Fuels are substances, which, when burned or consumed, produce energy. Fuels in use today are mostly derived from petroleum. Fuels, which are not derived from petroleum, are known as alternative fuels, since they provide an alternative source of energy. Alternative fuels include natural gas, propane, hydrogen, biofuels, alcohol and other fuels. This book will serve as a complete reference for students of several disciplines like thermal engineering, automotive engineering, mechanical engineering, chemical engineering and energy studies and engineering, where alternative fuels is offered as an elective. It will also serve as a valuable reference for practicing engineers and scientists, working in similar field. Key Features — Provides detailed discussion on gaseous fuels, bio-fuels, synthetic fuels, reformulated conventional fuels and latest alternative fuel generation techniques — Includes additional features on alternative power trains and alternative fuel roadmaps
