This project aims at promoting sustainable combustion technologies for transportation by the validation of advanced combustion kinetic models obtained via the combined use of sophisticated new laboratory experiments, engines experiments, and theoretical computations, breaking through the current frontier of knowledge. It will focus on the unexplored kinetics of ignition and combustion of 2nd generation (2G) biofuels and blends with conventional fuels, which should provide energy safety and sustainability to Europe. The motivation is that no kinetic models are available for the ignition, oxidation and combustion of 2G-biofuels, and improved ignition control is needed for new compression ignition engines. Information on pollutants formation by combustion of 2G-biofuels and data obtained in well characterised experiment for their combustion are mostly missing. Finally, concentration measurements of key-intermediates for fuels’ ignition in new engines are missing.
It is proposed to provide that missing knowledge using new well-instrumented complementary experiments and kinetic modelling. Measurements of labile key-intermediates, stables species, and pollutants will be performed. New ignition control strategies, including plasma-assisted active control, could be more useful will be designed, opening new technological horizons. Kinetic modelling will be used for rationalising the results. Due to the complexity of renewable liquid fuels and their unusual composition, innovative surrogates will be designed for the modelling. Kinetic models for surrogate fuels will be generalised for extension to other compounds. The experimental results, together with ab-initio and detailed modelling, will serve to characterise the kinetics of ignition, combustion, and pollutants formation of fuels including 2G biofuels, and provide relevant data and kinetic models.
