The Invention of the internal combustion engine - an internal combustion engine - can rightly be attributed to one of the greatest inventions of mankind. He gave man the power which is not possessed of muscles, and much human genius has been able to adapt this power to meet their needs in different areas of its activities. And it also ensured the rapid development of many related fields of science and technology, making atmospheric engine continued to evolve and improve.
To understand the problems faced by engine builders, you have to remember how to work this engine. We consider an ordinary gasoline engine. He sucks from the atmosphere the air which is then mixed with the vapor of the gasoline and fed into the combustion chamber. When combustion occurs the gases expand, causing the forces of the rotating crankshaft. So, speaking very simplistically, is the description of how an engine works.
Here you need to pay special attention to the following points. First, the fuel burns down not completely, as evidenced by the presence of unburned particles in its exhaust gases. Second, the exhaust gases have sufficient energy, and would like to use. The solution was found - the installation of the turbine on an engine. The approach is very simple: just don't burn the fuel, so he's not getting enough oxygen, you need to add into the cylinders the air, and it can be done with the exhaust.
What is described above – this is the working principle of a turbo engine. The exhaust stream emitted to the atmosphere, is the impeller of the turbine, it drives the associated compressor, which pumps pressurized air into the cylinders of the engine, providing additional oxygen for more complete combustion of the fuel. The actual design is much more complicated as described, but the operation of the turbine of the supercharging is carried out in this way.

There is another way to ensure a boost – to use compressor with drive motor. The disadvantage of this option is a loss of power engine, because the compressor will take the power from the motor. Although this option of mechanical supercharging is used in some cases as additional to the described turbocharger system. He is particularly effective at low engine speeds, and then, the growth speed is disabled.
Due to the described way of the turbo, normal aspirated engine with the same parameters gets additional power and increased efficiency, which is due to more complete combustion of the fuel. This is one of the simplest options to increase the power of the motor. It is used for both petrol and diesel engines. In this case, between them there is no difference.
The Characteristics, which shows the atmospheric engine can be improved without a major upgrade through the use of turbocharging. It is estimated that the power of the engine could increase by 40% and, in addition, the amount of harmful substances in the exhaust gases is thus reduced.
