Abstract

This study investigates the Glycine max (soybean oil) biodiesel with hydrogen along with MgO nanoadditives on compression ignition engines. A series of tests conducted at various loading conditions in a water-cooled, single-cylinder, constant-speed engine. The biodiesel blended soya oil was used as the primary fuel and hydrogen was added at a constant volume of 25 LPM. Additionally, MgO nanoparticles were dispersed to the blends at concentrations of 50 ppm. In this study, it was found that the addition of hydrogen to the CI engine resulted in an increase in combustion performance. In addition, hydrogen and oxygen molecules significantly reduced the exhaust gas temperature and brake specific fuel consumption of biodiesel samples. An increase in nanoparticle concentration resulted in a reduction in emissions of pollutants such CO2, CO and HC. Inclusion of the hydrogen to the combustion chamber reduces the carbon content burned. Further, the availability of extra molecules in the MgO aids the fuel to reach higher combustion rates. At higher load conditions, biodiesel blends showed slight decrease in NOx emissions. Overall, from the findings it is clear that hydrogen addition and nanoparticles enhanced emission and combustion process, which is attributed due to increase in hydrogen content in the fuel.

添加纳米添加剂和氢气的甘氨酸max生物柴油混合物的发动机性能和排放特性预测
本研究研究了在压燃式发动机上添加氢气和氧化镁纳米添加剂的甘氨酸max(大豆油)生物柴油。在水冷、单缸、定速发动机的各种负载条件下进行的一系列试验。使用混合了生物柴油的大豆油作为主要燃料,并以25LPM的恒定体积添加氢气。此外,将MgO纳米颗粒以50ppm的浓度分散到共混物中。在这项研究中,发现在CI发动机中添加氢气可以提高燃烧性能。此外,氢和氧分子显著降低了生物柴油样品的废气温度和制动器比油耗。纳米粒子浓度的增加导致CO2、CO和HC等污染物的排放减少。将氢气包含在燃烧室中可减少燃烧的碳含量。此外,MgO中额外分子的可用性有助于燃料达到更高的燃烧速率。在较高负载条件下,混合生物柴油的NOx排放量略有下降。总的来说,从研究结果可以清楚地看出,氢的添加和纳米颗粒增强了排放和燃烧过程,这归因于燃料中氢含量的增加。
