LIQUEDFIED PETROLEUM GAS

LPG:

 

Autogas is the common name for liquefied petroleum gas (LPG) when it is used as a fuel in internal combustion engines in vehicles as well as in stationary applications such as generators. It is a mixture of propane and butane.

Autogas is widely used as a "green" fuel as it decreases exhaust emissions. In particular, it reduces CO2 emissions by around *5% compared to petrol. One litre of petrol produces 2.3 kg of CO2 when burnt, whereas the equivalent amount of autogas produces only 1.5 kg of CO2 when burnt.[1] It has an octane rating (MON/RON) that is between *0 and **0 and an energy content (higher heating value—HHV) that is between *5.5 megajoules per litre (for pure propane) and *8.7 megajoules per litre (for pure butane) depending upon the actual fuel composition.

Autogas is the third most popular automotive fuel in the world, with approximately *6 million of **0 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 ascending order): Turkey, South Korea, Poland, Italy, and Australia.
