Abstract

The quest for energy efficiency systems is gaining momentum in the present-day context due to prevailing environmental and eco nomic compulsions. One of the alternatives available to meet this requirement is to modify the fuel to make it greener and more reasonable. In the present study, an attempt has been made to assess the performance and emissions of a compression ignition (CI) engine fuelled with B20 biodiesel and nano additives. Experiments have been carried out on a ssingle-cylinder CI engine using waste cooking oil-derived biodiesel, B20 and nano-sized biochar and multi-walled carbon nano tubes (MWCNTs). The nano additives were used in concentrations of 20 and 40 ppm to form four fuel variants, and the results relating to performance and emissions were compared. B20 fuel with MWCNT nanoparticles showed better brake thermal efficiency (BTE), brake-specific fuel consumption and reduced HC and carbon monoxide emissions. On the contrary, increased exhaust temperature and a subsequent increase in NOx emissions were recorded. The activated biochar nanoparticles improved the BTE of the engine with a comparatively better removal of NOx. This intricate behaviour of both the carbon nanoparticles reported in this work requires comprehensive optimization studies in the future.

环保型纳米添加剂与绿色燃料对压缩点火发动机性能和排放的影响

由于当前的环境和经济压力，对能源效率系统的追求正在获得动力。满足这一要求的替代方案之一是修改燃料，使其更环保、更合理。在目前的研究中，我们试图评估使用B20生物柴油和纳米添加剂的压缩点火(CI)发动机的性能和排放。利用废弃食用油衍生的生物柴油、B20、纳米生物炭和多壁碳纳米管(MWCNTs)在单缸CI发动机上进行了实验。将纳米添加剂在浓度为20和40 ppm的情况下使用，形成四种燃料变体，并比较其性能和排放的相关结果。MWCNT纳米颗粒的B20燃料具有更好的制动热效率(BTE)，制动油耗和减少HC和一氧化碳排放。相反，废气温度升高，氮氧化物排放量随之增加。活性生物炭纳米颗粒提高了发动机的BTE，并具有相对较好的NOx去除效果。这两种碳纳米颗粒在这项工作中报道的复杂行为需要在未来进行全面的优化研究。
