Introduction

Liquefied Petroleum Gas (LPG) has been used as an automotive fuel in Australia since the 1960s. LPG is the generic name for mixtures of hydrocarbons (mainly propane and butane) which, when lightly compressed, change from a gaseous state to a liquid. It is readily available, either as a naturally occurring constituent of underground gas and petroleum fields or as a product of
petroleum refining. In the former case the propane and butane is separated from other naturally occurring gases, such as methane (CNG).

LPG is a plentiful, clean burning and easily stored alternative to traditional diesel and gasoline (petrol) fuels, but until recently its use has been restricted to aftermarket
conversions of vehicles originally manufactured to run on petrol. It may have spent a long time in adolescence, but in the new millennium LPG is poised to deliver its true potential as a
mainstream automotive fuel.

This fundamental change will be characterised by a transition from automotive LPG’s "cottage industry" image, to a commercial environment in which it is
embraced by the major vehicle manufacturers as a fuel of choice, actively sought by a rapidly growing number of new vehicle buyers.
