Performance studies on non-edible oil as IC engine fuels: A review

Petroleum fuels have served mankind successfully for more than a century mainly for mobility in the form of vehicles, power generation and industrial activities. As crude oil is a fossil fuel, we cannot rely upon it forever. Transportation is the backbone for the mobility for which fuel is the basic necessity. As the petroleum products are at the verge of their extinction, finding alternative fuels is the need of the time. Alternative fuels are obtained from seeds of many edible and non-edible oil plants. Edible oils due to their consumption for cooking purposes, may not be advisable to use for commercial activity, however, non-edible oils can be attempted as a source to serve the purpose as engine fuels. Non-edible oils can be blended with the petroleum products and can be used mainly in the diesel engine with slight or no modifications. The performance studies are being carried out by various researchers all over the world using many such refined oils as engine fuels. This review paper attempts to collate the published research literature. The focus in this review paper is on analysis of availability, engine performance and pollution characteristics when oils such as Jatropha curcas, Calophyllum inophyllum, Mahua and Pongamia pinnata are used. © 2019 Technoscience Publications.
