CAUTIONS IN USING THE TURBOCHARGER
WHAT IS THE TURBOCHARGER?
Turbochargers are based on gas turbine en-
gine technology, but operate under consid-
erably greater pressure. The turbocharger
consists of two turbo elements, a turbine and
a compressor, both of which are driven from
the main center shaft. The turbine rotates be-
tween 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 cyl-
inders in compressed from. As more fuel is
drawn into the engine, output 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
What is the intercooler?
The inter-cooler cools down the compressed
air temperature to increase the engine power
by increasing the air density.
