This document presents a design for generating electricity from exhaust gases. It includes an introduction describing how pressure energy from hot gases can be converted to mechanical work to power an electrical generator. The major components are described as a backward curved turbine, electricity generator, and blower/fan, connected to a single shaft. The working involves installing the system in the exhaust to capture pressure energy from gases to rotate the shaft and generator, producing electricity while also improving engine performance and power. Advantages include low cost electricity production and improved engine output, while disadvantages are potential choking of the turbine and currently low electricity output. Applications proposed are for powering devices in vehicles and charging batteries to enhance vehicle efficiency.

3. INTRODUCTION
1. 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.
2. 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.

6. Working/Operation
 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.

8. Guide Vanes
 Guide vanes are very important part in two stage turbine.
 It will allows the gases from one turbine to another turbine.
 These guide vanes helps to convert maximum kinetic energy into
mechanical work.
Electricity Generator
•This generator convert the mechanical work into electrical energy
•This generator is also a DC motor of 12 volt 0.5 MA current
•This DC motor will give maximum output on 300 rpm.

9. Advantages/Disadvantages
Advantages
 It is an very economical setup.
 Engine performance and electricity generation.
 The electricity can be used in electrical equipments in the vehicles and
to charge the battery.
 Engine power and performance is also improving by this mechanism.
Disadvantages
 Due to carbon emission the turbine can be choked earlier
 Electricity generator producing low electricity but it can be improve
by using voltage multipliers.

10. Application
 In automobile vehicles like- cars, trucks and bikes also.
 In Automobile vehicles to charge the mobile phones like in bike.
 This mechanism use in all types of engine
