Modelling and Analysis of the Combustion of aeronautics fuels and Alternative Hydrocarbons in Conventional and Hybrid Compression Ignition engines – MACH2
To reach the objectives set by the ACARE European Commitment to reduce drastically CO2 and nitrogen oxide emissions, but also noise of the air transport sector in 2020, the aeronautics industry is looking forward breakthrough powertrain technical solutions. For light aircrafts (helicopters, general and business aviation aircrafts, drones...) or for auxiliaries power units (APU) in airliners, one of the considered technical solutions consists in using highly supercharged Diesel Internal Combustion Engines (ICE's), eventually embedded in an hybrid powertrain. The optimization of these complex technical solutions as far as performances, fuel consumption, pollutant emissions and noise are considered, in steady state but also in transient operating conditions (notably for engine restart), is a common interest point between aeronautics and automotive transport sectors. In this very restricted context, it is essential to well understand and manage the impact of physical and chemical properties of fuel on the ICE behaviour. This is so much important as far as aircraft fuels are considered, because their properties are very different compared to the conventional automobile Diesel fuel ones and because aircraft fuels cover a very large panel of chemical products. Commonly, the knowledge of combustion with light fuels is essential to evaluate the impact of the use of alternative fuel in automotive and aeronautics sectors. The MACH2 project aims to develop and use tools to improve knowledge and conception of Diesel ICE operating with light fuels (aircraft and alternative fuels for automotive and aeronautics sectors). These tools will be the result of a research study coupling experimental studies, detailed 3D simulations of Diesel thermodynamic cycles, carried out in steady state and transient operating conditions on a highly boosted single cylinder engine capable of very high specific performances. The objective is to cover the whole applications of automotive and aeronautics sector. This study will be based on fundamental experimental study about auto-ignition kinetic characterisation, pollutant formation, injection and Diesel spray evolution.
