Abstract
The depletion rate of conventional petroleum fuels is very fast. Gasoline is used as conventional fuel in the SI engine. Emissions from this fuel cause environmental pollution because it produces harmful emissions for the environment such as CO2, CO, HC, and NOx. Liquefied petroleum gas (LPG) has physical and chemical properties that make it a favorable fuel for IC engines. It can be used as a fuel alone or combined with gasoline with some minor engine modifications. The engine running on LPG showed improved performance - in terms of fuel economy, overall efficiency compared to petrol. In addition, it is noted that LPG emissions are greatly lower than petrol. This work reviews the research conducted by previous researchers on LPG-powered SI engines under several working conditions.
