abstract

The autoignition of three biodiesel surrogates (methyl decanoate, methyl 9-decenoate, and a mixture of methyl 5-decenoate and methyl 6-decenoate), representative of the organic structures found in fatty-acid methyl ester (FAME) biodiesels, has been studied using the reflected shock technique. Measurements of ignition delay times were carried out at 20 atm for temperatures ranging from 700 to 1300 K, spanning all three regimes of reactivity of interest to diesel engines. At high temperatures (> 900 K) the three surrogate components have indistinguishable ignition delay. While in the negative-temperature-coefficient (NTC) and low-temperature regimes (< 900 K) the deviation in ignition delay based on the location of the double bond with the methyl decenoate carbon chain is around a factor of two. The results show that location of double bonds within FAME biodiesel components will have an important role in governing the NTC and low-temperature reactivity for FAME biodiesels but is unimportant at high-temperatures, of significance for the development of biodiesel surrogates and modeling strategies for diesel engine simulations.
