Download or read book Combustion and Emission Characteristics of Biofuels in Diesel Engines written by Lukasz Labecki and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was concerned with the performance of biofuels in diesel engines. Generally, the basic combustion and emission characteristics of Rapeseed Oil (RSO) and Soya Oil (SO) result in a lower in-cylinder pressure peak than diesel. This led to the reduction of Nitrogen Oxides (NOx) emissions and to relatively high soot emissions. Further measurements of RSO were done in order to investigate the influence of injection pressure, injection timing and Exhaust Gas Recirculation (EGR) on combustion and emission characteristics. A high soot emission from RSO was reduced by increased injection pressure. Moreover, injection timing also had to be varied in order to reduce the soot emissions from RSO. The retarded injection timing (3 deg bTDC) and increased injection pressure (1200 bar) for the blend of 30% RSO resulted in a reduction of soot emission to the same level as from diesel fuel. Further investigation regarding the soot emissions was done for Rapeseed Methyl Ester (RME) under turbocharged engine operation. The application of the boost pressure resulted in stable engine operation at a late injection timing of 5 deg aTDC. A simultaneous reduction of soot and NOx emissions has been achieved for RME at an injection timing of TDC and high EGR percentage (40-50%). The soot particles size distribution under different engine operating conditions for RME and diesel has also been investigated. Moreover, the characteristic of Electrostatic Mobility Spectrometer (EMS) and the design of primary dilution system have been provided in order to understand the influence of the dilution process and to obtain more real results. Generally, RME showed less particles concentration in the nucleation mode when compared to diesel. Moreover, high EGR caused a shift of the particles from the nucleation mode by agglomeration into the accumulation mode for both fuels. The effect of injection pressure could only be seen in the accumulation mode, where high injection pressure slightly reduced the concentration number. The soot emission was effectively reduced by the usage of the diesel particulate filter (DPF). For this purpose, the soot particles size distributions before and after the DPF have been measured at different engine speeds and loads. At low engine torque, the soot was effectively filtered while the operation under high engine loads resulted in low soot particle concentration especially in the nucleation mode, after the DPF.

Download or read book Combustion and Emission Characteristics of Biodiesel in Diesel Engines written by Ibrahim Said and published by LAP Lambert Academic Publishing. This book was released on 2015-01-05 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetable oils are green promising alternative fuels for diesel engines such as jatropha oil. When they are used in diesel engines, higher viscosity and lower volatility of vegetable oils causes problems in spray penetration, atomization and mixture formation. Blends of biodiesel and diesel oil by volume (B5, B20, B40, B70 and B100) are burned. We produced biodiesel with standard chemical and physical properties. A new biodiesel engine should be designed to burn biodiesel blends up to B100 according to biodiesel thermodynamic cycle is needed. Conventional diesel engines are not suitable to burn biodiesel efficiently. Combustion and characteristics of biodiesel and preheated oil are extensively furnished. Burning biodiesel reduces emissions of CO, CO2 and HC. Suggested biodiesel engine should be designed to reduce NOx. This book can be useful for engineers, researchers, technologists seeking biodiesel production, environmental scientists, and car manufacturers.

Download or read book Towards Sustainable Production and Use of Resources written by and published by UNEP/Earthprint. This book was released on 2009 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was produced by the Working Group on biofuels of the International Panel for Sustainable Resource Managemet. It provides an overview of the key problems and perspectives toward sustainable production and use of biofuels. It is based on an extensive literature study, taking into account recent major reviews. The focus is on so-called first generation biofuels while considering further lines of development. In the overall context of enhancing resource productivity, options for more efficient and sustainable production and use of biomass are examined. In particular, "modern biomass use" for energetic purposes, such as biomass used for (co-)generation of heat and power and liquid biofuels for transport, are addressed and related to the use of biomass for food and material purposes. Whereas improving the efficiency of biomass production plays a certain role towards enhancing sustainability, progress will ultimately depend on a more efficient use of biotic (and abiotic) resources (incl. for instance an increased fuel economy of car fleets), although a full consideration of all relevant strategies towards this end (e.g changing diets high in animal based foods and reducing food losses) is beyond the scope of this report.
