ABSTRACT
Currently, a perfect deal of the efforts of the mechanical firm is concentrated on advancement on the general
vehicle ́s efficacy. Each kind of engine operates as heat engine. This engine operates by converting chemical
energy to thermal energy and when the motion of the piston is done on the heat pressure which carries air. This is
the reason why when starting a vehicle about 30% to 40 % of the energy. The amount of energy left is wasted just
as energy employed in cooling component and exhaust gases thus the efficiency is low. In this research paper there
are several kinds of methods that is employed in energy recovery as well as conversion of energy to electrical
energy to improve the operational efficiency. This paper examines the application of thermal generator for
production of energy. The generator (thermoelectric) generates waste gases steam and small Direct Current which

generates temperature as it operates. There are several coolant path of exhaust gas on impact of seebeck. From a
single module of thermocouple the output voltage ranges between 170 to 200 V for a range of temperature of 300
and 350C. The system will be capable to start the light emitting Diode, piezoelectric, mobile charger, Electronic
Flasher fuel saving and parking Horns.
Keywords: Booster Circuit, Thermoelectric generator, Exhaust gases, internal combustion engine and Temperature
of the exhaust gases.

CHAPTER 1: INTRODUCTION
• Heat engine: This is a type of engine which operates through conversion to mechanical work output from
thermal energy. Example of this involve the engine of diesel, engine of petrol and steam engine.
• For the working principle of the thermal energy to the operating fluid of the heat engine, the classification of
the heat engine as a combustion engine (CE) and an IC engine
• For an IC engine, the combustion occurs in an engine ́s working fluid therefore the fluid is polluted
with the product being combusted.
- A good example of the internal combustion engine is petrol engine, in this engine the working
fluid is a combination of air and fuel.
• For an EC engine burning fuels (fossil) is employed as a working fluid, such systems do not have a
direct contact with a combustion materials.
- A good example of EC engine is a steam engine and steam is the working fluid.
Internal combustion engines may be classified as:
- Compression Ignition engine
- Spark Ignition engine
• Combustion engine CI): In this type of engine the combustion process commenced at a point where the
