在電磁波光譜中，一般將波長介於0.75pm至lOOOmm的不可見光稱為遠紅外線，其中波長介於3mm至15mm的遠紅外線，對於生物的生長不可或缺，又被稱為「生育光線」或「生命光波」。遠紅外功能稀土複合材料可改變液化石油氣火燄顏色[2]，提高空氣中氧氣(02)利用率，並降低排放廢氣的ー氧化碳(CO)濃度，提高燃燒反應速率，並節省液化石油氣消耗7.5%。本文經由設計一組利用電氣石(tourmaline)產生遠紅外線(far infrared)負離子(negativeion )的活化(excitation)燃油裝置，透過三種實驗方式：（1).實際量測柴油機在不同負荷運轉下的排放廢氣成份分析比較，（2).國際標準實驗室化驗燃油成份結果分析比較，及(3).顯微鏡觀察燃油顆粒結果分析比較，以科學方式研究遠紅外線活化燃油的效果，定量分析排放廢氣的成份濃度改變。根據實驗結果，遠紅外線負離子具有改變市售「高級柴油」物理和化學性質的效果，並大幅降低柴油機排放廢氣汚染物，一氧化碳(CO)濃度約25%，氮氧化物(NOx)濃度約18%，碳氫化合物(HC)濃度約12%。

In the electromagnetic spectrum, the invisible light which wave length range from 0.75|im to lOOO^m, is usually known as far infrared. The far-infrared which wave length range from 3 jam to 15 pm, indispensable for the growth of organisms, is also called as the “Vital Rays” or “Light of life，，. The far infrared function of rare-earth mineral composite materials could lead to the change of Liquefied Petroleum Gas (LPG) flame color[2], the improvement of consumption of 0xygen(02)，and the reduced emission of carbon monoxide(CO). Through the improvement of combustion reaction, the specific consumption of LPG could be saved the 7.5%. The purpose of this report is to design and manufacture a device of far infrared therapy on the excitation of fuel oil by the composition of tourmaline. Through three kind of on-site experiment, (l).the measurement and analysis of emission of diesel engine running at different working load, (2).the analysis of fuel oil sample by International Standard Laboratory, (3).the observation analysis of fuel oil particles by microscopy, the effects of far infrared therapy on the emission of diesel engine and quantitative analysis of the constituent concentration changes of the emission by scientific research could be achieved. According to the experimental results, far infrared therapy could change the physical and chemical properties of commerciallv available fuel oil “Premium Diesel” and signiricantly reduced the emissions pollutants, the concentration of carbon monoxide (CO) about 25%, the concentration of nitrogen oxides (NOx) about 18%, and the concentration of hydrocarbons (HC) about 12%.
