Several different ether components have been proposed as renewable replacements for diesel fuel in compression ignition engines. From a fundamental point of view, blends of n-heptane and dimethyl ether (DME) have been considered in this study, where

n-Heptane has been used extensively in various fundamental combustion experiments as a prototypical hydrocarbon fuel. While the formation of polycyclic aromatic hydrocarbon (PAH) in n -heptane combustion has been studied preferably in premixed flames

Blending petroleum-based fuels with biofuel components is deemed attractive to reduce soot and CO2 emissions, but fundamental studies of the combustion behavior of such fuel blends suited for model development and validation remain rather scarce. To

International audience; Di-n-butyl ether (DBE, C8H18O) has been proposed as a promising biofuel for diesel engines, but details of its low-temperature (LT) oxidation chemistry are not well understood. This paper reports new speciation data obtained i

International audience; Diethyl ether (DEE) has been recently suggested as a potential biofuel for compression-ignition engines that are known to be significantly controlled by low-temperature (LT) chemistry. However, the LT oxidation of DEE has not

The combustion chemistry of di-n‑butyl ether (DBE, C8H18O), conceivable as a potential biofuel candidate, was studied here for the first time under flame conditions with examining a detailed species dataset. Two flames, i.e., a fuel-rich (ϕ = 1.5)
