2. Introduction
• Ethanol, also known as ethyl
alcohol, has the chemical formula
C2H5OH. It is the same alcohol
found in alcoholic beverages, but
ethanol also makes an effective
motor fuel. (Walker, 2010)

3. • There have been decades of motor
fuel application experience in the
United States and other countries
with ethanol.(Walker, 2010)

4. • The Characteristics of Ethanol are
the following:
–Environmental friendly
–Renewable Fuel Source
–Can be blended with other fuel
sources
–(Donal, 2000)

5. Significance of the Study
• General Public
• Researchers

6. Statement of the Problem
 This paper primarily aims to
determine the challenges and demands
of Ethanol-Powered Vehicles.
 Specifically, it seeks to answer the
following questions:
1. What are the significant benefits of
ethanol-powered vehicles?

7. 2. What are ethanol’s characteristics as
a motor fuel?
3. How does it work?
4. What are the Challenges of using
Ethanol-Powered Vehicles?

8. 5. What are the potentials of Ethanol-
Powered vehicles?

9. Thesis Statement
The ethanol powered cars use
ethanol or ethyl alcohol as the
fuel for running the vehicle.
Ethanol fuel is a biodiesel
alternative to gasoline.
(Smith & Workman, 2014)

10. As ethanol is easy to manufacture,
the ethanol powered cars gained
good wide acceptance in the green
car market. (Magon, 2014)
Ethanol powered cars are eco
friendly and deliver power at good
fuel efficiency. (Mueller, 2010)

11. “Significant Benefits”
According to the American Coalition
for Ethanol(advocacy group),it reduces
harmful emissions of carbon monoxide.
Ethanol is good for the economy.
Ethanol production supports farmers
and creates domestic jobs.
(Magon, 2014)

12. Ethanol helps reduce imported oil
and greenhouse gas emissions.
Like any alternative fuel, there are
some considerations to take into
account when contemplating the
use of ethanol. (Magon, 2014)

13. “Characteristics”
The use of ethanol as a motor fuel for
internal combustion engines, either
alone of in combination with other
fuels. (Magon, 2014)
Ethanol can also be used to power fuel
cells and to produce biodiesel,
increasingly used as an oxygenate
additive for standard gasoline (Magon,
2014)

14. Ethanol used as motor fuel offers a
way to reduce greenhouse gas
emissions from transportation sources.
(Magon, 2014)
It will be just the same as using pure
gasoline. Since most modern
commercial vehicles are already
designed to accept ethanol as a fuel
additive (Magon, 2014)

15. With respect to other motor
vehicle emissions, differences
between ethanol and gasoline are
becoming less significant as new
motor vehicles are produced with
extremely low emission levels on
all fuels. (Magon,2014)

16. “Performance and How it
works”
They work on the same principles of
internal combustion engines that was
designed and built by car manufacturer
of the world. (Magon, 2014)
The ethanol fuel consumption in car
engines is more than that in gasoline
engines but increased performance.
(consumerenergycenter.org/transportation
/afvs/ethanol.html)

17. power output and better fuel economy
is achieved in an ethanol fuelled car
engine through higher compression
ratios. (Parkash,1998)
The ethanol powered engines deliver
more torque than the gasoline powered
engines.(Parkash,1998)

18. It has a high octane rating, result
in increased engine efficiency and
performance. (Chevron,2005)

19. Challenges and
Potentials :Interview

20. Challenges and
Potentials
There’s a problem when we use it as a
100% fuel. It can run, it’s okay, but
because of the slower heating value it
will take a lot more time for it to
perform well. (Magon,2014)

21. With the demand, we will see
more ethanol in the future because
this is a renewable product.
(Magon, 2014)

22. Conclusion
• According to the researchers, ethanol can be blended with other
fuels and it is also eco friendly, so therefore we conclude that
ethanol has more potential and is strongly recommended to be a
fuel of a powered vehicles.
• Although there are some things that you might be thinking that
somewhat it can’t be a fully fuel but we think that in our next
generation we can see that there are 100% ethanol fuel not totally
but mostly of it.
• Ethanol is cheaper than other fuels. Ethanol has many benefits and
positive sides that we can agree to buy ethanol powered vehicles
and use them. As we were saying is that people who is eco- friendly
and loves cars will be interested in this one.
• Ethanol offers much more value than it is traditionally given credit
for, as far as improving efficiency and reducing emissions.

23. • An important study by Ricardo Engine Consultants, entitled Technical
Assessment of the Feasibility of Introducing E15 Blended Fuel in the US
Vehicle Fleet, 1994 to 2000 Model Years, September 2010, concluded that
with reasonable certainty "The analysis concluded that the adoption and
use of E15 would not adversely affect fuel system components in properly
engineered vehicles, nor would it cause them to perform in a sub-optimal
manner, when compared to the use of E10.
• Vehicles running on ethanol will generate higher concentrations of ozone
than those using gasoline, especially in the winter.
Researchers have found that could create new health concerns in areas
where ozone hasn't been a significant problem before.
So Ethanol -- often promoted as a clean-burning, renewable fuel that
could help wean the nation from oil -- would likely worsen health
problems caused by ozone, compared with gasoline.
