Book excerpt: The use of biodiesel is one of the alternatives to reduce oil dependence in the transport sector and to reduce greenhouse gas emissions. One of the most common engines in Europe was subjected to some tests, aiming to discover the efficiency effects and the emission characteristics when consuming a fuel containing 20% of biodiesel and 80% of diesel (B20), and comparing the results with the use of 100% diesel (B0). Using an engine test bench, several working points of the engine were chosen considering different engine rotation from idle speed to 3500 rpm and from residual torque to 120 Nm, covering the great majority of the normal running operation of this kind of engines when installed in light vehicles. The results revealed a non-proportional effect for fuel consumption for different engine regimes where the energetic differences were, in some operation regimes, totally compensated with efficiency increase. The NOx emission analysis allows to admit that the use of biodiesel in the fuel leads to a consequence on emissions increase that is not always obvious, since in some regimes that increase is noticeable, but for other regimes a slight decrease or no significant change was detected.

Book excerpt: This book provides a detailed overview of aspects related to the overall provision chain for biokerosene as part of the global civil aviation business. Starting with a review of the current market situation for aviation fuels and airplanes and their demands, it then presents in-depth descriptions of classical and especially new types of non-edible biomass feedstock suitable for biokerosene provision. Subsequent chapters discuss those fuel provision processes that are already available and those still under development based on various biomass feedstock materials, and present e.g. an overview of the current state of the art in the production of a liquid biomass-based fuel fulfilling the specifications for kerosene. Further, given the growing interest of the aviation industry and airlines in biofuels for aviation, the experiences of an air-carrier are presented. In closing, the book provides a market outlook for biokerosene. Addressing a broad range of aspects related to the pros and cons of biokerosene as a renewable fuel for aviation, the book offers a unique resource.

Book Synopsis Lowering USAF Diesel Engine NOx Emissions With Utilizing B20 Biodiesel Fuel by :
Download or read book Lowering USAF Diesel Engine NOx Emissions With Utilizing B20 Biodiesel Fuel written by and published by . This book was released on 2005 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Air Force can utilize B20 biodiesel fuel to partially meet EPAct requirements for alternative fuel use, and to lower criteria pollutants except for NOx. Relatively minor production component changes, and selected minor operating condition changes can alter engine out NOx emissions with biodiesel fuels in a 6.5L HMMWV engine. For a nonroad ISO 8178 test cycle, weighted average Smoke/PM emissions can be similar to DF-2 levels at the condition that gives equivalent NOx emissions with B20 biodiesel fuel. In other words, Smoke/PM emissions with B20 biodiesel can be traded-off for improved NOx emissions. For the 6.5L HMMWV engine tested the composite control strategy did not severely impact emissions or fuel consumption when the engine operated on JP-8 fuel.
Book Synopsis Performance and Emissions of a DI Diesel Engine Fueled by Different Biodiesel Blends by : Majed M. Alawi
Download or read book Performance and Emissions of a DI Diesel Engine Fueled by Different Biodiesel Blends written by Majed M. Alawi and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiesel has been a promising clean alternative fuel to fossil fuels, which reduces the emissions that are released by fossil fuels, and possibly reduces the energy crisis caused by the exhaustion of petroleum resources in the near future. Biodiesel is replacing diesel as an alternative fuel for internal combustion engines. Previous research studies have shown that biodiesel can greatly reduce carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM) emissions compared to diesel fuels, but very few studies have shown a reduction in total nitrogen oxides (NOx). At present, B20 (20% biodiesel in the total fuel mix) is being used commonly in the US due to its material compatibility to changing weather conditions, emission benefits and costs. Currently, Canada is planning to use 5% of biodiesel by 2015. The objective of this study is to test the feasibility of biodiesel in cold climates such as Canada. The biodiesel used is made of canola oil obtained from a local supermarket and winter diesel is used as a reference fuel. Three different series were used. The first series was biodiesel/diesel with six blends (B0, B5, B10, B20, B50 and B100). The second series was biodiesel/diesel plus 2% of a chemical additive (B0, B5A, B10A, B20A, B50A and B100A). The final was kerosene/biodiesel series (K0, K5, K10, K20, K50 and K100). Chemical additive (Wintron XC30) is used to lower the cloud point of the blends and this is the first attempt to investigate its effect on engine emissions. On the other hand, there are limited studies on kerosene being treated as a blending fuel, where it is mainly used to lower the cloud point of the blends to investigate the feasibility of biodiesel in a cold climate such as the winter season in Canada and suggest an appropriate solution for the future of biofuel. Engine performance and emission concentrations are investigated by determining the break specific fuel consumption (bsfc), fuel conversion efficiency and measuring emission concentrations of CO, HC, NO, NO2 and NOx using gas analysers. Engine tests are performed on a constant rated speed at three different load conditions. A comparison is made for the three series. Most of the blends have shown improved emissions compared to fossil diesel. B5A demonstrated a lower cloud point than fossil diesel, and the kerosene series showed excellent results at high load conditions.

Book Synopsis Combustion and Emissions of a Diesel Engine Fueled with Diesel-Biodiesel-Ethanol Blends and Supplemented with Intake CO2 Charge Dilution by : Ho Tse

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the influence of a four-cylinder naturally aspirated direct-injection diesel engine fueled with diesel-biodiesel-ethanol blended (DBE) fuels tested at a steady state speed of 1800 rev/min under different engine loads, ethanol volume and intake carbon dioxide (CO2) dilution ratios on engine performance, combustion characteristics, regulated gaseous emissions, and soot agglomerates. Overall, the experimental results indicate that DBE blends can in general improve brake thermal efficiency (BTE) and reduce nitrogen oxides (NOx), carbon monoxide (CO), CO2, volatile organic fractions, particulate mass (PM), and particulate number (PN) concentrations, while brake-specific fuel consumption (BSFC) and hydrocarbon (HC) might increase slightly. Compared with ultra-low-sulfur diesel, DBE blends can maintain a good tradeoff relationship among PM-PN-NOx. Compared with biodiesel, the blended fuels perform better in suppressing brake-specific particle number emissions (BSPN), leading to a reduction of ultrafine and nanoparticle numbers. The combined effect of DBE blends with intake CO2 dilution has marginal effects on BSFC and BTE, significantly reducing NOx emission while slightly increasing particulate emissions. On particulate characteristics, DBE blends produce soots with curved, tortuous, and disorganized nanostructures with low soot burnout temperature and strong oxidation rate favoring PM-PN reduction.

Book Synopsis Biodiesel Fuels Based on Edible and Nonedible Feedstocks, Wastes, and Algae by : Ozcan Konur
Download or read book Biodiesel Fuels Based on Edible and Nonedible Feedstocks, Wastes, and Algae written by Ozcan Konur and published by CRC Press. This book was released on 2021-05-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume of the Handbook of Biodiesel and Petrodiesel Fuels presents a representative sample of the population papers in the field of feedstock-specific biodiesel fuels. The research on feedstocks for biodiesel fuels has first focused on the edible oils as first-generation biodiesel fuels. However, the public concerns about the competition with foods based on these feedstocks and adverse impact on the ecological diversity and deforestation have resulted in the exploration of nonedible-oil-based biodiesel fuels as second-generation biodiesel fuels in the first instance. Due to the ecological and cost benefits of treating wastes, waste oil-based biodiesel fuels as third-generation biodiesel fuels have emerged. Furthermore, following a series of influential review papers, the research has focused on the algal oil-based biodiesel fuels in recent years. Since the cost of feedstocks in general constitutes 85% of the total biodiesel production costs, the research focused more on improving biomass and lipid productivity in these research fields. Furthermore, since water, CO2, and nutrients (primarily N and P) have been major ingredients for the algal biomass and lipid production, the research has also intensified in the use of wastewaters and flue gases for algal biomass production to reduce the ecological burdens and the production costs. Part 1 presents a representative sample of the population papers in the field of edible oil-based biodiesel fuels covering major research fronts. It covers soybean oil-based biodiesel fuels, palm oil-based biodiesel fuels, and rapeseed oil-based biodiesel fuels as case studies besides an overview paper. Part 2 presents a representative sample of the population papers in the field of nonedible oil-based biodiesel fuels covering major research fronts. It covers Jatropha oil-based biodiesel fuels, polanga oil-based biodiesel fuels, and moringa oil-based biodiesel fuels as case studies besides an overview paper. Part 3 presents a representative sample of the population papers in the field of waste oil-based biodiesel fuels covering major research fronts. It covers wastewater sludge-based biodiesel fuels, waste cooking oil-based biodiesel fuels, and microbial oil-based biodiesel fuels as case studies besides an overview paper. Part 4 presents a representative sample of the population papers in the field of algal oil-based biodiesel fuels covering major research fronts. It covers algal biomass production in general, algal biomass production in wastewaters, algal lipid production, hydrothermal liquefaction of algal biomass, algal lipid extraction, and algal biodiesel production besides an overview paper. This book will be useful to academics and professionals in the fields of Energy Fuels, Chemical Engineering, Physical Chemistry, Biotechnology and Applied Microbiology, Environmental Sciences, and Thermodynamics. Ozcan Konur is both a materials scientist and social scientist by training. He has published around 200 journal papers, book chapters, and conference papers. He has focused on the bioenergy and biofuels in recent years. In 2018, he edited ‘Bioenergy and Biofuels’, that brought together the work of over 30 experts in their respective field. He also edited ‘Handbook of Algal Science, Technology, and Medicine’ with a strong section on the algal biofuels in 2020.

Book Synopsis Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles by : National Research Council
Download or read book Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2015-09-28 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.
