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) as tested fuels. The combustion characteristics, emissions such as NOx, CO, smoke were compared with the case of JIS # 2 diesel fuel. Experimental results indicated that the Blend 50 were usable as alternative fuel for diesel engine and Blend 50 were available for a treatment process of the waste food-oil. In present study, fuel additives such as cetane improver and combustion improver were used for improving the combustion efficiency and reducing the unburned component in exhaust.
