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) and soybean oil methyl ester (VDF). The combustion characteristics and emissions such as NOx,CO,HC,HCHO,O_2,CO_2 and smoke are compared with the case of JIS # 2 diesel fuel. We found that (i) the CO,HC,HCHO emissions of Blend PS are higher than Diesel fuel in the low load range, though the CO,HC,HCHO emissions of Blend PS are similar to diesel fuel in the high load range, (ii) the NOx emissions of Blend PS is higher than diesel fuel in the almost load range, and smoke emissions of Blend PS is higher than other fuels in the low load range, though smoke emissions of Blend PS is lower than other fuels in the high load range, (iii) thermal efficiency of Blend PS is lower than diesel fuel and fuel consumption of Blend PS is higher than diesel fuel in the whole engine operating range.
