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)

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

• The Characteristics of Ethanol are the following:

–Environmental friendly–Renewable Fuel Source–Can be blended with other fuel sources –(Donal, 2000)

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?

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?

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

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)

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)

“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)

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)

“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)

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)

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)

“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)

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)

It has a high octane rating, result in increased engine efficiency

and performance. (Chevron,2005)

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)

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

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.

• 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.
