Liquefied petroleum gas (LPG), also known as propane, is a nonrenewable gaseous fossil fuel, which turns to liquid under moderate pressure. LPG, a by-product of natural gas processing and oil refining, includes various mixtures of hydrocarbons. The type of LPG used as a vehicle fuel is a liquid mixture containing at least 90 percent propane, 2.5 percent butane and higher hydrocarbons, and the balance ethane and propylene. The mixture is commonly called "propane."
Power, acceleration, payload and cruise speed are comparable to those of an equivalent internal combustion engine. Propane has a high octane rating of 104 (compared with 87 for regular unleaded gasoline.) |
