What is LPG fuel?
LPG stands for Liquefied petroleum gas, which basically means that when it is stored under pressue it is a liquid, but when being burnt in an internal combustion engine it evaporates into a gas. It is useful in cars as it is non-toxic, non-corrosive and doesn t require any additional compounds to prevent knocking (Lead in petrol used to do this, and other compounds such as benezene in Unleaded petrol are still used).
