Abstract

The impacts of strengthening magnetic field exposure on combustion performance of low-octane fuel have been examined experimentally. The combustion test was carried out using a 2-stroke 49 cc engine where the fuel was magnetized using a low magnetic field (<2 kG). Moreover, the molecular behavior of magnetized fuel was also characterized through spectrum tests using NIR and UV-Vis spectrophotometers. The result of this study indicates an exponential decrease of magnetized fuel consumption against the strengthening of magnetic field exposure. This exponential decrease of consumption can be related to the Arrhenius principle. In addition, the decrease of oxygen in the exhaust gas along with the strengthening of the magnetic field also confirms the increase of combustion reactions. Meanwhile, the increase of magnetized fuel absorption against ultraviolet and near-infrared lights along with the increase of the magnetic field intensity indicates a bond weakening, accompanied by the increase of molecular vibrational energy.

磁场强化对二冲程发动机低辛烷值燃油燃烧性能的影响

实验研究了强化磁场暴露对低辛烷值燃料燃烧性能的影响。燃烧测试使用一台2冲程49cc发动机进行，其中燃料使用低磁场(< 2kg)磁化。此外，还利用近红外光谱和紫外可见分光光度计对磁化燃料的分子行为进行了表征。本研究结果表明，随着磁场暴露强度的增强，磁化燃料消耗量呈指数下降。这种消费的指数下降与阿伦尼乌斯原理有关。此外，随着磁场的增强，废气中氧气的减少也证实了燃烧反应的增加。同时，磁化燃料对紫外和近红外光的吸收量随着磁场强度的增加而增加，表明化学键减弱，同时伴随着分子振动能的增加。
