We experimentally evaluate a performance and exhaust emissions of a single-cylinder, four stroke direct injection diesel engine operating on soybean waste food-oil, unused soybean food oil, waste animal fat, and rice oil methyl ester (Rice oil VDF). The combustion characteristics, emissions such as NOx, CO, THC, O_2, CO_2, smoke, particle size distribution and first stage durability test are compared with the case of JIS #2 diesel fuel. We found that (1) the NOx emissions of used soybean oil and Rice oil VDF are slightly higher than gas oil in the almost load range. (2) the CO emissions of Rice oil VDF are lower than base fuel in the over all. (3) Smoke emissions of used soybean oil, used animal fat and Rice oil VDF are lower than Gas oil especially at low load range.
