In order to use palm oil methyl ester (PME) as a base fuel of the biodiesel, PME with 1-butanol (BPME) is tested using a DI diesel engine. The 1-butanol content in BPME is 10 to 30mass%. There is no problem in the startability and stability of the engine operation with BPME. Thermal efficiency of BPME is almost the same as that of PME and JIS no.2 gas oil. Although BPME has longer ignition delay compared with PME due to the low cetane number of 1-butanol, the combustion end timing of BPME is same. The smoke emissions of BPME decrease with increasing 1-butanol content although the HC and CO emissions increase due to the longer ignition delay. When the 1-butanol content in BPME is 15mass%, BPME has almost the same ignition delay and HC and CO emissions compared with the gas oil. From the experimental results, it is concluded that PME is better than RME as a base fuel of the biodiesel with 1-butanol due to the better ignitability and lower exhaust emissions of BPME.
