LPG stands for Liquefied
Petroleum Gas, when used as a road fuel it is
often known as Autogas. It is the third
mainstream fuel for vehicles and is a cheaper
alternative to petrol. LPG is a natural gas
resource and is also a by-product of oil
production. At atmospheric pressure it is a
vapour, under modest pressure it becomes liquid.
When used as a fuel in
spark ignition vehicles, i.e. petrol engines,
Liquefied Petroleum Gas is usually branded as
Autogas or LPG.
The calorific value of gas
is slightly greater than petrol but the density
is around 15% less than petrol. Using it as an
automotive fuel to replace petrol will result in
a comparable drop in MPG, BUT this will be more
than compensated for as the average price of LPG
is less than half the cost of petrol, resulting
in half cost motoring.
Normally when a vehicle is
converted to LPG the petrol system remains
intact so that it can be used on either fuel
thus providing an increased driving range on
dual fuel where necessary.
LPG is one of the cleanest
vehicle fuels available, and with over 4 million
cars worldwide now running on LPG, it is fast
becoming a popular choice both for its
environmental benefits:
LPG is better for your
vehicles engine as it is a clean burning fuel,
which leaves fewer deposits in the car engine
Better for budgets -
better for the environment. LPG is the cleaner
fuel for a cleaner future.
Due to a smaller molecular
size LPG burns cleaner than petrol. This leads
to a reduction in all the usual emissions. In
particular, the main greenhouse gas Carbon
Dioxide is significantly reduced.
According to research, LPG
vehicles emit 20% less carbon dioxide than their
petrol counterparts . Carbon dioxide, nitric
oxides and particulates (soot) are key
contributors to problems like poor air quality
and global warming.
It would also take around
20 LPG cars to produce as much nitric oxides as
is pumped out by just one diesel-powered car!
The particulates that we
see coming from diesel vehicles cause over
20,000 premature deaths a year. LPG produces 90%
less particulates than a diesel engine.
Noise from LPG powered
engines is quieter than from diesel engines,
keeping sound pollution to a minimum.
