On-Site Ethanol in Gasoline Blend Analysis Saves Money and Eliminates Uncertainty in Fuel Blends
The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the Wilks InfraCal ...

Reducing noise from gasoline engine injectors
Test and analysis methods for gasoline fuel injector noise are presented along with representative results. Particular attention is paid to validating the test methods. Comparisons are made between a simple analytical model and measured results. Finally, correlation between perceived sound quality and existing acceptance criteria is summarised.Keywords: fuel injectors, acoustics, noise, ...

A review on exergetic analysis and assessment of various types of engines
This study presents a review on energy and exergy analysis of Otto and Diesel engines. Calculation methods of the analysis are discussed in detail. Previous studies, from 1963 to 2008, are chronologically listed and studied. The test engines had different cylinder numbers, speeds and rated powers. Engine specifications and test bench schematics are given in tables and figures. The best exergetic ...

Shannon entropy for energy technologies ex-ante evaluation
Most of the international literature has used Shannon entropy to measure the information gap. In this paper we propose a method that uses Shannon entropy to evaluate ex-ante energy technologies in a decision making process. It was called ITEM, i.e., Information Theory Energy technology ex-ante evaluation Method. The aim was to have a suitable tool for characterising the most critical project ...

An assessment of the aggregate impacts of the proposed reduction in the motor fuels tax in the United States
The analysis in this paper examines the impact of reducing the excise tax on gasoline and diesel fuel on the United States economy. The analytical approach used consists of a computable general equilibrium model composed of fourteen producing sectors, fourteen consuming sectors, six household categories classified by income and the government. The effects of a 4.3 cents per gallon reduction in ...

Getting the Market to Tell the Truth
Moving the global economy off its current decline-and-collapse path depends on reaching four goals: stabilizing climate, stabilizing population, eradicating poverty, and restoring the economy’s natural support systems. These goals--comprising what the Earth Policy Institute calls “Plan B” to save civilization--are mutually dependent. All are essential to feeding the ...

Ethanol Detection Enzyme - Case Study
BACKGROUND This project was prompted by feedback from the Michigan Department of Agriculture & Rural Development (MDARD). Ethanol has been added as an octane enhancer in some Michigan gasoline for some time, it increases the octane almost 3 Anti Knock Index points. If gasoline contains ethanol, there is a limit of 10% of total volume for conventional fuels. [1] Around 13 billion gallons of ...
