Module 3: Economics

Check: 1. X 6. X 11. 2. X 7. X 12. 3. 8. X 13. X 4. X 9. X 14. X 5. 10. X 15. Essay: 1. Increases farm income, boosts employment, improves balance of trade, adds to tax receipts, results in a net savings to the federal government, less dependence on foreign oil. 2. The increase in corn prices are offset by the production of cattle feed during the making of ethanol. While it is possible that meat & milk prices might increase slightly, it is doubtful.

Module 4: Environment

Matching: 1. D 2. B 3. E 4. C 5. F Essay: 1. Ethanol and other oxygenated fuels take the place of some of the gasoline and adds oxygen to the combustion process which reduces levels of all pollutants controlled by the EPA. Project Answers: 1. ETHANOL 12. OXYGEN 2. OCTANE 13. SUBSIDY 3. GASOLINE 14. OIL 4. CARBON MONOXIDE 15. DEHYDRATE 5. EMISSIONS 16. BRAZIL 6. GRAIN 17. FARMER 7. CORN 18. FUEL 8. ALCOHOL 19. HYDROCARBONS 9. OZONE 20. UNLEADED 10. ENERGY 21. INCENTIVE 11. ENHANCER

Module 5: The Fuel

True / False: 1. Fuel extender 6. 85% 2. Octane booster 7. Brazil 3. True 8. True 4. 40% 9. Ethanol 5. True 10. True Multiple Choice: 1. C 2. E 3. B 4. B 5. A Fill in the Blank: 1. gasoline 6. 90 2. octane rating 7. methanol 3. pinging or knocking 8. 17% 4. volatility 9. 100% 5. 9 10. variable Essay: 1. Ignition timing, air fuel ratio, barometric pressure, temperature, humidity, combustion temperature, exhaust gas re-circulation rate, combustion chamber deposits. 2. Volatility too low causes: poor cold start, poor warm-up performance, poor cool weather driveability, increased crankcase, combustion chamber & spark plug deposits, or unequal fuel distribution. Volatility too high causes: vapor lock, loss of power, rough running or stalling, decreased fuel mileage, increased evaporative emissions, or fuel evaporation canister overload. 3. Reduced emission levels, especially hydrocarbons & carbon monoxide (use of ethanol made from corn increases amounts of corn grown which increases the conversion of carbon dioxide into oxygen, which combats global warming).
