This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work investigated waste plastic pyrolysis oil (WPPO), 2-ethyl hexyl nitrate (EHN), and ethanol as sources of renewable energy, blending conventional diesel (CD), WPPO, and ethanol with EHN was to improve the combustion and performance characteristics of the WPPO blends. EHN has the potential to reduce emissions of CO, CO2, UHC, NOX, and PM. Ethanol improves viscosity, miscibility, and the oxygen content of WPPO. Mixing ratios were 50/WPPO25/E25, 60/WPPO20/E20, 70/WPPO15/E15, 80/WPPO10/E10, and 90/WPPO5/E5 for CD, waste plastic pyrolysis oil, and ethanol, respectively. The mixing ratio of EHN (0.01%) was based on the total quantity of blended fuel. Performance and emission characteristics of a stationary 4-cylinder water-cooled diesel Iveco power generator were evaluated with ASTM standards. At 1000 rpm, the BSFC was 0.043 kg/kWh compared to CD at 0.04 kg/kWh. Blend 90/WPPO5/E5 had the highest value of 14% for BTE, while the NOX emissions for 90/WPPO5/E5, 80/WPPO10/E10, and 70/WPPO15/E15 were 384, 395, and 414 ppm, respectively, compared to CD fuel at 424 ppm. This is due to their densities of 792 kg/m3, 825 kg/m3 which are close to CD fuel at 845 kg/m3 and the additive EHN. These results show blends of WPPO, ethanol and EHN reduce emissions, and improve engine performance, mimicking CD fuel.

Book Synopsis Performance of Biodiesel Blends on Compression Ignition Engine by : Rafidah Rahim
Download or read book Performance of Biodiesel Blends on Compression Ignition Engine written by Rafidah Rahim and published by . This book was released on 2012 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The developments in alternative energy sources have become gradually more applicable with the increasing exploration for an adequate alternative to oil-based energy. The depletion of the amount of fossil fuels worldwide is steadily creating an incentive to replace them, either partially or completely, with bio-fuels. The purpose of this study is to define and provide a comparison for biofuels, mineral diesel (D2) and straight vegetable oil (SVO). The main properties of fuels have been investigated experimentally in the Chemical Laboratory of the University of Malaysia in Pahang. There are seven fuels, including 5% Biodiesel blended with 95% mineral diesel (B5), 15% Biodiesel blended with 85% mineral diesel (B15), 20% Biodiesel blended with 80% mineral diesel (B20), 50% Biodiesel blended with 50% mineral diesel (B50), 100% Biodiesel (B100), Straight Vegetable Oil (SVO), and Diesel fuel (D2). Tests were conducted to determine the effect of biodiesel blended with diesel fuel on the following properties: the energy content, density, cetane number, viscosity, cloud and pour point, flash point, acid value and moisture content. From the properties testing, the small proportions of biodiesel blended, which included B5, B15, B20 and D2, were analysed for their performance in GT-Power engine simulation. Subsequently, some of properties that have been determined earlier will be used as an input in a GT-Power simulation model. The GT-Power model was built for a single cylinder diesel engine. The input model's engine specifications follow the diesel engine Yanmar TF-120M. Then the engine performance will be compared and discussed between the various blends of fuel. From the graph tendency, B5 is considerably pre-eminent for the good performance of the diesel engine. The higher energy content shows good agreement with the best performance of engine. This is because the lower energy content needs more BSFC to inject more fuel to gain equal brake torque and the same level of power. Nonetheless, the consequence of the lowest value of BSFC is obviously desirable. Attention was also alerted to the properties which influence the injection and engine characteristics extensively, thus affecting the quality of engine performance which also affects injector lubrication and fuel atomisation. Generally, biodiesel fuel blends can improve lubricant; nevertheless, the higher viscosity levels have a tendency to form larger droplets on injection that can cause exhaust smoke and poor combustion reactions.

Book Synopsis The Effects of Oxidized Biodiesel Fuel on Fatty Acid Methyl Ester Composition and Particulate Matter Emissions From a Light-Duty Diesel Engine by : Jack Elliot Reed
Download or read book The Effects of Oxidized Biodiesel Fuel on Fatty Acid Methyl Ester Composition and Particulate Matter Emissions From a Light-Duty Diesel Engine written by Jack Elliot Reed and published by . This book was released on 2021 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel particulate matter (PM) is classified by the EPA as carcinogenic, with the transportation sector largely responsible these emissions within the United States. Biodiesel (B100) is derived from renewable sources, providing similar chemical composition to diesel fuel and is in the current diesel supply up to 5% across the nation. However, biodiesel has an inherent oxidation issue due to the unique mixture of fatty acid methyl ester (FAME) molecules present in the biodiesel that are not in diesel. Biodiesel oxidation can only be delayed, and the inevitable process results in changes to the original fuel composition that may alter emissions profiles. There have been limited studies on the effect of oxidized biodiesel fuel on PM emissions, and with increasing biodiesel production volumes, it is important to assess due to possible adverse human health effects. In this study, it was hypothesized that the change in fuel composition due to oxidation would lead to lower PM emissions because the presence of more fuel oxygen molecules and secondary oxidation products would enhance self-combustion characteristics. In this study, PM mass generated from a light-duty diesel engine running on three different fuel types--pure ("neat") B100 biodiesel, pure B0 diesel, and B20 (20% v/v biodiesel blend with diesel)--was quantified and compared to the PM mass (and concentrations) from repeated emissions testing using artificially oxidized B100 and B20 biodiesel as the fuel source. B100 fuel was heated at 110oC for 5, 10, and 20 hours ("oxidation states" 3, 2, and 1, respectively), verifying the extent of fuel oxidation by building an apparatus (Biodiesel Oxidation Stability Surveyor, BOSS) that quantified the biodiesel fuel's oxidative stability using a method equivalent to standard methods for determining the biofuel's induction period. Induction period increased linearly with time spent under the artificial oxidation conditions. A custom, load-based steady-state modal drive cycle was specially developed for emissions testing each neat and oxidized B100 and B20 fuel type in a light-duty diesel engine dynamometer. Observed changes in PM mass with increased fuel oxidation time occurred only for B20 fuel with a 51 ±13% decrease. Fuel properties such as cetane number, biodiesel content, density, and total aromatics were compared between neat and oxidized B20 and B100 samples. Cetane number increased 7% from 66.8 to 71.7 from B100 neat to B100 OX1 (20hrs) and density increased from 0.709g/cm3 to 0.723g/cm3. Chemical analysis of the biodiesel fuels by gas chromatography mass spectrometry (GCMS) quantified individual FAME compounds to determine key species involved in fuel oxidation. B100 FAME concentration widely varied, however, the B20 fuel blend showed that 20 hour artificial oxidation treatment decreased concentrations of the unsaturated FAMEs for C18:3n3, C18:2 cis-9,12, C18:1 (both cis- and trans- isomers) by 41.7 ±3.5%, 33.25 ±8.8%, and 21.9 ±6.9% relative to their initial concentration in the unoxidized fuel, respectively, in general agreement with literature values. The findings of this study help contribute a better understanding of oxidation effects on biodiesel fuel and link together fuel properties, chemical composition, and particulate emissions whereas most literature excludes detailed analysis of biodiesel fuel composition and associated emissions effects.

Download or read book Optimization of Biodiesel and Biofuel Process written by Diego Luna and published by MDPI. This book was released on 2021-09-02 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the compression ignition (C.I.) engine, invented by Rudolf Diesel, was originally intended to work with pure vegetable oils as fuel, more than a century ago, it was adapted to be used with a fuel of fossil origin, obtained from oil. Therefore, there would be no technical difficulties in returning to the primitive design of using biofuels of renewable origin, such as vegetable oils. The main drawback is found in the one billion C.I. engines which are currently in use, which would have to undergo a modification in the injection system in order to adapt them to the higher viscosity of vegetable oils in comparison to that of fossil fuels. Thus, the gradual incorporation of biofuels as substitutes of fossil fuels is mandatory.
Book Synopsis Engine Performance and Exhaust Emissions of a Diesel Engine from Various Biodiesel Feedstock by : Bjorn Sanchez Santos

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing fuel prices, stricter government policies, and technological developments made it possible to seek for renewable alternatives, called biofuels, to petroleum fuel. Biodiesel, a biofuel that is produced from chemically mixing animal fat, vegetable oils, or recycled restaurant grease with alcohol and catalyst, is gaining popularity in recent years as a substitute for petroleum diesel. Ninety percent (90%) of U.S. biodiesel industry makes use of soybean oil as its feedstock. However, soybean oil alone cannot meet such a huge demand on biofuel production. Hence, it is important to identify and get more information about other feedstocks, specifically on its effects on the performance and exhaust emissions of diesel engines. The purpose of this study is to investigate the performance and emissions of two diesel engines operating on different biodiesel fuels (i.e. canola oil, sunflower oil, safflower oil, peanut oil, and chicken fat) and compare them to the performance and emissions when the engine is operated on soybean oil-based biodiesel and petroleum-based diesel. Results indicated that an engine operating on biodiesel generates a little less power and torque at any given speed than one running on diesel. Such power and torque loss were attributed to the biodiesel's lower energy content. The lower heating value (energy content) of biodiesel can be reflected in the specific fuel consumption, i.e., to generate the same power, more biodiesel is needed. The reduction in torque and power of less than 10% indicates that in some cases biodiesel has better combustion than diesel. Unfortunately, the high efficiency of combustion may give rise to increased combustion temperature which may lead to higher exhaust emissions. The gradual decrease in the total hydrocarbon and CO2 emissions, as blends were increased from B20 to B100, was also found to be an indication of better combustion using biodiesel fuels than petroleum diesel. However, NOx emissions were higher, predominantly at low speeds for most biodiesel and blends and therefore may require some additives or engine modifications/or adjustments to equalize the NOx emissions of diesel. Other emissions particularly SO2 were lower than standards require.
