Abstract

In order to reduce the pour point of palm oil biodiesel, palm oil butyl ester (PBE) is made with 1-butanol by transesterification. As a result, the pour point of PBE is 5.0°C and it is lower than that of palm oil methyl ester (PME), 12.5°C. The combustion characteristics and exhaust emissions of PBE are investigated using a direct injection diesel engine, and are compared with PME, rapeseed oil methyl ester (RME) and JIS No. 2 gas oil. The thermal efficiency of PBE is almost the same as those of the other test fuels. PBE has good ignitability as PME. Although HC, CO and smoke emissions of PBE are slightly higher than that of PME, PBE has lower exhaust emissions compared with the gas oil. Also, smoke emission of PBE is almost the same as that of RME. It is concluded that PBE is a good alternative diesel fuel.
