3 alternatives gasoline for automobiles?

Question

i need help on that one

Answer 1

Hydrogen, Ethanol, and Bio-Diesel, all three are still in the planning stages. I would suggest regular Diesel, Propane, and Hybrids (sure, Hybrids still use gas, but they use a lot less.)

Answer 2

Since you specified gasoline, I won't list diesel - a gas motor is not easily converted to diesel (just ask GM). For an existing gas motor, propane is the simplest alternative, a conversion runs 2-3 thousand and fuel is available almost everywhere in North America. Next is compressed natural gas (CNG), which is somewhat more expensive to convert and has limited availability. E85 (85% ethanol/15% gasoline) is becoming available, but your fuel system has to be designed to use it.

Hydrogen is still in the development stages. If hydrogen fuel cell cars are made available to the public in the next decade, they will probably still use gasoline as a fuel source, since there is no practical way of storing elemental hydrogen in an on-board fuel tank, and the amount of energy required to get the hydrogen out of water is more than any potential fuel economy savings. Gasoline is a good source of hydrogen and isn't difficult to crack through a generator cell to get hydrogen and CO2. Still creates greenhouse gases though

Answer 3

Each gasoline grade is associated with an octane rating, which you'll see on those yellow stickers at the pump. In North America, regular gas is equivalent to an octane rating of 87; mid-grade with 89; and premium with 91. In some states, particularly those with a higher elevation, you may find what's sometimes called an "Economy" grade, which is lower than 87. At the other end of the spectrum, you'll often see premium gas with an octane rating as high as 95, depending on the gas company you get your fuel from. but...basically they measure the fuel's resistance to detonation, or the premature ignition of the fuel/air mixture during the engine's compression cycle. if you car does not specifically say it needs the premium rated gasoline...its more cost efficient to just use regular or mid-grade.
