What does Brazil use for automobile fuel?
Basiccaly the same as the other countries.
Brazil uses gasoline, GNV gas, and ethonal made from sugar cane (this kind of fuel, called Etanol, is starting to be exported for other countries, such as the United States, after an agreement made between the Brazilian and American government for the use of this fuel, that is less pollutant than those made with Petrol)
that's why Brazil developed the bi-flex technology for cars, making them able to use gasoline and alcohol in the same car.
Nowadays, there are already tri-flex cars in the streets. They work with three different fuels.
Not exactly. Petrol (called "gasoline" in the US) is made only from petroleum, the black crude oil which is pumped from the ground and is considered a fossil fuel. Maize (corn) can, however, be used to make ethanol, which automobiles can use to run quite effectively. Brazil is a nation which is converting its entire automobile fleet to use 100% ethanol as a fuel, although most of theirs is produced from sugarcane.
Small, general aviation type airplanes use avgas (aviation gasoline) which is very similar to automobile fuel. Large jet engines mostly use Jet-A fuel, which is a real nasty substance with a very high octane rating. Military fighter jets mostly use JP4 fuel which is similar to Jet-A but even more combustable.
make fuel filters that don't get eaten up by the bio fuel, and somehow burn the fuel so it gets better gas mileage. My experience with bio fuel is when we mixed in two extra gallons in a tank it burned two extra gallon by the time we fueled back up, in the same distance, and we had to rebuild several components in the engine.
