Ethanol Alcohol and its Effects on Gasoline

based on 8 ratings
Author: Robert S.

2011 VIRTUAL SCIENCE FAIR ENTRY

Abstract

Purpose: The purpose of my project is to see if adding higher levels of ethanol alcohol to gasoline decreases the run time of a motor.

Procedure: Carefully add 50 millimeters of 87 octane gasoline blended with 10% ethanol alcohol to the empty fuel tank of the motor and measure how long the motor runs for. Repeat this for both 89 and 93 octane gasoline. In a fifty millimeter measuring cup mix 45 millimeters of gasoline and 5 millimeters of ethanol alcohol, then add this mixture to an empty fuel tank and measure how long the motor runs for. Repeat this for both 89 and 93 octane gasoline. Keep repeating these steps until you can measure up to 50% ethanol alcohol and 50% gasoline.

Conclusion: In conclusion, my hypothesis was proved correct that, adding higher levels of ethanol alcohol decreases the run time of a motor.

Safety Issues

In my experiment there are the following safety errors, working with gasoline and ethanol. Because, you are working with such dangerous liquids you must take certain safety precautions. You must always make sure that there is nothing flammable nearby you experiment area, and you must make sure that you are wearing a mask so that you do not breathe in any fumes. In this experiment you also work with a motor, so you must be careful not to do anything that would compromise the safety of the motor, or compromise your own safety.

Time Taken to Complete Project

Altogether my project, took me around 10 hours to complete. This is because it took me around four hours to set up my experiment, as well as to do a pre trial run with my experiment. It took me around 3 hours to do the actual experiment, and around three hours to do my results, as well as research.

Objective

The purpose of this experiment is to see if adding higher levels of ethanol alcohol to gasoline, will improve the run time of a motor.

Materials

  1. 4 Cycle internal combustion motor, 3.5 horse power made by Honda – Home Depot
  2. Stop Watch – Home Depot
  3. Fire Extinguisher -- Home Depot
  4. 87 Octane gasoline blended with 10% ethanol alcohol – Quick Trip
  5. 89 octane gasoline blended with 10% ethanol alcohol – Quick Trip
  6. 93 octane gasoline blended with 10% ethanol alcohol – Quick Trip
  7. Pure Ethanol alcohol – Can Only be Produced not Purchased
  8. Measuring cup in metric units – Wal-Mart

Most of the items used in my experiment were easy to obtain, the only item that was not easy was the Pure Ethanol Alcohol. The reason for this is because it is extremely hard to buy it, in my cases you have to produce it yourself.

Introduction

When people think of gasoline, most people would think about cars or some other uses of gasoline. It can be said that gasoline makes the world “go around”. Whether you believe that saying or not, it cannot be doubted that gasoline affects everyone. Gasoline is not a renewable resource. Because gasoline is not renewable, ethanol is starting to be added to gasoline. Ethanol, which is renewable, has many uses to help gasoline, like helping it run in an internal combustion engine. Ethanol has many uses not only because it is renewable, but it gives gasoline unique properties that improve its use. While ethanol does help gasoline, adding large quantities of ethanol to gasoline decrease gasoline’s potential.
