We experimentally evaluate a performance and exhaust emissions of a single-cylinder, four stroke direct injection diesel engine operating on Rice oil methyl ester (Rice oil BDF), Mixed waste food oil methyl ester (Recycle BDF), Recycle BDF adding 500wt ppm Ferrocene (Re-BDF+Fe) and adding 500wt ppm Cerium Mixed (Re-BDF+Ce). The combustion characteristics, emissions such as NOx, CO, HC, O_2, CO_2, smoke, particle size distribution and first stage durability test are compared with the case of JIS # 2 gas oil. We found that (1) the NOx emissions of Rice and Recycle BDF are slightly higher than gas oil in the almost load range. Though NOx emissions of BDF+Fe is as same as base fuel gas oil in the whole range. (2) CO and Smoke emissions of BDF fuels are lower than gas oil especially in the high load range. (3) PM emissions of Recycle BDF is 1/2 times its gas oil. In case of Re-BDF+Ce and Fe are higher than Recycle BDF.
