Effects on Combustion of Gasoline of Rare Earth Composite Materials for Far Infrared Radiation

摘要

The rare earth composite materials (RECMS) for far infrared radiation were prepared using rare earth elements and natural mineral materials radiating far infrared. The effects of the granularity and rare earth additions on the far infrared radiation were investigated. The results show that the as-prepared composite materials with higher infrared radiance can enhance the combustion of gasoline, when the composite are about 4.24 μm in average granularity and comprise about 6% (mass fraction) of rare earth. Through bench test, the oil-saving rate of the engine dealt with the composite is 2.8%～3.7%, and the reducing rate of CO and HC in the exhaust gas is 20%～25% and 28%～30%, respectively.
