Propane: The Alternative Fuel for Transportation

Propane has been considered as an alternative energy source for decades due to its relatively clean-burning properties. It stems from domestic petroleum and is primarily composed of propane and butane. Propane is stored in a pressurized tank as a liquefied gas, which is then onboard a vehicle for transportation. The pressure inside the tank keeps the propane in a liquid state, and when inflated, it can hold up to 300 pounds per square inch.

Propane Fuel Consists of Gaseous and Liquid States

Propane fuel consists of both gaseous and liquid states. When the tank is pressurized, the propane remains in a liquid state. However, when the pressure is released, the propane turns into a gaseous state, which is used to power the engine. Propane has a high octane rating of 104, which prevents engine knocking and increases the British thermal unit (BTU) output.
