The ignition delay time (IDT) data reported in this article1 were recently found to be erroneous. Two issues caused errors in the previous data, (i) a fraction of the volatile fuel, diethyl ether (DEE), was lost during mixture preparation, and (ii) a fraction of the high boiling point fuel, ethyl levulinate (EL), was lost due to condensation on the walls of the combustion chamber. These issues were realized after the publication of the original paper while working on another project. After fixing these problems, we obtained new IDT results which deviated significantly from the previous data at low temperatures. New IDT data of the EtOH/DEE/EL blend showed NTC behavior, in contrast to previous data which primarily exhibited Arrhenius-like behavior. The revised Fig. 2 below plots the updated data, and these data are provided in tabular form in the ESI.(Figure presented). The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
