A review of global current scenario of biodiesel adoption and combustion in vehicular diesel engines

Delving into the current chronicles of research findings, explorations of biodiesel production and utilization in diesel engines have been at the forefront of sustainable and creative energy discovery. Far beyond the problems of energy crises, renewable biodiesel offers unlimited solutions to the associated issues of depleting reserves and harmful emissions with fossil fuels. In overcoming the increasing energy demand owing to the growing worldwide population, the emergence of biodiesel and its global adoption in the transportation sector has brought along a reliable fuel supply that can be used in diesel engines without any modification. This study explores the comprehensive utilization of biodiesel as engine fuel and shows the prevalent global current adoption in automobiles engines. The production rates are documented globally and promoting policies that are being mandated in many countries of the world are discussed as well. The improved state of things in achieving effective power conversion from biodiesel combustion with minimal emission impact on the environment has been documented. Worldwide technological adoption has been captured according to production rate, usage and legislation favouring the economic feasibility of diesel engines that are suitable for biodiesel with little or no modification. With the progress made so far by many researchers to establish biodiesel as a viable engine fuel, coupled with the ability to eradicate environmental issues like global warming and sustainability, it is evident that biodiesel is designed to make a future energy investment and significant addition to the domestic and industrial automobile economy.
