What types of fuel are there?

Explanation:
In aviation, fuels are matched to engine types. Piston-engine aircraft run on aviation gasoline (avgas), with high-octane grades like 100LL to prevent knocking. Turbine-engine aircraft—the jets and many turboprops—use jet fuel, typically Jet A or Jet A-1, which is kerosene-based and suitable for turbines. Since aviation includes both piston and turbine powered airplanes, the field uses both avgas and Jet A. Diesel engines exist in some designs, but they are not the standard for most aircraft, so the typical, broad answer is that both types are used.
