Environmental Concerns and Potential Replacement of Petroleum Fuels: A Review

Mechanical

In the recent past, the crude oil prices have been increased immensely as the fossil fuels are depleting, biodiesel has emerged as an alternative fuel for the petroleum. The research is also going on for getting high thermal efficiency and low engine emissions. This expectation requires modification in both aspects i.e. in engine as well as in fuel. There is another issue of waste accumulation and its disposal. There are many kinds of waste which can be converted into useful form of energy and can be utilized for many applications. Many research investigations have been proved that biodiesel an attractive substitute to diesel fuel due to its renewable in nature and easy adoption in diesel engine. Also the choice of fuel has also been shifting from fossil fuel to biodiesel and fuel obtained by utilizing waste material. This research article attempts to provide an over view on various aspects of alternative fuel obtained by waste material and their implications on engine combustion, performance and emission
