Emporio Rossi sells turbines branded Holset or Garrett. The turbine, or turbocharger, is a mechanical organ that uses part of the energy contained in the exhaust gases to turbocharge the engine, significantly improving its performance. The turbine is composed of two parts: the so-called “hot” side in contact with the exhaust gases, and the “cold” side where the turbine draws in the air to be compressed and introduced into the engine. Technically it is composed of two impellers, the first of which is rotated by the kinetic energy of the exhaust gases. This rotation is then transmitted to the intake impeller by means of a metal shaft; the air is compressed and introduced into the intake manifold to a much greater extent than that normally available to a normal aspirated engine.

Because the engine will deliver more power, exhaust gases will be emitted faster, feeding even more to the turbine. In this way, the turbine can achieve tens of thousands of rotations per minute. In order to prevent the compression ratio from exceeding the threshold values beyond which both the engine and the turbine could be damaged, protection mechanisms have been developed: they mainly consist of valves whose purpose is to limit the exhaust gas flow.
