Clean Fuels: An Overview
1) What is a common disadvantage of switching to clean fuels for vehicles?
| OK |
There is a lower vehicle range and performance. There is also a higher vehicle cost.
2) What is the most overwhelming common advantage of switching to clean fuels?
| OK |
There are lower emissions of ozone-forming hydrocarbons and toxics.
3) Does this article really answer whether clean fuels are feasible?
| OK |
Somewhat, it talks about higher vehicle and fuel costs. The cost will rise with demand and there will be a limited supply.
Alternative Fuels
4) List the fuels on the Comparison chart by octane rating, from lowest to highest:
| OK |
8-15 No. 2 Diesel; ~25 Biodiesal; 86-94 Gasoline; 100 Ehanol(E85) and Methanol; 104 Liquified Petroleum Gas(M85); 120+ LNG and CNG; 130+ Hydrogen
5) Which alternative fuel has the most diversity to date for types of vehicles?
| OK |
CNG
6) Rank all the fuels on the chart by their energy content from highest to lowest:
| OK |
128,000-130,000 No. 2 Diesel; 109,000-125,000 Gasoline; 117,000-120,000 Biodiesel; ~84,000 Liquified Petroleum Gas; ~80,000 Ethanol (E85); ~73,000 LNG; 56,000-66,000 Methanol (M85); 33,000-38,000 CNG
7) Gaging by the chart, what seems to be the safest fuel?
| OK |
Hydrogen
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?
| OK |
Yes, I could research other website sources to find out if their findings agree with these.
