TURBO CHARGER SYSTEM 5–3
What is the Turbocharger?
Turbochargers are based on gas turbine
engine technology, but operate under con-
siderably greater pressure.
The turbocharger consists of two turbo el-
ements, a turbine and a compressor, both
of which are driven from the main center
s h a f t . T h e t u r b i n e r o t a t e s b e t w e e n
50,000~160,000 spins per minute and uses
the energy of the exhaust gas to drive the
compressor. The compressor, in turn, draws
in fresh air which it supplies to the cylinders
in compressed from.
As more fuel is drawn into the engine, out-
put performance is boosted between 15-
30% in comparison to a non-turbocharged
engine.
Advantages of a Turbocharger
Turbocharger helps the engine operate more
smoothly and with greater efficiency.
•
Increase specific power
•
Compensate for power loss at altitude
•
Reduce emissions and noise
