The turbocharger is composed by the following main parts:
one turbine, one transforming valve to regulate the boost
feeding pressure , one main body and one compressor.
During engine working process, the exhaust emission flow
through the body of the turbine, provoking the turbine disk
wheel’s rotation.
The compressor rotor, being connected by shaft to the
turbine disk wheel, rotates as long as this last one rotates,
compressing the sucked air through the air filter.
The above mentioned air is then cooled by the radiator and
flown through the piston induction collector.
The turbocharger is equipped with a transforming valve to
regulate the pressure , that is located on the exhaust collector
before the turbine and connected by piping to the induction
collector.
It’s duty is to choke the exhaust of the emissions , releasing part
of them directly to the exhaust tube when the boost feeding
pressure, over the compressor, reaches the prescribed bar
value.
The cooling process and the lubrication of the turbocharger
and of the bearings is made by the oil of the engine.
