This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the effects of oxygenated alcohol/gasoline/diesel fuel blends on performance, combustion, and emission characteristics in conventional reciprocating engines is reported. On the one hand, in alcohol-gasoline blends, dual alcohols-gasoline blends have not yet been sufficiently proven as suitable alternatives to single alcohol-gasoline blends in engines as far as performance is concerned. On the other hand, n-butanol-diesel, although it has a better miscibility factor in diesel than methanol or ethanol, is limited with regard to extensive application in the diesel engines due to its low cetane number. Engine performance was compared using single alcohol-gasoline and dual alcohol-gasoline blends, where the dual blends were constrained to meet the vapor issues regarding fuels and regulations. The blends were selected in terms of a combination by volume of one being higher alcohol (n-butanol) and the other, lower alcohol (methanol). The engines used for this study included a single-cylinder and a four-cylinder, naturally aspirated, four-stroke spark ignition engines and a four-cylinder, four-stroke compression ignition turbocharged diesel engine. In the n-butanol-diesel studies, a comparison was made with other studies in order to determine how suitable n-butanol-diesel blends were across the biofuel family such as the biodiesel-ethanol-diesel blends. The findings were as follows: The dual alcohols-gasoline blends performed better than the single alcohol-gasoline blends depending on certain compositional ratios of the alcohols in gasoline regardless of vapor pressure consideration. The n-butanol/diesel alcohol blend (B5, B10, and B20, where B5 represents 5% n-butanol and 95% diesel) significantly reduced the regulated emissions in a turbocharged engine compared to other studies using biodiesel-diesel blends. The significant decrease in NOx, CO emissions, and reduction of unburned hydrocarbons content using n-butanol/diesel fuel (DF) blends were found experimentally. The use of dual alcohol /gasoline blends was beneficial due to their shorter combustion duration in crank angles and their higher-energy content compared with single alcohol-gasoline blends. The n-butanol/diesel blend fired in the diesel engine showed a higher brake thermal efficiency and improved brake specific fuel consumption compared to the study by others where ethanol\diesel and methanol\diesel blends were used.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The 2007 U.S. Renewable Fuel Standard (RFS2) requires an increase in the use of advanced biofuels up to 36 billion gallons by 2022. Higher carbon number alcohols, in addition to cellulosic ethanol and synthetic biofuels, could be used to meet this demand while adhering to the RFS2 corn-based ethanol limitation. Alcohols of carbon numbers 2 through 8 are chosen based on their chemical and engine-related properties. Blend comparison metrics are developed from automotive industry trends, consumer expectations, U.S. fuel legislation, and engine requirements. The metrics are then used to create scenarios by which to compare higher alcohol fuel blends to traditional ethanol blends. Each scenario details an overall objective and identifies chemical and engine-related properties that are crucial to meeting that objective as fuel criteria. Fuel blend property prediction methods are adopted from literature and used to calculate both linear and non-linear properties of multi-component blends. Possible combinations of eight alcohols mixed with a gasoline blendstock are calculated and the properties of the theoretical fuel blends are predicted. Blends that meet all of a scenario's criteria are identified as suitable blends. Blends of higher carbon number alcohols with gasoline blendstock are identified as optimal blends for each scenario if they meet all of the scenario's criteria and maximize either energy content, knock resistance, or petroleum displacement. Optimal blends are tested in a spark-ignition engine. The effect of higher carbon number alcohols as a fuel component on engine performance and emissions is examined. Results suggest that combustion properties of blends of alcohols with carbon numbers from two to six are similar to those of the reference fuel at low and medium engine loads. Properties of blends of alcohols with carbon numbers from two to four are similar to those of the reference fuel even at high loads. However, due to their reduced knock resistance, the suitability of longer chain alcohols, specifically C5 and longer, as blending agents at increased levels is questionable.

Book excerpt: Renewable energy sources such as biodiesel, bioethanol, biomethane, biomass from wastes or hydrogen are subject of great interest in the current energy scene. These fuels contribute to the reduction of prices and dependence on fossil fuels. In addition, energy sources such as these could partially replace the use of what is considered as the major factor responsible for global warming and the main source of local environmental pollution. For these reasons they are known as alternative fuels. There is an urgent need to find and optimise the use of alternative fuels to provide a net energy gain, to be economically competitive and to be producible in large quantities without compromising food resources.

Available in PDF, EPUB and Kindle. Book excerpt: Energy and the environment are inextricably linked to the economy. Thermodynamics therefore seems to be a privileged tool in overcoming the constraints associated with optimization.This first volume reports on an original, contemporary approach leading to optimal solutions in the form of trend models, proving the existence of solutions which can then be refined in a more complete and sophisticated manner.The validation of the proposed methodology is realized through real-life examples (engines, heat pumps, refrigeration systems, etc.). However, the more fundamental aspects linked to the dynamics of the transfer and conversion of energy and matter are also explored, as well as the evolution which characterizes the second law of thermodynamics.This book presents recent advances, often still undergoing research, as well as structured exercises, and is therefore aimed at both students and researchers in the field of energetics. It proposes a view of the evolution of knowledge regarding the thermodynamics modeling of systems and processes It shows results and also the existence of optimum all and along the development It focuses on multidisciplinary approach that characterizes thermodynamics

This book was released on 2020 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Usage of oxygenates has become common practice for improving gasoline properties. In this study, two oxygenates, one from the ether family (diisopropyl ether (DIPE)) and one from the alcohol family (n-butanol), were mixed with gasoline at 5, 15, and 25 % by volume to get D5, D15, D25, N5, N15, and N25 blends. Blends of DIPE (D5, D15, and D25) and n-butanol (N5, N15, and N25) were tested in a four-stroke four-cylinder multipoint fuel injection spark-ignition engine at 0.33 MPa (brake mean effective pressure) over a speed range of 1,400 to 2,800 r/min with 200 r/min increments. The performance and emission behavior obtained from blends of DIPE and n-butanol were compared with base gasoline. Lower hydrocarbon and carbon monoxide emissions are observed for oxygenate blends than for gasoline. However, blends of DIPE and butanol emitted higher nitrogen oxide (NO x ) than gasoline. The retarded spark timing from 14° before top-dead-center (bTDC) to 12° bTDC reduced NO x emissions from blends. The study also concludes that DIPE is a suitable and comparable oxygenate additive to n-butanol and offers high knock resistance equal to n-butanol.
