The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
The main fuel source for the work of the cell is the mitochondria.

The jet engines used jet fuel, not gasoline as the 6 main engines did.
Airplanes primarily use jet fuel as their main source of energy to power their engines. The combustion of jet fuel in the engines creates high temperatures and gas flow that propel the aircraft forward.
coal was the main source at that time
Unleaded fuel is used in gasoline engines, while diesel fuel is used in diesel engines. The main difference is in how the engines ignite the fuel - gasoline engines use spark plugs, while diesel engines use compression to ignite the fuel. Diesel fuel also has a higher energy density than unleaded fuel.

The main source of locomotive engine fuel historically was coal, which was used in steam locomotives to generate steam for powering the engine. As technology advanced, diesel fuel became the primary energy source for diesel locomotives, offering greater efficiency and power. In recent years, there has been a growing interest in alternative fuels like electricity and biofuels to reduce environmental impact.
Petroleum is the main source of energy for transportation.
