How the turbocharger works

The turbocharger is usually located on the intake manifold; it consists of a turbine wheel, which is driven by the exhaust gases and is located inside a “spiral” element, and a compressor wheel, connected to the turbine through a small shaft. The compressor, set in rotation by the turbine, compresses the air and introduces it into the intake manifold , bringing a greater volume of air to the engine cylinders consign a car.

Advantages of the turbo

This allows more mixture of air and petrol to be introduced into the combustion chamber, thus ensuring greater performance in terms of power and acceleration. The use of a turbocharger therefore increases efficiency as a whole because the residual energy of the exhaust gases is used to increase the power of the engine itself.

Limitations of the turbo engine

However, there are compression limits beyond which problems such as detonation or engine damage occur. To avoid exceeding a certain compression ratio inside the cylinders, valves are used such as the wastegate (which eliminates the excess gases that would cause the turbine to rotate excessively) and the pop-off valve (which opens during the release of the gas when, although the throttle is closed, the turbine continues to rotate due to the effect of inertia, compressing the air which, however, is no longer introduced into the cylinders).
