The document discusses various alternative fuels to conventional fossil fuels. It introduces ethanol, methanol, vegetable oils, biodiesel, hydrogen, compressed natural gas, and electricity as some of the major alternative fuel types. For each fuel, it provides a brief overview of what it is, how it can be used as a motor fuel, and some of its advantages and disadvantages compared to gasoline or diesel. The overall purpose is to educate about alternative fuel options and their potential to reduce pollution and reliance on depleting fossil fuel reserves.

INTRODUCTION
Conventional Fuels:-
 Fossil fuels (petroleum), coal, and nuclear materials such as
uranium.
Alternate Fuels:-
 Also known as non-conventional fuels’
 Highly Oxidized, Sulphur Free, Environmental Friendly
 Any materials or substances that can be used as fuels, other
than conventional fuels
 Example:- Alcohol Fuel, Vegetable Oil,Biodiesel,Natural gas

WHY WE CHOOSE ALTERNATE FUEL
 Conventional Fuels are going to run out
 To reduce pollution
 To protect against Global Warming
 To save money
 Biodegradable and non-toxic
 Easy to handle and store
 Rural Development

DIFFERENT TYPES OF ALTERNATE
FUELS:-
 Alcohol fuels (ethanol & methanol)
 Water gasoline mixture
 Vegetable oil
 Biodiesel
 Hydrogen
 LPG & CNG
 Electricity
 benzol etc……

8. The first production car running entirely on ethanol was the Fiat
147, introduced in 1978 in Brazil by Fiat.
ETHANOL
Ethanol is a renewable, domestically produced alcohol fuel made
From plant material, such as corn, sugar cane, or grasses. Using
ethanol can reduce oil dependence and greenhouse gas (GHG)
emissions. Ethanol fuel use in the U.S. has increased dramatically
from about 1.7 billion gallons in 2001 to about 16.4 billion in 2016
Ethanol is also known as ethyl alcohol. It’s the alcohol in beer, wine,
rum, vodka, etc.
Ethanol was used to fuel some of the first automobiles…

9. Alternate fuels….
ETHANOL
 Alcohol-based alternative fuel produced by fermenting and
distilling starch crops or cellulose
 Most commonly used to increase octane and improve the
emissions quality of gasoline.
 Can be blended with gasoline to create E85, a blend of 85%
ethanol and 15% gasoline.(FLEX FUEL)
 An excellent, clean-burning fuel, has a higher octane rating
(over 100) and burns cooler than gasoline.
High ethanol blends present a problem to achieve
enough vapor pressure for the fuel to evaporate and spark the
ignition during cold weather

11. Chemical Formula: CH3OH , Density: 792 kg/m, Melting point: -97.6 °C
Methanol
Of all the fuel being considered as an alternate to gasoline,
methanol is one of the most promising and experienced
major research and development.
 Methanol, also known as wood alcohol, can be used as an
alternative fuel in flexible fuel vehicles that run on M85
 The benefits include lower emissions, higher performance, and
lower risk of flammability than gasoline
 Methanol can easily be made into hydrogen for hydrogen fuel cell
vehicles in the future.
 Methanol is extremely corrosive, requiring special materials for
delivery and storage.

12. VEGETABLE OIL
 RUDOLF DIESEL Designed a diesel engine in 1984 to run on
peanut oil.
 The use of vegetable oils for engine fuel may seem insignificant today. But
such oils may become in the course of time as important as petroleum an
coal tar products of the present time.
-An Extract from Diesel’s speech in 1912

13.  Most diesel car engines are suitable for the use of straight
vegetable oil (SVO), also commonly called pure plant oil (PPO),
with certain modifications. Principally, the viscosity and surface
tension of the SVO/PPO must be reduced by preheating it,
typically by using waste heat from the engine or electricity,
otherwise poor atomization, incomplete combustion
and carbonization may result. One common solution is to add
a heat exchanger and an additional fuel tank for the petrodiesel
or biodiesel blend and to switch between this additional tank and
the main tank of SVO/PPO. The engine is started on diesel,
switched over to vegetable oil as soon as it is warmed up and
switched back to diesel shortly before being switched off to
ensure that no vegetable oil remains in the engine or fuel lines
when it is started from cold again

14. BIODIESEL
 Biodiesel is a domestically produced, renewable fuel that can be
manufactured from vegetable oils, animal fats, or recycled
restaurant greases.
 Biodiesel is safe, biodegradable, and reduces air pollutants such
as particulates, carbon monoxide, hydrocarbons, and air toxics.
 Biodiesel can also be used in its pure form but it may require
certain engine modifications to avoid maintenance and
performance problems and may not be suitable for wintertime
use.
 Need to heat storage tanks in colder climates to prevent the fuel
from gelling

15. IMPORTANCE OF BIODIESEL
• Environmental friendly
• Clean burning
• Renewable fuel
• No engine modification
• Increase in engine life
• Biodegradable and non-toxic
• Easy to handle and store
• Complete CO2 cycle
• Sulphur free

16. FATTY ACID METHYL ESTER IS WELL KNOWN MOILECULE FOR VEGETABLE OIL.
 Fatty acid alkyl ester prepared from any oil or fat….
TRANSESTERIFICATION

17. NO FOSSILE CO2 RELEASED : NO GLOBAAL WARMING
 BIODIESEL CO2 CYCLE

18. Not occur free in nature in useful quantities,
but it is manufactured in a number of ways
HYDROGEN:-

19. •A potentially emissions-free alternative fuel produced from domestic resources.
Not widely used today as a transportation fuel
Advantages
 Emits only water vapour, assuming there is no leakage of
hydrogen gas
 It can store up to 3x as much energy as conventional
natural gas.
 Produced domestically.
 Environmentally friendly.
Disadvantages
 It still costs a considerable amount of money to run a
hydrogen vehicle
 Dangerous

20. It is much safer than other fuels in the event of a spill, because natural gas is lighter than
air and disperses quickly when released
 COMPRESSED NATURAL GAS

21. Advantages
 it can be efficiently and
safely stored.
 more environmentally
friendly due to its low
emissions after burning.
 most of the natural reserves
of natural gas field are
underutilized.
 Improve lubrication
because the cylinders are
not washed by petrol
excess
Disadvantages
 still does create greenhouse
gas emissions.
 highly volatile and can be
dangerous is handled or
transported carelessly.
 they aren't as roomy as
gasoline cars.
 higher overall costs of a
natural-gas vehicle
compared to a gasoline-
powered car.
