Final Report Summary - 2G-CSAFE (Combustion of Sustainable Alternative Fuels for Engines used in aeronautics and automotives)

The kinetics of oxidation of alcohols, methyl esters, ethyl esters, valerates, furanics, branched hydrocarbons, in relation to synthetic jet fuels, have been studied experimentally. Pollutants formation from the oxidation/combustion of biofuels and blends with conventional fuels has been characterized. The results showed that biofuels combustion can lead to an increased formation of pollutants, e.g., soot, polyaromatic hydrocarbons, aldehydes.
A new experimental set-up consisting of a Jet-Stirred Reactor, a sampling cone and a Cavity Ring-Down Spectrometer has been built to measure H2O2 and the HO2 radical which is of major importance for understanding fuels ignition and improving combustion models.
An extensive combustion kinetics database has been obtained that allows improving combustion models.
Using a micro flow reactor with advanced diagnostics, we have determined the ignition characteristics of several hydrocarbons (methane, ethylene, acetylene) during single and multi-stage ignition. An extensive database has been obtained and new combustion dynamics have been observed.
We have studied the potential of HCCI plasma-assisted ignition-combustion control by adding small amounts of active species separately and mixed (NO, NO2, O3). An extensive database has been obtained for enhanced combustion of hydrocarbons and alcohols. Modeling has been performed to interpret the experimental results. Interesting operating conditions have been delineated.
We have performed ab initio calculations to determine the decomposition pathways and the associated kinetic parameters of several potential biofuels. These parameters were very useful for improving the kinetic reaction mechanisms proposed for the oxidation of a wide range of fuels. New comprehensive kinetic models have been developed for an extended range of chemical classes in relation to 2G-biofuels combustion and conventional fuels. The oxidation of fuels perturbed by ozone, NO and NO2 has been modeled too.
Further information on the project output can be found on the project website (http://2g-csafe.eu) where updates will be published (publications from the project, data, and models).
