Read Clean fuels: an overview, then answer the following questions.
| OK |
1) What is a common disadvantage of switching to clean fuels for vehicles?
Higher fuel cost and lower vehicle range.
| OK |
2) What is the most overwhelming common advantage of switching to clean fuels?
The lower emissions compared to gasoline.
| OK |
3) Does this article really answer whether clean fuels are feasible?
It sort of does but it really doesn't. It bascially states that in the future clean fuels will be more feasible, but right now it's not very feasable.
Read about alternative fuels at the AFDC. Pay close attention to the section Compare Alternative Fuel Properties, then answer the following questions:
| OK |
4) List the fuels on the Comparison chart by octane rating, from lowest to highest: 1. Electricity (N/A) 2. No. 2 Diesel 3. Biodiesel 4. Gasoline 5. Ethanol 6. Methonal 7. LPG 8.LNG 9.CNG 10. Hydrogen
| OK |
5) Which alternative fuel has the most diversity to date for types of vehicles?
CNG
| OK |
6) Rank the all the fuels on the chart by their energy content from highest to lowest: 1. No. 2 Diesel 2. Gasoline 3. Biodiesel 4. LPG 5. Ethanol 6. LNG 7.Methanol 8. CNG 9. Hydrogen 10. Electricity (N/A)
| OK |
7) Gaging by the chart, what seems to be the safest fuel?
| OK |
8) Do you have any way of gaging whether this chart was accurate or not? How would you go about finding out if it is true or not?
There really isn't anything that stands out on this chart to confirm it is accurate. The chart is well put together and is detailed, which suggests it's accurate.
If I wanted to find out if the chart was accurate or not I would research and try and find indipendent studies on each of these types of fuel and compare them to the chart. Also I'd find where this chart was formed and with what studies and information. *Also read Alternative Fuel Driver Training: Companion Manual for Monday.
