from a housing of stainless-steel (rather than cast iron) as well as superior nickel-alloy turbines. The turbos should withstand a very high temperature so that the engines could operate much near to the perfect stoichiometric air/fuel ratios and this enhances the fuel economy.
If the fuel is injected directly into combustion chamber rather than a more conventional place – intake stream – then the fuel considerably cools intake charge. The cooling effect produced decreases the potential of harmful detonation or preignition and this allows engineers in specifying more efficient and higher compression ratios.
The turbochargers are coming back in vehicles with style. As new technologies are coming up there is a requirement of fuel-efficient power. Due to this there is a fantastic rise in the use of turbo engines in auto industry.
