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 deposits on the cylinder head are observed after 150 hours. So, the Blend PS need to reduce the waste polystyrene pyrolysis oil.
