AutoGas (LPG) is a clean, high octane, abundant and eco-friendly fuel. It is obtained
from natural gas through fractionation and from crude oil through refining. It is
a mixture of petroleum gases like propane and butane. The higher energy content
in this fuel results in a 10% reduction of CO2 emission as compared to MS.
AutoGas is a gas at atmospheric pressure and normal temperatures, but it can be
liquefied when moderate pressure is applied or when the temperature is sufficiently
reduced. This property makes the fuel an ideal energy source for a wide range of
applications, as it can be easily condensed, packaged, stored and utilised. When
the pressure is released, the liquid makes up about 250 times its volume as gas,
so large amounts of energy can be stored and transported compactly.
The use of LPG as an automotive fuel has become legal in India with effect from
April 24, 2000, albeit within the prescribed safety terms and conditions. Hitherto,
the thousands of LPG vehicles running in various cities have been doing so illegally
by using domestic LPG cylinders, a very unsafe practice. Using domestic LPG cylinders
in automobiles is still illegal.
The fuel is marketed by IndianOil under the brand name ‘AutoGas’
"IndianOil has setup 350 Auto LPG Dispensing Stations (ALDS) covering 192 cities
AutoGas impacts greenhouse emissions less than any other fossil fuel when measured
through the total fuel cycle. Conversion of petrol to AutoGas helps substantially
reduce air pollution caused by vehicular emissions.
The saving on account of conversion to AutoGas in comparison to petrol is about
35-40%. Low filling times and the 35-40% saving is a reason enough for a consumer
to convert his vehicle to AutoGas.
