After a very successful tenth anniversary of the biennial THIESEL Conference on Thermo-and Fluid Dynamic Processes in Direct Injection Engines in 2018, we are ready to enter in the new decade with renewed enthusiasm for ICE engines by celebrating THIESEL 2020 in September 2020.   

In spite of the very tough environmental demands, combustion engines will probably remain the main propulsion system in transport for the next 20 to 50 years, at least for as long as alternative solutions cannot provide the fl exibility expected by customers of the 21st century. But it needs to adapt to the new times, and so research in combustion engines is nowadays mostly focused on the new challenges posed by hybridization and downsizing.

THIESEL 2020 is the perfect event for industry, research institutions and academia to exchange high-tech knowledge and experience on topics related to R&D recent progress leading to engine concepts adapted to the new societal needs.
