Book excerpt: Diesel engines are attractive power units that are used widely in many fields and have become one of the larger contributors of total petroleum consumption. However, diesel engines are among the main contributors to emissions into the air, especially particulate matter (PM) and nitrogen oxides (NOx). PM is one of the major pollutants emitted by diesel engines and has adverse effects on human health. However, not many studies have been conducted on the PM concentration and PM morphological and size distribution on biodiesel fuel. Biodiesel, which produces less PM than diesel fuel, is preferred as an alternative source for diesel engines. Therefore, using palm oil methyl ester (POME) for diesel engines would be a more economical and sustainable solution. The objective of this research is to study the PM emissions characteristic from diesel engines fuelled with a diesel and POME blend. A transmission electron microscope (TEM) was used to determine the aggregate fractal prefactor, spherule, and aggregate size distribution. A comparison between diesel and the POME blend was made in terms of PM characterization, which involves PM mass concentration, its components soluble organic fraction (SOF) and dry soot (DS), and its influence on PM morphology such as spherule and aggregate correlation. Combustion characteristics such as in-cylinder pressure and rate of heat release of the engine as well as gaseous emissions were also observed at different operating engine loads. The results show that PM emissions of B100 are lower than those of diesel fuel owing to the oxygen content of POME. Observations of images on PM morphology showed a chainlike agglomeration, which is an extremely small non-uniform nanostructure. Simultaneously, the aggregate size distribution shifted to a smaller diameter as the blending ratio of POME in the fuel increased. The observation of in-cylinder pressure showed that the increment of pressure with the increasing POME blend as well as the increasing engine load is due to high cetane number for B100 that led to a shorten ignition delay. The engine brake thermal efficiency between the POME blend and mineral diesel was comparable. Furthermore, B100 fuels showed lower engine power at higher brake-specific fuel consumption compared to other tested fuels. In terms of gaseous emissions, increasing POME blends led to an increase in CO2 and NOx while decreasing CO emission. Meanwhile, as the engine load increased, CO2, NOx and CO also continued to increase. The effect of the POME blend on the PM-NOx trade-off observation showed that B100 simultaneously increased the NOx and decreased the PM emission. Both the wavelet analysis and coefficient of variation revealed that increasing the POME ratio provided a noticeable effect on increasing the engine cycle-to-cycle variations. It can be concluded that POME creates lower PM concentration while giving some negative feedback to NOx and resulting in smaller particle size. Moreover, the findings reveal that by having the wavelet analysis, one can predict the behavior of the PM emissions and subsequently further research helps to reduce them effectively and economically.

The test fuels were 2%, 5%, 20% of rapeseed methyl ester, pure rapeseed methyl ester, 2%, 5%, 20% of palm stearin methyl ester, pure palm strearin methyl ester, 20%, 30%, 40% of used cooking oil methyl ester. Two kinds of test vehicles were Toyota D4D 2.5L and Isuzu DMAX 2.5L. The exhaust emissions analysis were carried out by running on chassis dynamometer. The results showed that the blends of 2%, 5% of palm strearin methyl ester and rapeseed methyl ester showed did not significant difference in exhaust emissions and fuel consumption compared to based diesel. In the other hand, the blends of 5% showed tendency reduction of THC and PM emissions. The blends of 20% with all kinds methyl ester, the THC, PM emissions were decreased 10-34% and 6-34% while the fuel consumption was increased 2-5%. Used cooking oil methyl ester blended with diesel in ratio 30, 40%were decreased THC, PM emissions 18-27% and 16-36%. NOX emissions and fuel consumption were increased 7%, 5-6%. Pure palm strearin methyl ester and rapeseed methyl ester provides a greater reduction of all exhaust emissions. On the contrary, NOX emission and fuel consumption were increased.

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.

This book was released on 2022-03-31 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technical Report from the year 2022 in the subject Engineering - Mechanical Engineering, , course: Mechanical, language: English, abstract: Biomass derived vegetable oils are quite promising alternative fuels for agricultural diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity. The performance of vegetable oils can be improved by modifying them through the transesterification process. In the present work, the performance of single cylinder water-cooled diesel engine using methyl-ester of Jatropha and Karanja oil as fuel was evaluated for its performance and exhaust emissions. The fuel properties of biodiesel such as kinematic viscosity, calorific value, flash point, carbon residue and specific gravity were found. Results indicated that B25 has closer performance to diesel and B100 has lower brake thermal efficiency, mainly due to its high viscosity compared to diesel. The brake thermal efficiency for biodiesel and its blends was found to be slightly higher than that of diesel fuel at tested load conditions and there was no difference between the biodiesel and its blended fuels efficiencies. For Jatropha and karanja biodiesel and its blended fuels, the exhaust gas temperature increased with increase in power and amount of biodiesel. But, diesel blends showed reasonable efficiency, lower smoke, CO2, CO and HC.

This book was released on 2015 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel engines which is an attractive power unit used widely in many fields are among the main contributors to air pollutions for the large amount of emissions, especially particulate matter (PM) and nitrogen oxides (NOx). PM is one of the major pollutants emitted by diesel engine which have adverse effects on human health. Accordingly, many research have been done to find alternative fuels that are clean and efficient. In this study, waste cooking oil (WCO) biodiesel has been used as an alternative source for diesel engine which produces lower PM than diesel fuel. The emission of PM and gaseous emission (carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO) and NOx) has been collected from single cylinder diesel engine fuelled with diesel and WCO biodiesel blends (B5, B10 B20 and B100) at five different engine speed (1200 rpm, 1500 rpm, 1800 rpm, 2100 rpm and 2400 rpm) with constant load of 20 Nm. The comparison between diesel and WCO biodiesel blends has been made in terms of PM characterization which is PM mass concentration, its component ( soluble organic fraction (SOF) and soot) and its influence on PM formation, PM morphology and PM size distribution. In addition, combustion characteristic which is in-cylinder pressure of the engine as well as exhaust temperature also has been observed. The results show PM emission of B100 is lower than diesel fuel with variation of 5.56% to 21.82 % . This is due to oxygen content contained in B100. As for SOF concentration, blended fuels B10, B20, and B100 have higher SOF value (3.23 % to 82.36 % ) compared to diesel fuel at moderate and high engine speed. Meanwhile, soot concentration for blended fuels B10, B20 and B100 is lower (10 % to 62.50 %. ) compared to diesel fuel Observation on PM morphology shows that the images is chain-like agglomeration which is extremely small non uniform nanostructure. As for the PM size distribution, the trend were similar for diesel and WCO biodiesel blends. The size distribution of diesel fuel and WCO biodiesel blends were shifted to the larger size as the engine speed is increase d. Simultaneously, the size distribution is shifted to the smaller PM diameter as blending ratio of WCO biodiesel in the fuel blend is increase. The observation of in-cylinder pressure shows uncertain trend with the WCO biodiesel ratio in the fuel blend while decreasing with the increasing engine speed due to the prolong ignition delay period. At the same time, WCO biodiesel blends gives higher value of exhaust temperature which is 1.49 % compared to diesel fuel and it increases as the engine speed increase. In terms of gaseous emission, increasing engine speed increased the CO, CO2, NOx and NO emission while decrease the O2emission. The effect of WCO biodiesel blends on the gaseous emission shows uncertain trend while PM-NOx trade off observation showsB100 simultaneously decrease both NOx and PM emission at the same time. This study shows that the PM and gaseous emission as well as combustion characteristic of the WCO biodiesel are comparable with diesel fuel thus WCO biodiesel has potential as an alternative fuel to be used in diesel in the future.
