LPG
LPG is the generic name for commercial propane and commercial butane. These are hydrocarbon products produced by the oil and gas industries.
Commercial Propane predominantly consists of hydrocarbons containing three carbon atoms, mainly propane (C3H8).
Commercial Butane predominantly consists of hydrocarbons containing four carbon atoms, mainly n- and iso - butanes (C4H10).
Both Propane and Butane become liquid at ambient temperature if moderately compressed, and revert to gases when the pressure is sufficiently reduced. Advantage is taken of this property to transport and store these products in the liquid state, in which they are roughly 250 times as dense as they are as gases.

LPG is used as a fuel in positive (spark) ignition engines, which can be specifically tuned for LPG or run as bi-fuel engines with Gasoline and LPG, using a fairly simple switch-over device. Because of its relatively high Hydrogen content it produces less CO2 (and more H2O) than Gasoline which has a higher proportion of Carbon. It also burns at a lower temperature and so generates less NOx.
