With the vitality and economic growth of the U.S. being linked to affordable transportation, the use of alternative fuels is beginning to play a larger role. The use "alternative fuel" has been used to describe any fuel suggested for use in transportation vehicles other than gasoline or diesel. Since 1998, more than half of the petroleum the U.S. economy requires has been supplied by imports. In addition, the climatological and scientific community has warned that increasing concentrations of greenhouse gases in the atmosphere will cause global change. Alternative Fuels examines the accepted alternative fuels, providing historical background, physical and chemical properties, production technology, and forecasts for each fuel. Alternative transportation fuels addressed include: methanol, ethanol, propane, natural gas, biodiesel, hydrogen, and electricity. Chapters include: The Argument for Alternative Fuels Methanol Ethanol Propane Natural Gas Electricity and more

Homogeneous Charge Compression Ignition (HCCI) engines can have efficiencies as high as compression-ignition, direct-injection (CIDI) engines (an advanced version of the commonly known diesel engine), while producing ultra-low emissions of oxides of nitrogen (NOx) and particulate matter (PM). HCCI engines can operate on gasoline, diesel fuel, and most alternative fuels. While HCCI has been demonstrated and known for quite some time, only the recent advent of electronic sensors and controls has made HCCI engines a potential practical reality. This paper provides a comprehensive overview of the current state-of-the-art in HCCI technology, estimates the potential benefits HCCI engines could bring to U.S. transportation vehicles, and lists the R&D barriers that need to be overcome before HCCI engines might be considered for commercial application.

This book presents the fundamentals needed to understand the physical and chemical properties of alternative fuels, and how they impact refueling system design and the modification of existing garages for safety. It covers a wide range of fuels including alcohols, gases, and vegetable oils. Chapters cover: Alternative Fuels and Their Origins Properties and Specifications Materials Compatibility Storage and Dispensing Refueling Facility Installation and Garage Facility Modifications and more
