BIODIESEL: Cultivating Alternative Fuels

Combustion and Emissions Characteristics of Biodiesel Fuels

Modeling the Vapor Pressure of Biodiesel Fuels

The composition, vapour pressure, and heat capacity of nine biodiesel fuels from different sources were measured. The vapour pressure of the biodiesel fuels is modeled assuming an ideal liquid phase of the fatty acid methyl esters constituting the fuel. New methodologies to calculate the vapour pressure and ideal gas and liquid heat capacities of the biodiesel fuel constituents are proposed. Tw...

Life-Cycle Costs of Alternative Fuels: Is Biodiesel Cost Competitive for Urban Buses?

The purpose of this paper is to provide an expected cost comparison for operating a transit-bus fleet on three different alternative fuels-biodiesel, compressed natural gas (CNG), and methanol. Petroleum diesel is the base fuel. Infrastructure, refueling, and maintenance costs are all part of running an urban transit bus. Additional expenditures would be needed to change fuel storage and delive...

Alternative Fuels In Aviation

During the last years, the aviation sector has been looking into alternatives to kerosene from crude oil, to combat climate change by reduction of greenhouse gas (GHG) emissions and to ensure security of supply at affordable prices. The efforts are also a reaction to commitments and policy packages. Currently, a wide range of possible fuel candidates and fuel blends are discussed in the triple ...
