摘　　要：根据电磁学理论中粒子的运动规律,具有逆磁和顺磁特性的氮气与氧气在强磁场中会受到不同方向的磁场力作用,使空气中的O2浓度增大、N2浓度下降.对进气口安装了磁环组装置的发动机进行排放试验,测试尾气中CO,HC和NOx的浓度.结果表明,安装磁环组装置后排放物中NOx浓度减少了近50%,同时CO和HC的浓度也有所降低.另外,随着发动机转速的增大,安装磁环组装置后排放物中NOx浓度反而有所增大,说明进气的速度对结果有影响.可见该装置应用于经常在低速、大负荷状态下工作的中小型内燃机有比较好的可行性.According to the law of particle movement in electromagnetic theory, the diamagnetic nitrogen and paramagnetic oxygen in the high-magnetic field will result in a counter-magnetizing force that acts on these gases, causing the increase of oxygen concentration and the decrease of nitrogen concentration. Through testing the concentration of CO,HC and NOx in the emission of Engine Emission Testing, in which the magnetism loop group be installed in the air intake. The results show that the testing installing the magnetism loop group, the concentration of NOx cuts down nearly 50%, and the CO and HC also decrease to a certain degree. In addition, while the engine speed accelerates, with the magnetism loop group the concentration of NOx in emission rises, which shows that the admission velocity has a significant effect on this device. Therefore, this device has better feasibility when applied to the small and medium engines which usually work in low speed and heavy load.
