Palm oils or waste palm oils are blended with kerosene for wide vary called bensin irex. Both of these fuels are a controversy for run diesel engines. This paper was found out the cetane number of bensin irex to substitute the diesel fuel. The petroleum laboratory analyzed of specification of bensin irex and then this specification used to calculate the cetane number. The data of diesel fuel compared to the data of bensin irex, kerosene, straight palm oils, and waste palm oils. Cetane number of bensin irex was feasible to substituted diesel fuel. Palm or waste palm oil blended with kerosene has a linear effect to cetane number. 60% and higher composition of waste palm oil was suggested used for low rotation rate of diesel engines.

This project was funded by Young Lecturer Program of DIPA of Coordinator Private College Region VI Middle of Java in 2007.
