Description
How Does a Turbocharger Work?
A turbocharger is made up of two main sections: the turbine and the
compressor. The turbine consists of the turbine wheel and the
turbine housing. It is the job of the turbine housing to guide the
exhaust gas into the turbine wheel. The energy from the exhaust gas
turns the turbine wheel, and the gas then exits the turbine housing
through an exhaust outlet area.
The compressor also consists of two parts:
the compressor wheel and the compressor housing. The compressor’s
mode of action is opposite that of the turbine. The compressor
wheel is attached to the turbine by a forged steel shaft, and as
the turbine turns the compressor wheel, the high-velocity spinning
draws in air and compresses it. The compressor housing then
converts the high-velocity, low-pressure air stream into a
high-pressure, low-velocity air stream through a process called
diffusion. The compressed air is pushed into the engine, allowing
the engine to burn more fuel to produce more power.

And What are the Downsides?
Expensive Repair Costs
Turbochargers add complexity to an engine, with a whole host of
other components beneath the bonnet that can fail or develop
faults. These problems can be expensive to put right, and can have
an impact on other components if they fail.
Turbo Lag
Turbo lag is a brief delay in response after pressing the throttle,
which can occur when the engine isn’t producing enough exhaust gas
to spin the turbo’s intake turbine quick enough. This only really
happens when the car is being driven aggressively, or from a closed
throttle position. In high-performance cars, manufacturers prevent
turbo lag by adding two turbochargers of differing geometry, rather
than one big one with only a single turbine.
