Description
What Is a Turbocharger?
People from the 1980s are likely to be better acquainted with the
word ‘turbo’ because it was applied to plenty of products at that
time such as turbo skateboards, turbo razors, and many other
things. But, this is not what has revolutionized the auto industry.
A turbocharger is a turbine-driven forced induction machine that
boosts the efficiency and power output of an internal combustion
engine by bringing additional air into the combustion chamber.
If it seems a bit complicated to understand how a turbo works, take
the cue from the fact that an engine run by a mixture of fuel and
air. When a turbocharger brings more air into the chamber, it gets
mixed with more fuel, yielding more power as a result. It smuggles
air by compressing it using the energy of the exhaust gasses coming
out of the engine.
Where Do Turbochargers Come From?
The first turbocharger was produced in the late 19th century by
German engineer, Gottlieb Daimler, but they didn’t come to
prominence until after WWI, when aircraft manufacturers began
adding them to aeroplanes to provide power to engines operating at
higher altitudes, where the air is thinner.
Turbochargers weren’t added to car engines until 1961, when US
manufacturer Oldsmobile, used a simple turbo to boost the power of
a 3.5L V8 engine. In 1984, Saab developed a new, more efficient
turbo system, and this design, with a few tweaks and modifications,
remains the most popular turbocharger configuration today.
Efficiency vs Driving Style
Achieving the claimed efficiency figures of a turbocharged engine
requires careful throttle control, whereby the accelerator isn’t
pressed too hard. When a turbocharger is ‘on boost’, the cylinders
are burning fuel more quickly, leading to poor efficiency. Drivers
going from a naturally-aspirated car to a turbocharged model may
need to adjust their driving style to maintain good efficiency,
particularly when first setting off.
