they can't use gasoline fuel only aviation fuel
No, "jet fuel" refers to a set of fuels used in gas turbine engines (GTE). Gasoline would burn far too hot in a GTE, eventually damaging the engine. Jet fuel is a lot closer in nature to Diesel, Parafin or Kerosene
Jet fuel is capable of polluting, just as gasoline is.
Jet fuel is diesel fuel, which is generally cheaper than high-octane gasoline.
Jet fuel is basically kerosene, a petroleum product like gasoline.
av gas; i.e. aviation gasoline. Jet fuel.
Gasoline or Jet 'A'
Gasoline, kerosene (jet fuel) and diesel fuel
While a 707 or any jet could run on gasoline for a period of time, jet engines run on jet fuel which is similar to kerosene or diesel fuel.
Jet fuel, literally <><><> Depends on the plane. Jet aircraft DO use jet fuel, which is mainly very pure kerosene. Piston engined aircraft use AVGAS- or Aviation gasoline- a high octane form of gasoline.
The compression ratios of jet engines are too high to accomodate gasoline - - - - - Two reasons. The most important is jet fuel is a light oil, which the manufacturers of fuel pumps are well aware of: the fuel pump on a jet engine is lubricated by this fuel. If you run gasoline through a jet engine you will destroy the fuel pump. The other is gas burns hotter than jet fuel, and will damage the engine. Having said that, jet engine owner's manuals allow you to burn gasoline for very short periods of emergency service...you're out of fuel, you're in the middle of the desert, bad people are on their way and the only fuel there is around you is gasoline. You can put some in, fly to where you need to go and drain the system immediately.
Petroleum
The jet engines used jet fuel, not gasoline as the 6 main engines did.
