The cetane number, a widely used diesel fuel quality parameter related to the ignition delay time and combustion quality of a fuel, has been applied to alternative diesel fuels such as biodiesel and its components. In this work, the cetane numbers of two samples of euphorbia antiquorum and cissus qudrangularsis were determined. The cetane numbers of these samples which improve the properties of biodiesel can be employed without greatly influencing ignition properties compared to the more common euphorbia antiquorum and cissus qudrangularsis.cetane numbers were determined in an ignition quality tester(IQT)which is a newly developed, to determine a cetane number aniline point apparatus method using only small amounts of material. The IQT is as applicable to biodiesel and its components as previous cetane-testing methods. Reported values of the cetane number for biodesel vary widely. For the euphorbia antiquorum and cissus qudrangularsis oil-derived biodiesel, the values range from 17 to as high as 24.some of this variation may be due to differences in the biodiesel composition of the euphorbia antiquorum and cissus qudrangularsis samples but other factors are also important. This paper reviews development of the cetane number test procedure and its current status.it discusses the existing data for the cetane number of biodiesel and presents new data for the effect of the fuel quality composition of ignition delay time and for the fuel.
