Book excerpt: This report summarizes the results of a 3-year project lead by the Naval Facilities Engineering Service Center (NFESC) to obtain emissions factors (i.e. tailpipe air pollution emissions data) from 10 types of Department of Defense (DoD) operated diesel powered engines. Emissions data was obtained from 8 vehicles, primarily buses and trucks, and 2 portable generators. All testing was performed with the engines installed in the vehicles/portable equipment. Emissions factors were determined for the engines fueled with various blends/types of biodiesel as well as a baseline fuel, either California Air Resources Board (CARB) certified Ultra Low Sulfur Diesel (USLD) (15-ppm sulfur maximum) or JP-8. CARB USLD was used since it will be required within California for on-road vehicles starting in June 2006. Biodiesel blends from 20% to 70% were tested along with 100% biodiesel. For the blended biodiesel testing, the biodiesel was mixed with USLD. Although several blends were tested, the project focused on B20 (20% biodiesel) blends, since this is the primary blend of biodiesel used in military vehicles. Testing performed on B20 fuels identified three significant results: (1) There were no consistent trends over all engines tested, (2) There were no statistically significant emissions differences found between biodiesel fuels manufactured from yellow grease or soy bean oil feedstocks, and (3) An extensive statistical analyses indicated no statistically significant differences in Hydrocarbon (HC), Carbon Monoxide (CO), Nitrogen Oxides (NOx) or Particulate Matter (PM) emissions between a B20 biodiesel manufactured at Naval Base Ventura County from yellow grease and CARB ULSD petroleum diesel. The results from this project are significantly different than those previously reported by the Environmental Protection Agency (EPA). Of particular interest is the fact that for actual DoD fleet diesel engines, there was no statistically significant increase in NOx emissions.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasingly strict emissions regulations along with man-made global warming has peaked interest in clean burning diesel engines. Renewable biofuels such as biodiesel are being investigated to reduce carbon monoxide (CO), unburned hydrocarbon (HC), and smoke opacity, while slightly increasing nitrogen oxides (NOx). Two modern diesel engines, a light-duty engine and heavy-duty engine, were investigated with various biodiesel blends. The heavy-duty engine was a Cummins 4-cylinder direct injection (DI) diesel engine, which was run at three idling conditions: low, medium and high idling states operated at 800 revolutions per minute (rpm), 1000 rpm, and 1200 rpm respectively. The engine was fueled with biodiesel-diesel blends with two additives. Two additives, ethanol and diethyl ether (DEE) at 5% and 15% were mixed with biodiesel-diesel blends B20, B50 and B100. B100 was produced from canola oil. The engine was tested from cold start to warm up in real world conditions. The light-duty engine was a HATZ 2-cylinder diesel engine, which was fueled with biodiesel blends with dissolved expanded polystyrene (EPS) and fuel stabilizer additive acetone. The light-duty engine was tested at three speed conditions 1000 rpm, 2100 rpm, and 3000 rpm. Each speed condition had 4 load conditions: 0%, 20%, 50%, and 80% load. EPS was dissolved at 50g/l of biodiesel and the acetone additive was tested at 100ml/l of biodiesel and 250ml/l of biodiesel. Emissions analysis was conducted for carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), oxides of nitrogen (NOx), smoke opacity and unburned hydrocarbons (HC). Investigation results demonstrate that for the heavy-duty engine at idle conditions, diesel-biodiesel blends with additives produce lower CO emissions than neat diesel. Ethanol and DEE additives can also reduce NOx emissions in diesel-biodiesel blends, and increasing biodiesel content reduced HC emissions. For the light-duty engine at all loading conditions biodiesel-diesel blends produced lower CO emissions, higher NOx emissions and higher smoke opacity. EPS content overall decreased CO and NOx emissions, but increased smoke opacity. At 100ml/l of biodiesel acetone decreased CO emissions, acetone at 250 ml/l of biodiesel increased CO emissions. Acetone increased NOx emissions and decreased smoke opacity.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiesel has been suggested as an alternative fuel to the petroleum diesel fuel. It beneficially reduces regulated emission gases, but increases NOx (nitric oxide and nitrogen dioxide) Thus, the increase in NOx is the barrier for potential growth of the biodiesel fuel. In general, NOx formation is dominated by flame temperature. Interestingly, soot can play a role as a heat sink as well as a heat transfer media to high temperature gases. Thus, the cooling effect of soot may change the flame temperature and therefore, NOx emissions. In this study, emphasis is placed on the relationship between soot and NO (Nitric oxide) formation. For the experimental study, a metallic fuel additive is used since barium is known to be effective to suppress soot formation during combustion. The barium additive is applied to #2D (Number 2 diesel fuel) by volume basis: 0.1, 0.25 and 0.5 %-v, and to the palm olein oil by 0.25 %-v. All the tests are carried out in a four-cylinder medium duty diesel engine, 4045 DI diesel engine, manufactured by John Deere. For the analysis, an analytical model is used to estimate combustion temperature, NO concentration and soot emissivity. The results show that NO concentration does not have the expected trade-off relation with soot. Rather, NO concentration is found to be more strongly affected by ambient temperature and combustion characteristics than by soot. The results of the analytical model show the reasonable NO estimation and the improvement on temperature calculation. However, the model is not able to explain the detailed changes of soot emissivity by the different fuels since the emissivity correlation is developed empirically for diesel fuel.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing concerns over environmental issues and conventional resource depletion have heightened our motivation to use clean and alternative fuels. Biodiesel is simply derived from biomass proposed as an alternative fuel for diesel engines, which contributes to a reduction in carbon monoxide (CO), smoke intensity, and unburned hydrocarbon (HC). However, biodiesel has inferior cold flow properties and emits higher nitrogen oxides (NOx) compared to conventional diesel. The present work aims at improving cold flow properties of biodiesel using the fractionation method combined with additives, and investigates their effects on a diesel engine's regulated emissions and performance. In addition, emulsion fuels were found to reduce both NOx emission and smoke intensity. Experiments using urea, mixture of recovered urea and crystal, and crystal fractionation were conducted; the additives include ethanol, methanol, and diethyl ether (DEE). Results using two modern diesel engines (a light-duty and a heavy-duty) were investigated using various fuels. The heavy-duty engine was fueled with different fuel types and eight emulsion fuels at two idling conditions (1200 rpm and 1500 rpm). The light-duty engine was fueled with biodiesel blends, fractionated biodiesel blends, emulsified diesel-biodiesel, emulsified diesel-biodiesel ammonium hydroxides blends, and emulsified biodiesel at three different engine operating conditions. The conclusion was that a mixture of recovered urea and crystal fractionation provided higher production efficiency and acceptable cloud point. A significant reduction in NOx emission was obtained from emulsified fuels compared with their bases, and emulsion biodiesel with 2.5% water revealed results that were comparable to diesel in terms of NOx and CO emissions at all engine operating conditions.

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.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The increase in world population has led to the growth in energy demand. The primary sources of this energy come from the combustion of conventional fuels, which are contributing to polluting the environment. Biodiesel offers a solution as an alternative fuel for internal combustion engines, however it emits higher (nitrogen oxides) NOx emission. Exhaust gas recirculation (EGR) systems, as well as methods that supply steam into the intake air system of diesel engines, are used to lower NOx emissions. This study focuses on determining the effects of EGR, methods that supply steam into the intake air systems, canola biodiesel, and emulsions consisting of diesel-biodiesel blends with additives on diesel engine performance and emissions. Experiments using two modern diesel engines (a light-duty and a heavy-duty) were investigated at various operating conditions. The results showed that canola biodiesel increased fuel consumption and NOx, but decreased other emissions including carbon monoxide (CO) and hydrocarbon (HC) emissions. The use of both EGR, methods that supply steam into the intake air system, and emulsion consisting of diesel-biodiesel blend with diethyl ether (DEE) showed a significant reduction in NOx emission and exhaust temperature; however, there were slight increases in fuel consumption, CO, and HC emissions.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-road diesel engines are significant contributors to air pollution in the United States. Recent regulations put forth by EPA and other environmental agencies have laid out stringent guidelines for engine manufacturers and fuel producers. Recent increases in oil prices and foreign energy dependency has led to a push to produce renewable fuels, which will supplement current reserves. Biodiesel is a clean-burning renewable fuel, that can be blended with petroleum diesel. It is important to understand the effect on engine performance and exhaust emissions when using biodiesel from different feedstocks. The objective of this research was to determine the relationship between engine performance and emissions and cottonseed oil biodiesel used in a diesel engine rated for 14.2 kW. When using cottonseed oil biodiesel blends, CO, hydrocarbon, NOx, and SO2 emissions decreased as compared to petroleum diesel. Carbon dioxide emissions had no definitive trend in relation to cottonseed oil biodiesel blends. Carbon monoxide emissions increased by an average 15% using B5 and by an average of 19% using B100. Hydrocarbon emissions decreased by 14% using B5 and by 26% using B100. Nitrogen oxide emissions decreased by four percent with B5, five percent with B20, and 14% with B100. Sulfur dioxide emissions decreased by an average of 86% using B100, and by 94% using B50 blended with ultra-low sulfur diesel. The difference between peak output power when using biodiesel and diesel was insignificant in blends less that B40. Peak measured power using B100 was about five percent lower than for diesel fuel. Pure cottonseed oil biodiesel achieved and maintained a peak corrected measured power of 13.1 kW at speeds of 2990, 2875, and 2800 rpm at loads of 41.3, 42.7, and 43.8 N-m. Using B5 produced a peak power of 13.6 kW at 2990 rpm and 43.9 N-m and at 2800 rpm and 46.7 N-m, while using B20 produced a peak power of 13.4 kW at 2990 rpm and 43.7 N-m. Brake-specific fuel consumption at peak measured load and torque using B100 was 1238 g/kW-h. Brake-specific fuel consumption at peak measured power and loads using B5 and B20 were 1276 and 1155 g/kW-h.

Book excerpt: This document reviews recent literature regarding the usage of biodiesel and biodiesel blend fuel in on road applications. The report describes some of the principal characteristics of biodiesel and usage experience in and near the State of Montana. Several studies are summarized regarding biodiesel's effects on engine performance and warranties. Storage, handling and transportation requirements are also discussed. The emissions related impacts of biodiesel on several pollutants are quantified, along with potential effects of these impacts on the state and vehicle users within the state. The legislative environment regarding biodiesel and existing motor fuel taxes, at a Federal level and in other states, is reviewed. Considerations regarding fuel cost and domestic productive capacity are discussed. The report concludes that most technical questions regarding biodiesel appear to be satisfactorily answered; the primary obstacles limiting broader biodiesel implementation relate to cost and user acceptance.
