Alcohol enhanced alternative fuels

Abstract: Oxygenated hydrocarbon fuel compositions for use in internal combustion engines with naphtha, alcohol(s), and ether(s) with or without additives are disclosed. Combustion of the fuel compositions results in reduced pollution emissions compared to conventional gasoline and can cost must less than conventional gasoline with comparable or improved engine performance.

Influence of Vegetable Oil Based Alternate Fuels on Residue Deposits and Components Wear in a Diesel Engine

Abstract: A 25-75 blend (v/v) of alkali-refined sunflower oil and diesel fuel, a 25-75 blend (v/v) of high oleic safflower oil and diesel fuel, a non-ionic sunflower oil-aqueous ethanol microemulsion, and a methyl ester of sunflower oil were evaluated as fuels in a direct injected, turbocharged, intercooled, 4-cylinder Allis-Chalmers diesel engine during a 200-hour EMA cycle laboratory screening endurance test. Engine performance on Phillips 2-D reference fuel served as baseline for the experimental fuels. This investigation employed an analysis of variance to compare CRC carbon and lacquer ratings and wear of engine parts for all tested fuels. The paper deals with carbon and lacquer formation and its effect on long-term engine performance as experienced during the operation with the alternate fuels. Significantly heavier deposits than for the diesel fuel were observed for the microemulsion and 25-75 sunflower oil blend. particularly on the exhaust and intake valve stems, on the piston lands, and in the piston grooves. In all tests engine wear was not significant. The final dimensions of the measured elements did not exceed the manufacturer's initial parts specifications.

Effect of Anode Material on Electrochemical Oxidation of Low Molecular Weight Alcohols-A Review.

Abstract: The growing climate crisis inspires one of the greatest challenges of the 21st century—developing novel power sources. One of the concepts that offer clean, non-fossil electricity production is fuel cells, especially when the role of fuel is played by simple organic molecules, such as low molecular weight alcohols. The greatest drawback of this technology is the lack of electrocatalytic materials that would enhance reaction kinetics and good stability under process conditions. Currently, electrodes for direct alcohol fuel cells (DAFCs) are mainly based on platinum, which not only provides a poor reaction rate but also readily deactivates because of poisoning by reaction products. Because of these disadvantages, many researchers have focused on developing novel electrode materials with electrocatalytic properties towards the oxidation of simple alcohols, such as methanol, ethanol, ethylene glycol or propanol. This paper presents the development of electrode materials and addresses future challenges that still need to be overcome before direct alcohol fuel cells can be commercialized.
