摘要

摘要生物柴油混合物的冷滤点（CFPP）值需要提高，因为据报道，在寒冷气候下使用高浓度的生物柴油混合物会导致重大问题。因此，本研究的主要目的是利用乙基己醇添加剂提高生物柴油共混物的CFPP值。它也是为了检查混合物的燃烧和排放行为。将生物柴油混合物制备为：；5%乙基己醇-10%生物柴油-85%超低硫柴油（ULSD）命名为E5B10，5%乙基己酯-20%生物柴油-75%ULSD命名为E5B20燃料。在1500转/分钟的恒定发动机转速和四种不同负载（怠速、1、2和3 bar BMEP）。与ULSD相比，由于SOC晚约1˚，EOC早约2˚，乙基丙糖醇的添加导致缸内压力和温度降低。在低负载和高负载下，与ULSD相比，压力上升率略高，相差约1 巴/度。因此，这些具有改进的CFPP值的共混物可以在寒冷气候下使用。

Effects of ethyl proxitol (1-ethoxy-2-propanol) additive on combustion and emission characteristics of biodiesel blends

Abstract The cold filter plugging point (CFPP) value of biodiesel fuel blends need to be improved because of it has been reported that utilizing high concentrations of biodiesel blends in cold climates can cause major issues. Therefore, the main objective of the study is to improve CFPP value of biodiesel blends using ethyl proxitol additive. It is also to examine combustion and emission of the blends behavior. Biodiesel blends were prepared as; 5% ethyl proxitol-10% biodiesel-85% ultra-low sulfur diesel (ULSD) named as E5B10 and 5% ethyl proxitol-20% biodiesel-75% ULSD named as E5B20 fuel. These fuel blends were compared with ULSD fuel in a compression ignition engine at a constant engine speed of 1500 rev/min and four different loads (idle, 1, 2, and 3 bar BMEP) of eddy current dynamometer. The addition of ethyl proxitol led to a decrease in in-cylinder pressure and temperature due to an about 1˚ later SOC and 2˚ earlier EOC compared to ULSD. The pressure rise rate was slightly higher compared to ULSD at both low and high loads, with a difference of about 1 bar per degree. As a result, these blends with improved CFPP value can be used in cold climates.

期刊介绍： Current energy systems need a vast transformation to meet the key demands of the 21st century: reduced environmental impact, economic viability and efficiency. An essential part of this energy revolution is bioenergy. The movement towards widespread implementation of first generation biofuels is still in its infancy, requiring continued evaluation and improvement to be fully realised. Problems with current bioenergy strategies, for example competition over land use for food crops, do not yet have satisfactory solutions. The second generation of biofuels, based around cellulosic ethanol, are now in development and are opening up new possibilities for future energy generation. Recent advances in genetics have pioneered research into designer fuels and sources such as algae have been revealed as untapped bioenergy resources. As global energy requirements change and grow, it is crucial that all aspects of the bioenergy production process are streamlined and improved, from the design of more efficient biorefineries to research into biohydrogen as an energy carrier. Current energy infrastructures need to be adapted and changed to fulfil the promises of biomass for power generation. Biofuels provides a forum for all stakeholders in the bioenergy sector, featuring review articles, original research, commentaries, news, research and development spotlights, interviews with key opinion leaders and much more, with a view to establishing an international community of bioenergy communication. As biofuel research continues at an unprecedented rate, the development of new feedstocks and improvements in bioenergy production processes provide the key to the transformation of biomass into a global energy resource. With the twin threats of climate change and depleted fossil fuel reserves looming, it is vitally important that research communities are mobilized to fully realize the potential of bioenergy.
