Turbochargers compress air flowing into an engine using a turbine spun by exhaust gases. This allows more air and fuel in the cylinders, increasing power without increasing engine size. A turbocharger has a turbine and compressor connected by a shaft. The turbine spins the compressor to boost intake air pressure, enabling more air and fuel for combustion. While turbochargers provide more power and efficiency from a smaller engine, they also increase engine weight and require more space.

1. Turbocharger

2. Introduction:
• Turbochargers are a type of forced induction system.
In order to achieve the boost, the turbocharger uses the exhaust flow from the engine to
spin a turbine, which in turn spins an air pump.
They compress the air flowing into the engine.
The advantage of compressing the air is
that it lets the engine squeeze more air into a
cylinder , and more air means that more fuel can
be added. Therefore, you get more power from
each explosion in each cylinder.

4. part of Turbocharger:
1- Turbine: turbine wheel and turbine housing.
2- Compressor: Compressor wheel and compressor housing.
3- Center housing (bearing housing): Rotating shaft.

5. 4-Wastegate: The wastegate job is to divert excess exhaust gases away
from the turbine - controlling the speed of the turbine and preventing it
from spinning too fast. By controlling and limiting the speed of the turbine,
the wastegate regulates the boost pressure provided by the turbocharger.

6. 5-Intercooler: When air is compressed, it heats up; and when air heats up, it
expands. So some of the pressure increase from a turbocharger is the result
of heating the air before it goes into the engine.
An intercooler or charge air cooler is an additional component that looks
something like a radiator, except air passes through the inside as well as the
outside of the intercooler.

7. How does it work?
A turbo is made up of two halves joined together by a shaft. On one
side, hot exhaust gasses spin the turbine that is
connected to another turbine which sucks air in and compresses it
into the engine. This compression is what gives the engine the extra
power and efficiency because as more air can go into the combustion
chamber, more fuel can be added for more power.

9. Advantage of Turbocharger
1- Increased power from the engine of same size or reduction in size of
engine with same output.
2- Reduced fuel oil consumption.
3- no loud on the engine.
4- Pollution the smoke is reduced due to used turbocharging engine
because combustion is good .when smoke is less produce then that
engine create pollution is also less.

10. A disadvantage of the Turbocharger:
1- Engine weight
When turbocharging is used in engine then various component is
increased so engine weight is increased.
2- Space and area
Turbocharging engine is required more area and space than the other
engine these is also disadvantages of turbocharged engine.
3- Turbocharger lag (turbo lag) refers to the amount of time required for
the turbocharger to increase intake (charge air) pressure to the target
level.
