Advanced concepts and alternative fuels

This research line focuses on studying combustion processes in SI engines, addressing the relevant physics and chemistry under real operating conditions. It explores strategies to enhance thermal efficiency and reduce pollutant emissions by combinig advanced experimental and numerical techniques. Alternative fuels -such as hydrogen and bio/exfuels- are investigated for integration into next-generation engines.
