Description
What is a Turbocharger?
As a little-know fact, a turbocharger is actually a type of
supercharger. Originally, the turbocharger was called a
"turbosupercharger." Obviously, the name was shortened out of
convenience.
A turbocharger's purpose is to compress the oxygen entering a car's
engine, increasing the amount of oxygen that enters and thereby
increasing the power output. Unlike the belt-driven supercharger
that is normally thought of when one hears the word "supercharger,"
the turbocharger is powered by the car's own exhaust gases. In
other words, a turbocharger takes a by-product of the engine that
would otherwise be useless, and uses it to increase the car's
horsepower.
Turbochargers often work with an engine's carburetor.
Cars without a turbocharger or supercharger are called normally
aspirated. Normally aspirated cars draw air into the engine through
an air filter; the air then passes through a meter, which monitors
and regulates the amount of air that enters the system. The air is
then delivered to the engine's combustion chambers, along with a
controlled amount of fuel from the carburetor or fuel injectors.
A turbocharger's purpose is to compress the oxygen entering a car's
engine, increasing the amount of oxygen that enters and thereby
increasing the power output.
In a turbocharged engine, however, the air is compressed so that
more oxygen will fit in the combustion chamber, dramatically
increasing the burning power of the engine. The turbocharger is
composed of two main parts: the compressor, which compresses the
air in the intake; and the turbine, which draws the exhaust gases
and uses them to power the compressor. Another commonly used term
in relation to turbochargers is boost, which refers to the amount
of pressure the air in the intake is subjected to; in other words,
the more compressed the air is, the higher the boost.
Although the increase in power is advantageous to the car -- and
likely a source of enjoyment for the driver -- a turbocharger has
its drawbacks. First and foremost, a turbocharged engine must have
a lower compression ratio than a normally aspirated engine. For
this reason, one cannot simply put a turbocharger on an engine that
was intended for normal aspiration without seriously undermining
the life and performance of the engine. Also, a lower compression
ratio means the engine will run less efficiently at low power.
