WHAT IS LPG?
LPG is Liquefied Petroleum Gas
Mixture of Propane C3H8 and Butane C4H10
Butane and Propane are products of petrol
Liquefies easily. Good for fuel

WHERE DOES IT COME FROM?
LPG is from two different sources
It occurs naturally in oil and gas fields
Also a by-product of oil refining

SUITABILITY AND PERFORMANCE
Performance of LPG vehicles better than other
alternate fuels
Has a higher octane rating than gasoline
Runs smoother, less maintenance needed
Releases less soot than gasoline and diesel
Better thermal efficiency

AVAILABILITY AND SUPPLY
LPG gas liquefies under a pressure of only 7
bars, therefore can fit a lot of energy in a
small space. Tanks can be smaller and cheaper.
Around 60 of the world supply of LPG comes from
separation of natural gas, 40 is from refinery.
Its supply is at least as secure as petrol and
diesel. Certainly not less than 50 years

ENERGY DENSITY
LPG has a lower energy density than gasoline and
diesel. Although this has no effect on engine
performance, it does mean that a larger volume of
fuel and a bigger tank are required to achieve
the overall driving range.

ENGINE CONVERSION
Although vehicles can now be purchased already
running of LPG, major vehicle manufacturers
including
FORD VAUXHALL VOLVO ROVER
Many vehicles are converted after being sold
Conversion can be relatively straight forward
although with modern management systems and
liquid injection the cost is around 1600 for a
car or light van.
Diesel engines are more complex to convert, as
the compression ratio has to be altered.

STORAGE AND DISTRIBUTION
LPG vehicle tanks are constructed from carbon
steel and 20 times more puncture resistant than a
typical gasoline, methanol or ethanol tank.
New LPG cylinders are manufactured with a device
that shuts off the filling process when the tank
reaches 80 of its liquid capacity, allowing for
temperature changes in fuel volume without any
release of gas

SAFETY
LPG in this form is an especially safe for
vehicle applications

• LPG engine fuel systems are fitted with safety
  valves which are automatic if fuel line ruptures.

• LPG is non-toxic, non poisonous and doesnt
  contaminate soil

• LPG has lowest flammability of any alternative
  fuel.

• LPG wont ignite with air unless ignition is at
  940F. Gasoline needs only an ignition of 430F.

• If LPG leaks it doesnt puddle but evaporates

15
ENVIRONMENT
LPG is an outstanding fuel for vehicles that must
comply with increasing emission requirements.
This has enabled LPG to outscore conventional
fuels and alternatives.
Among the lowest life-cycle greenhouse gas
emissions of all commercially available fuels.
COMPARED TO GASOLINE, LPG YIELDS

• 50 less CO

• 40 less CxHx

• 12 less CO2

• 35 less NOx

• 50 less ozone forming potential
