WHY TURBOCHARGER?

* Power diminishes with an increase inaltitude.

* Gain more power and increaseengine efficiency without enlarging the

powerplant.

* Recapture the heat energy normallywasted out the exhaust.

HOW A TURBO WORKS

a turbocharger comprisesof a turbine and a

compressor connected by

a common shaft supported

on a bearing system. The

turbocharger convertswaste energy into

compressed air which it

pushes into the engine.

This allows the engine to

produce more power and

torque and improves the

overall efficiency of the

combustion process.

driven directly by the engine.

Working of exaust gas turbocharging

In exhaust gas turbocharging, some of the exhaust gas energy,

which would normally be wasted, is used to drive a turbine.

the turbine is a compressor which draws in the combustion air,

compresses it, and then supplies it to the engine.

TURBOCHARGER COMPONENTS

The turbine housing

inlet flange acts as the

reference point for

fixing turbochargerposition

The Turbine Wheel is

housed in the turbine

casing and is connected

to a shaft that in turnrotates the compressor

wheel.
