TURBOCHARGER
The turbocharger increases the air flow rate during the suction stroke of the combustion cycle. The contribution of extra air
improves combustion and increases engine efficiency.
The exh aust gases are conveyed towards the turbocharger turbine where th ey give part of their energy and turn the turbine
itself. During thi s step, the exhaust gas temperature drops to approximately 600˚C.
A centrifuge compressor is mounted coaxially to the turbine with the task of aspirating and comprising the previous cleaned
air from the external environment.
During compression, the air temperature increases and is thus cooled by a heat exchanger (intercooler) before being conveyed
to the intake manifold.
