Autogas, also known as liquefied petroleum gas (LPG), is a fuel used in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane, and it is composed of three parts carbon and eight parts hydrogen, making it a highly efficient, low carbon producing fuel. Autogas is widely used as a "green" fuel, as its use reduces CO2 exhaust emissions by around 15% compared to petrol. CO emissions are 30% lower, compared to petrol and NOx by 50% .
Autogas is the third most popular automotive fuel in the world, with approximately 16 million of 600 million passenger cars powered using the fuel, representing less than 3% of the total market share. Approximately half of all autogas-fueled passenger vehicles are in the five largest markets (in descending order): Turkey, South Korea, Poland, Italy, and Australia.
Autogas is produced as a by-product of natural gas processing and crude oil refining. Over ninety-nine percent of autogas is produced in America, increasing energy security by reducing America’s dependence on foreign oil. Propane is stored as a liquid in a relatively low-pressure tank and travels along a fuel line into the engine compartment. Autogas is an approved, alternative clean fuel listed in the 1990 Clean Air Act and National Energy Policy act of 1992.
Autogas is a safe alternative fuel that is non-toxic, non-corrosive, and insoluble in water. Fuelling with Autogas is as safe and simple as filling up with any other fuel. Autogas is a clean-burning fuel that produces fewer harmful emissions than gasoline. In fact, autogas is listed as a clean-burning fuel in the Clean Air Act of 1990 and the Energy Policy Act of 1992. Propane has a high octane rating, making it an excellent choice for spark-ignited internal combustion engines. If spilled or released from a vehicle, it presents no threat to soil, surface water, or groundwater.
In summary, autogas is a fuel used in internal combustion engines in vehicles and stationary applications such as generators. It is a mixture of propane and butane and is widely used as a "green" fuel. Autogas is produced as a by-product of natural gas processing and crude oil refining, and it is a safe and clean-burning fuel that produces fewer harmful emissions than gasoline.
