Introduction:

Propane or liquefied petroleum gas (LPG) is a clean-burning fossil fuel that can be used to power internal combustion engines.

Features of LPG:

LPG-fuelled vehicles produce fewer toxic and smog-forming air pollutants. Petrol (gasoline) and diesel vehicles can be retrofitted to run on LPG in addition to conventional fuel. The LPG is stored in high-pressure fuel tanks (Fig. 2.310), so separate fuel systems are needed in vehicles powered by both LPG and a conventional fuel.

Advantages:

● fewer toxic and smog-forming air pollutants

● less expensive than petrol.

Disadvantages:

● no new passenger cars or trucks commercially available, but vehicles can be retrofitted for LPG

● less readily available than conventional fuels

● fewer miles on a tank of fuel.
