Turbocharger

TURBOCHARGER

This mainly comprises two impellers (1) keyed onto the same shaft (2), which turns on floating bearings lubricated through a branch (3) of the engine lubricating circuit.

The oil used disperses part of the great amount of heat released to the turbine by the exhaust gas.

On the turbocharger a WASTE-GATE valve (4) is fitted which is controlled by a pneumatic actuator (5) which makes it possible to shutter the passage of exhaust gas to the turbine depending on the engine's need of power/torque.
