Abstract
In order to utilize palm oil ethyl ester (PEE) as an alternative diesel fuel, the combustion characteristics and exhaust emissions are investigated using a small direct injection diesel engine, and are compared with palm oil methyl ester (PME), rapeseed oil ethyl and methyl esters (REE and RME) and the gas oil. As a result, PEE has lower pour point compared with PME. The thermal efficiency of PEE is almost the same as those of the other test fuels. PEE and PME have lower exhaust emissions compared with the other test fuels. Although CO and smoke emissions of PEE are slightly higher than that of PME, NO_x and HC emissions of PEE are almost the same as that of PME. It is concluded that PEE can be used as an alternative petroleum diesel fuel.
