Abstract:
Global total petroleum deficit and environmental concern on the emissions issues concerning pure diesel had started a technological race in producing alternative sources of energy which includes renewable fuel. Among the developed renewable fuels is the biodiesel which is a type of fuel derived from various sources of vegetable plants and waste fuels. Various biodiesels have been engineered to beat par to or even perhaps, a leap better in term of performance topure diesel. In short,biodiesel has shown a promising sign as the best candidate in overcoming total dependent on petroleum-derived fuel.This paper gives review on various tests and experiments conducted on biodiesel in order to highlight the potentials preserved by the fuel and to further endorse for a more mass usage of biodiesel and simultaneously for Malaysia to be a potential global producer of biodiesel fuels in the near future.

Abstract:
The present experimental investigation is carried out to establish the stability, compatibility and feasibility of working characteristics of DICI engine by using Jatropha biodiesel, Pongamia biodiesel and related water emulsion biodiesels. Experiments are carried out in two phases on a DICI engine test rig which includes CI engine, electric loading device, exhaust gas analysers, and a data-acquisition system. The performance and emission characteristics of the engine are studied by using neat diesel, Jatropha and Pongamia biodiesel in the first phase, and similar experiments are conducted by water – biodiesel emulsion fuels in the second phase. The water–biodiesel emulsion fuels are prepared with the aid of a mechanical homogenizer in the proportion of 10% water, 88 % biodiesel, and 2 % surfactants (by volume). Sequentially, the stability characteristics of water–biodiesel emulsion fuels are analyzed. The results indicated that slight improvement in BTE and BSFC for water – biodiesel emulsion fuels compared to biodiesel fuels. The exhaust emissions of NOx and smoke opacity were decreased for the water biodiesel emulsion fuels as compared to respective neat biodiesel and neat diesel. CO & unburned HC emissions were slightly increased for the water biodiesel emulsion fuels compared to respective neat biodiesels and less than of neat diesel.

Abstract:
Biodiesel, a sustainable alternative to traditional petroleum-based diesel, can be derived from various sources such as vegetable oils, animal fats, and recycled cooking oils. Its production and use have gained momentum due to its potential to reduce greenhouse gas emissions and diminish our reliance on fossil fuels. The combustion of fossil fuels contributes significantly to climate change and various forms of pollution. In India's agricultural sector, the production of biodiesel from non-edible plant oils has witnessed a surge in popularity. However, the current supply of these biodiesels falls short of meeting the growing demand for fossil fuels. To address this challenge, a novel biodiesel formulation using non-edible oils has been developed. This study aims to create an innovative biodiesel blend comprising 50% cottonseed biodiesel, 50% rapeseed biodiesel, and diesel with the addition of cerium oxide. The results obtained with CR20N50 indicate a substantial 15–18% reduction in fuel consumption, a notable 12–22% decrease in carbon monoxide emissions, and a significant 13–20% reduction in hydrocarbon emissions compared to conventional diesel fuel.

Abstract:
Most energy is produced from fossil fuels, and the use of these fuels has increased over the past years. Fossil fuels are the main cause of global pollution and global warming. Using vegetable oils as alternative fuels for diesel engines is one of the ways to reduce pollutant emissions. Biodiesel from Norozak (Salvia lerrifolia) oil has been produced using a transesterification process. Biodiesel is mixed with diesel oil in different proportions B05, B10, B15, and B20. Biodiesel's physical and chemical properties are measured according to ASTM standards. A single-cylinder diesel engine is employed as the test engine in the present work. The torque, power, Special Fuel Consumption (SFC), and Exhaust Gas Temperature (EGT) are measured and compared with diesel oil. Torque, power, and EGT are larger, and SFC is lower for biodiesel mixture B05 than diesel fuel.

Abstract:
An experimental study was conducted to investigate the effect of high-ratio biodiesel and pure biodiesel on the emissions and performance of Euro4-compliant vehicles. The tested fuels were diesel fuel, biodiesel with a ratio of 30% by volume (B30), biodiesel with a ratio of 50% (B50) and pure biodiesel FAME (B100), while the tested vehicle is of the Euro4-compliant standard currently available in the Indonesian market. In this study, tests on emissions, performance and fuel economy were conducted based on the international standard of the UN ECE R83-05, adopted as UN ECE R-85 and UN ECE R-101 respectively. This study also investigated the effect of the carbon-to-hydrogen ratio on the carbon balance formula. Here, the paper proposed a modified R101 carbon balance formula to calculate the fuel economy for high-ratio and pure biodiesel fuels. The results showed that biodiesel had lower CO, HC and particulate emissions, while NOx emissions were higher compared to diesel fuel. However, pure biodiesel was within the limits imposed by the Euro4 emissions standard. Maximum power output with high-ratio biodiesel decreased by up to 10% with B100. The fuel economy of the B30, B50 and B100 biodiesels was lower than diesel fuel by 3%, 7% and 11%, respectively, based on the modified carbon balance formula for high-ratio biodiesel fuel.

Abstract:
Progressive and increasingly noticeable climate change is forcing the search for new energy sources to reduce greenhouse gas emissions, especially carbon dioxide. One way to reduce greenhouse gas emissions is by gradually replacing fossil fuels with biofuels. The authors of this work addressed the production of second-generation biofuel. The purpose of this study was to produce second-generation biodiesel from babassu palm oil (BBuE) and first-generation biodiesel from rapeseed oil (RME), to study their properties, and to determine the effect of the addition of these biodiesels to diesel fuel on selected properties of “B” fuels that affect the fuel–air mixture formation process and the combustion process. Biodiesel from babassu oil was produced because it is non-edible and has a different composition than canola oil. Then, fuels were prepared that were mixtures of diesel oil and biodiesel containing from 10 to 40% (v/v) BBuE or RME (B10, B20, B30, and B40).Tests were conducted on selected physicochemical properties of the obtained fuels. “B” fuels prepared with BBuE and DF were shown to have more favorable fuel properties than those obtained from RME and DF. Fuels that are blends of BBuE and DF have slightly higher heating values, higher cetane number values, a more favorable distillation curve, lower dynamic viscosity values as a function of temperature, and marginally lower flash point values compared to the corresponding blends of RME and DF. Esters with shorter molecules have been shown to have more favorable fuel properties.

Abstract:
In this paper, the exergy analysis and environmental assessment are performed to the biodiesel and diesel-fueled engine at full 294 Nm and 1800 r/min. The exergy loss rates of fuels are found as 15.523 and 18.884 kW for the 100% biodiesel (BDF100) (obtained from cooking oil) and Japanese Industrial Standard Diesel No. 2 (JIS#2) fuels, respectively. In addition, the exergy destruction rate of the JIS#2 fuel is found as 80.670 kW, while the corresponding rate of the BDF100 is determined as 62.389 kW. According to environmental assessments of emissions and nanoparticles of the fuels, the biodiesel (BDF100) fuel is more environmentally benign than the diesel (JIS#2) fuel in terms of particle concentration and carbon monoxide and hydrocarbon emissions. So, it is better to use this kind of the 100% biodiesels in the diesel engines for better environment and efficiency in terms of the availability and environmental perspectives.

Abstract:
For economic and social development of any country energy is one of the most essential requirements. Continuously increasing price of crude petroleum fuels in the present days coupled with alarming emissions and stringent emission regulations has led to growing attention towards use of alternative fuels like vegetable oils, alcoholic and gaseous fuels for diesel engine applications. Use of such fuels can ease the burden on the economy by curtailing the fuel imports. Diesel engines are highly efficient and the main problems associated with them is their high smoke and NOx emissions. Hence there is an urgent need to promote the use of alternative fuels in place of high speed diesel (HSD) as substitute. India has a large agriculture base that can be used as a feed stock to obtain newer fuel which is renewable and sustainable. Accordingly Uppage oil methyl ester (UOME) biodiesel was selected as an alternative fuel. Use of biodiesels in diesel engines fitted with mechanical fuel injection systems has limitation on the injector opening pressure (300 bar). CRDI system can overcome this drawback by injecting fuel at very high pressures (1500-2500 bar) and is most suitable for biodiesel fuels which are high viscous. This paper presents the performance and emission characteristics of a CRDI diesel engine fuelled with UOME biodiesel at different injection timings and injection pressures. From the experimental evidence it was revealed that UOME biodiesel yielded overall better performance with reduced emissions at retarded injection timing of -10° BTDC in CRDI mode of engine operation.

Abstract:
Random extraction and consumption of fossil fuels have leads to a reduction in petroleum reserves. As for as developing countries like India is connected the need to search for alternative fuels is most urgent as India is heavily dependent upon the import of petroleum to meet its demands for automotive and power sectors. This has inspired curiously in alternative sources for petroleum based fuels. An alternative fuel must be economically competitive and environmentally acceptable. India has great potential for production of biofuels like Biodiesel from vegetable seeds. In the quest to find an alternative to the existing diesel and petrol fuels various Biodiesel and alcohol has been tried and tested in the Internal Compression engine. In this direction, an attempt has been made to investigate the performance and emission characteristic of Biodiesels and compare it with diesel. The Biodiesels considered are Tamanu, Mahua and Pongamia were tested with four stroke diesel engine. A drastic improvement in reduction of Hydrocarbon (HC) and Carbon monoxide (CO) were found for Biodiesels at high engine loads. Smoke and Nitrogen oxides (NOx) were slightly higher for Biodiesels. Biodiesels exposed similar combustion stages to diesel fuel. Therefore use of transesterified vegetable oils can be partially substituted for the diesel fuel at most operating conditions in term of the performance parameters and emissions without any engine modification.

Abstract:
Because of the depletion of the world’s petroleum reserves and the increasing environmental concerns, biodiesel, as a low-emission renewable fuel and one of the best substitutes for petro-diesel fuel, has attracted great public interest over the past decades. At present, camelina oil has been considered as a low-cost feedstock for biodiesel production because of its high oil content and environmental benefits. In the present study, the optimization of biodiesel production and purification from camelina oil is studied extensively in order to maximize the biodiesel yield. The orthogonal array design is used to optimize the biodiesel production and four relevant process conditions for affecting biodiesel yield are investigated: methanol to oil ratio, catalyst concentration, reaction time and temperature. For the optimization study on biodiesel purification, five commonly used washing methods are also investigated: cold deionized water washing, hot deionized water washing, phosphoric acid washing, ultrasonic assisted washing, and magnesol washing. The optimization study, based on traditional mechanical stirring process, reveals that the decreasing ranking of significant factors for biodiesel production is catalyst concentration > reaction time > reaction temperature > methanol to oil ratio. The maximum biodiesel yield is found at a molar ratio of methanol to oil of 8:1, a reaction time of 70 min, a reaction temperature of 50℃, and a catalyst concentration of 1 wt.%. After testing the fuel properties of the final product, the optimized biodiesel meets the relevant requirements of the biodiesel standards and thus can be used as a qualified fuel for diesel engines. The optimization study, based on ultrasonic-assisted transesterification process, reveals that the maximal fatty acid methyl ester yield of the final biodiesel product is obtained under a methanol to oil molar ratio of 8:1, catalyst concentration of 1.25 wt.%, reaction time of 50 min and reaction temperature of 55 ℃. Compared with traditional mechanical stirring production process, ultrasonic-assisted transesterification process improves the biodiesel production since it could reduce the production cost and save energy. For the optimization study on biodiesel purification, the fatty acid methyl ester yield of the final biodiesel product, energy consumption and economic costs of different washing methods are compared. The comparisons indicate that the ultrasonic assisted washing method is the best method for biodiesel purification, when energy consumption and operation costs are considered. A preliminary kinetics study of transesterification reaction of camelina oil is carried out. After discussing four cases for overall reaction, a third-order reaction mechanism was proposed to fit the experimental data better because of the highest coefficient of determination. Based on the best-fit plot, the rate constants and activation energy are also determined. To sum up, the present research focuses on the optimization of biodiesel production and purification from camelina oil, and provides insights into the optimal process conditions for maximizing the biodiesel yield. Further research works are finally recommended to be continued.

バイオディーゼルは、メタノールと触媒を使用したエステル交換プロセスによって製造されます。バイオディーゼルには、高セタン価、酸化安定性、低排出など、いくつかの利点があります。ただし、バイオディーゼルの高粘度と沸騰温度は、ディーゼルエンジンの噴霧燃焼に影響を与える可能性があります。したがって、高燃料と低沸点燃料を混合することでバイオディーゼルの特性を改善するために、新しい燃料設計法が適用されます。
Biodiesel is one of the promising alternative fuels in the future. Biodiesel is made from the trans-esterification process that uses methanol or alcohol and catalyst. The use of biodiesel in diesel engine has some advantages such as high cetane number, oxidation stability and can reduce some emissions. However, high viscosity, boiling temperatures and surface tension in biodiesel may affect the spray characteristics as compared to diesel oil. To overcome the unbenefited in biodiesel, therefore, the new fuel designed method that high-boiling point fuel is mixed to a low-boiling point fuel is applied in order to improve the properties in biodiesels.

Abstract:
A qualidade dos combustíveis é um dos principais fatores que afetam o desempenho dos motores de combustão interna e é caracterizada por um conjunto de propriedades físicas e químicas. Neste trabalho foi investigada a influência da temperatura sobre algumas propriedades como a densidade, viscosidade dinâmica, ponto de névoa e de fluidez de diferentes combustíveis. Além disso, medidas envolvendo termogravimetria e espectrometria na região do infravermelho médio também foram conduzidas. Medidas de densidade em função da temperatura ou da concentração de biodiesel na amostra revelaram uma dependência linear, de forma que a redução da temperatura ou o aumento da concentração de biodiesel provocaram um aumento da densidade. O estudo reológico a partir de medidas de viscosidade permitiu identificar o comportamento de fluido Newtoniano para todas as amostras analisadas. Um ajuste exponencial do tipo Arrhenius foi utilizado para analisar a correlação entre viscosidade dinâmica e temperatura, possibilitando identificar uma temperatura limite, T*, abaixo da qual esse ajuste não é mais satisfeito e o processo de solidificação da amostra é desencadeado. Um diagrama de fases em função das temperaturas T*, do ponto de névoa e de fluidez foi elaborado, possibilitando identificar, em função da concentração de biodiesel da amostra, faixas de temperaturas onde as fases líquidas e/ou sólidas podem ser encontradas, bem como onde o ajuste entre a viscosidade dinâmica e a temperatura pode ser obtido por uma equação exponencial do tipo Arrhenius. Além disso, medidas calorimétricas revelaram uma maior energia por unidade de massa para as amostras de diesel padrão, e que esta energia decresce linearmente com o incremento da concentração de biodiesel na amostra. Termogramas revelaram diferentes perfis de degradação térmica para as amostras, de forma que um deslocamento da curva de degradação para temperaturas mais elevadas foi observado em função do aumento do teor de enxofre nas amostras de diesel padrão assim como pelo incremento da concentração de biodiesel nas amostras produzidas pela mistura entre diesel e biodiesel. A análise das amostras líquidas utilizando radiação com comprimento de ondas no infravermelho permitiram identificar diferentes grupos funcionais presentes nas amostras e estabelecer, em termos da intensidade da absorbância característica da dupla ligação Carbono-Oxigênio presentes nos ésteres do biodiesel, uma relação com a concentração de biodiesel presente na amostra. Neste sentido, por meio da análise de diferentes propriedades físicas e químicas das amostras estudadas, foi possível avaliar características e interdependências destas propriedades, principalmente no que diz respeito a variações da temperatura. Sendo assim, ao longo deste trabalho, são apresentados dados e apontamentos importantes para tratar do tema abordado.
Fuel quality is a major factor affecting the performance of internal combustion engines and it is characterized by a combination of physical and chemical properties. In this study, the influence of temperature on some properties such as density, dynamic viscosity, cloud point and pour point were investigated in different samples of fuels. In addition, measurements involving thermogravimetry and infrared spectroscopy were also performed. Density measurements as a function of temperature or concentration of biodiesel in the sample revealed a linear dependence, indicating that the temperature reduction or increase of the concentration of biodiesel results in a density increase. The rheological study from dynamic viscosity measurements identified the Newtonian fluid behavior for all samples. It was also observed an increase in the dynamic viscosity caused by the increase of the concentration of biodiesel in the sample and also the reducing the temperature. An exponential fit of the Arrhenius type equation was used to analyze the correlation between dynamic viscosity and temperature, allowing to identify a temperature limit, T*, below which this adjustment is lost and the sample solidification process is triggered. A phase diagram as a function of the biodiesel concentration and the temperature T*, the cloud point and poor point was prepared. This diagram shows the temperature ranges in which liquid and/or solid phases can be found, and where the fit between the temperature and dynamic viscosity can be obtained by an exponential equation of Arrhenius type. In addition, calorimetric measurements revealed a higher energy per mass unit for the standard diesel samples, and that this energy decreases linearly with increasing of biodiesel content. Thermal analysis showed different degradation profiles for the samples. Thermograms indicated a shift of the degradation curve at higher temperatures due to the increase in the sulfur content in the samples of standard diesel and also increasing the biodiesel concentration in the samples produced by mixture of diesel and biodiesel. The analysis of liquid samples using infrared radiation allowed the identification of different functional groups present in the samples and to establish, in terms of the intensity of the absorbance characteristic of the carbon-oxygen double bond present in the esters of biodiesel, a relation with the concentration of biodiesel present in the sample. In this sense, through the analysis of different physical and chemical properties of the samples, it was possible to evaluate characteristics and interrelationships of these properties, particularly in respect of temperature variations, which can favor or disfavor the increased biodiesel concentration in blends with diesel. Thus, throughout this study are presented important data and notes related with the theme.

Abstract:
Numerous factors have pushed energy from biomass to the forefront of policy and industry discussions. Large harvests of traditional crops, low farm prices, dependence on foreign energy sources, and environmental problems have increased interest in renewable energy sources. Tools are needed to evaluate and compare different available feedstocks and to identify parameters and modifications for the production of renewable fuels such as biodiesel. The first paper examines the development of a biodiesel process model using commonly available spreadsheet software and process-engineering principles. The basis of the model is a continuous process with two stirred-tank reactors and sodium methoxide catalysis. The process is modeled as 27 units with 51 flows and 18 components. Mass flow rates and compositions of the process input and output streams are quantified using mass and component balances, energy balances, stoichiometric relations, and established process parameters. Oil composition and rate, methanol:triglyceride ratio, and expected transesterification of triglyceride are the user-specified inputs in the model. Based on commonly reported parameters (6: 1 methanol:triglyceride ratio and 98% transesterification) and a basis of 100 kg/h crude soybean oil, the model computes inputs of 13.8, 10.8, and 34.7 (in kg/h) for methanol, 10% sodium methoxide in methanol, and process water, respectively; and outputs of 93.5, 10.3, and 55.6 for soy biodiesel, glycerol, and waste stream, respectively. In the second paper, the mass flow rate data from the developed biodiesel process model are linked to cost data for evaluating the economic feasibility of biodiesel production in North Dakota with canola oil as the feedstock. Estimations of capital investment cost and total annual biodiesel product cost are conducted for two canola biodiesel production plants with 5 and 30 million gallons per year (MGY) capacities. These capacities were selected based on North Dakota and neighboring states' biodiesel demands, respectively. Capital investment cost analysis shows the presence of considerable economies of scale for the biodiesel production process for the two capacities. These cost calculations are based on the purchased equipment cost calculated from the equipment specifications. Total annual biodiesel product cost analysis shows that the major portion (>80%) of the total product cost is the raw material cost, similar to the analysis of previous economic feasibility studies. Cost benefits from the economies of scale are still present for the fixed charges, general expenses, and the manufacturing costs (other than the raw material costs) in the annual product cost calculations for the two production plant capacities. Finally, based on the gross profit evaluation for both plants, this study concludes that it is more worthwhile to invest in the 30 MGY production plant because of the greater cost returns from the economies of scale benefits. The results are more encouraging after the incorporation of the federal biodiesel tax incentive and favor the investment for biodiesel production in North Dakota.

Abstract:
This paper presents emissions modeling and testing of a four-stroke single cylinder diesel engine using pure soybean, cottonseed, and algae biodiesel fuels. A system level engine simulation tool developed by Gamma Technologies, GT-Power, has been used to perform predictive engine combustion simulations using direct-injection jet modeling technique. Various physical and thermodynamic properties of the biodiesel fuels in both liquid and vapor states are required by the GT-Power combustion simulations. However, many of these fuel properties either do not exist or are not available in published literatures. The properties of the individual fatty esters, that comprise a biofuel, determine the overall fuel properties of the biofuel. In this study, fatty acid profiles of the soybean, cottonseed, and algae methylester biodiesel fuels have been identified and used for fuel property calculations. The predicted thermo-physical properties of biodiesels were then provided as fuel property inputs in the biodiesel combustion simulations. Using the calculated biodiesel fuel properties and an assumed fuel injector sac pressure profile, engine emissions of the conventional diesel and biodiesel fuels have been predicted from combustion simulations to investigate emission impacts of the biodiesel fuels. Soybean biodiesel engine emissions, which include NOx, HC, CO and CO2, measured at various engine speeds and loads in actual combustion emissions tests performed in this study were also compared to those predicted by the combustion simulations.

Full text
Abstract:
Diesel engine emissions are a source of environmental concern. The use of vegetable oil based fuels, called biodiesels, lowers particulate emissions due to the increased oxygen content of the fuel. This study aims to further increase the oxygen content of biodiesel by oxidizing the fuel, analyzing the resulting product, and determining if favorable lubricity qualities result. Oxidation is performed in a non-catalytic vapor phase reactor at temperatures between 300–400°C. The product is characterized using various analyses including sulfuric acid solubility, density, gas chromatography, bomb calorimetry, and lubricity. Optimum blend ratios of the oxidized fuels in a low sulfur diesel fuel to obtain maximum lubricity are determined.

Full text
Abstract:
A single cylinder DI (direct injection) diesel engine equipped with common-rail injection system was used to investigate the combustion and emission characteristics of biodiesel fuels. Tested fuels were conventional diesel and biodiesels obtained from unpolished rice oil and soybean oil. The volumetric blending ratios of biodiesel with diesel fuel are set at 0, 10, 20 and 40%. Experimental results show that the peak injection rate is reduced as the mixing ratio increased. The effect of the mixing ratio on the injection delay of biodiesel is not significant at the equal injection pressure. The peak combustion pressure was increased with the increase of the mixing ratio at an injection pressure of 100MPa. The ignition delay became shorter with the increase of the mixing ratio due to a higher cetane number of the biodiesel. HC and CO emissions are decreased at a high injection pressure. However, NOx emissions are increased at higher mixing ratios.

Abstract:
The autoignition of fatty-acid methyl ester biodiesels and methyl ester biodiesel components was studied in gas-phase shock tube experiments. Ignition delay times for two reference methyl ester biodiesel fuels, derived from methanol-based transesterification of soybean oil and animal fats, and four primary constituents of all methyl ester biodiesels, methyl palmitate, methyl stearate, methyl oleate, and methyl linoleate, were measured behind reflected shock waves for fuel/air mixtures at temperatures ranging from 900 to 1350 K and at pressures around 10 and 20 atm. Ignition delay times were determined by monitoring pressure and chemiluminescence from electronically-excited OH radicals around 310 nm. The results show similarity in ignition delay times for all methyl ester fuels considered, irrespective of the variations in organic structure, at the high-temperature conditions studied and also similarity in high-temperature ignition delay times for methyl esters and n-alkanes.
