3. INTRODUCTION
 Automobile Silencer is a device used to reduce the noise
produced by the engine. Silencer is used in automobile vehicles to
reduce the noise produced by the exhaust gases of the engine.
Silencer is also used in many other engines and generators. The
size, shape and construction vary according to the type and size
of the engine. The primary function of the silencer is to reduce
engine noise emission.
 We can use the pressure energy of hot gases and we can convert
the kinematic energy in to mechanical work and by mechanical
work we can generate electricity
 We will install a mechanism with axial high pressure reaction
turbines with a backward curved reaction turbine (Exhaust Fan
Blade) in a single shaft with a electrical generator

4. OBJECTIVE
 Reduce hot spots, especially at the mating areas/ joints near
the exhaust manifold
 Improve the life of the components by reducing the
incidence of uneven or non-uniform heat distribution
causing mechanical failures

5. SIGNIFICANCE
 There is an ever-increasing demand for energy in the present age and
most conventional sources of energy like coal, oil and natural gas used
today are non-replenish able.
 This experimentation model, power generation using vehicle silencer is a
simple and innovative method of non-conventional energy generation.
 Electrical power is generated using the waste gases emitted by the vehicle
silencer, that are otherwise emitted into the atmosphere using a simple
mechanism such as DC generator and silencer.
 The power thus generated may be stored in a re-chargeable battery and
can be used for other purposes.
 This method can be implemented on all two-wheelers and four-wheelers.
 This model is simple and very cost effective.

6. LITERATURE REVIEW

7. PROBLEM IDENTIFICATION
 HISSING SOUNDS: Most of the exhaust problems occurs due to
faculty exhaust manifold gasfold.
 LOUD ENGINE NOISES: Problems like the corrosion of bike silencer
can make themselves noticeable through loud engines noises
 OBNOXIOUS ODOUR: If catalytic converter malfunctions, harmful
gases like – carbon dioxide, carbon monoxide released then this give
very bad smell.
 LOWER MILEAGE: Issue in your exhaust system can put a damper on
your fuel economy this results in reduce in mileage of your bike.
 CORROSION: Rust is the often main problems of the many bike
silencer.

8. METHODOLOGY
 It will be installed in exhaust system. It will be a mechanism of axial high pressure
turbine and backward curved fan blades with a electrical generator.
 The air will strike on high pressure reaction turbine and the pressure energy will
convert into mechanical energy. This shaft will also be rotate fan blade that will
increase the discharge rate.
 The improvement in discharge rate will increase the engine power because high
pressure discharge means low pressure drop in exhaust system. If the pressure
drop will be low the power will increase of the engine.
 The electrical generator will rotated by the same shaft and the electricity will be
produced by generator.

9.  The turbine is fixed to the shaft of the generator. Aluminium is the
preferred material for the turbine, because of its high heat conductivity.
This aids faster cooling and less weight.
 The fixture is enclosed within an aluminium frame. Turbine is placed at
the exit of the silencer. The turbine blades are placed in a position where
the exhaust gases from the silencer hits the blades directly.
 As the turbine spins along the shaft, the generator produces electricity.
The ideal capacity ofthe generator, considering its size and weight, would
be 12V.
 The produced current is passed through a regulator, which would be
stored in a DC rechargeable battery of matching capacity (12V, 1.3AH).
 Inverter is used to convert the DC stored in the battery to required AC
output i.e. 230 v.
 If necessary transformer is used to regulate the voltage to meet the
demand of the output.
 The entire experimentation model is to be housed on the silencer.

15. FORMULA TO BE USED
 Area of Swept, A= (22/7) x (radius of turbine) 2
 Velocity of the Turbine= ((22/7)x D x N)/60
 Where
D=diameter of turbine
N=number of revolution per minute

 P= (1/2) x Density x (Velocity) 3xCpxArea

16. MODEL CALCULATION
 Swept area by the turbine, A = (22/7) x radius2
= 3.14 x (0.05) 2

 Velocity of the turbine, V= ((22/7) x D x N)/60
= (3.14x0.10x45)/60

 Power available at the turbine,
= 1/2x density x area x (velocity) 3 x Cp
= 1/2 x1.23 x 0.00785 x (0.2357)3x0.4

 The efficiency obtained was 5.078%.

18.  The graph shows that the power output is function of

TEG was 15.225 W.

19.  The graph explains that the current increases with the

rapidly beyond that speed. At the speed of 3970 RPM the
current was 1.45 A.
