311 リサイクル燃料ディーゼル機関の性能と排ガスの環境特性(長期試験結果と PM の粒子径分布)

抄録

We experimentally evaluate a performance and exhaust emissions of a single-cylinder, four stroke direct injection diesel engine operating on diesel fuel containing 50% volume waste food-oil (Blend 50), waste food-oil containing 50% waste polystyrene pyrolysis oil (Blend PS), diesel fuel containing 30% and 40% volume waste polystyrene pyrolysis oil (Blend3P, 4P), soybean oil methyl ester (VDF) and Low Sulfur Diesel fuel (LS Diesel fuel). The combustion characteristics, emissions such as NOx, CO, HC, HCHO, O_2,CO_2,smoke, particle size distribution and first stage durability test are compared with the case of JIS#2 diesel fuel. Experimental results indicate that the Blend 50 and VDF are usable as alternative fuel for diesel engine and the manufactures of VDF and Blend 50 are available for a treatment process of the waste food-oil. The Blend PS is unsuitable for the diesel engine because carbon deposit heaped up combustion chamber with the progress of operating hours. So, The Blend PS need to reduce the waste polystyrene pyrolysis oil.
