The focus of this area is the efficient use of energy from fossil as well as from renewable fuels (e.g. bio and e-fuels) by means of innovative Internal Combustion Engine (ICE) concepts capable to minimize their carbon dioxide and pollutants emissions. Automotive, marine, off-road vehicles and stationary applications are covered.
Both experimental investigations, performed at DENERG Advanced ICEs lab, and numerical investigations, by means of CFD numerical simulations (1D and 3D) are carried out in the framework of several collaborative research projects with major OEMs and powertrain engineering Companies (such as Stellantis, Ferrari, Iveco Group, CNHi, Punch, ENI, Wartsila, Yanmar, AVL and FEV). Close collaborations with CFD software companies such as Gamma Technologies and Convergent Science, are also currently ongoing to support the development of new modelling techniques to support the development of the future generations of ICEs.
Examples of recent and on-going research activities include:
- Experimental and Numerical optimization of the combustion process in ICEs running with HVO, FAME blends, H2, methanol and ammonia, exploiting innovative injection and combustion strategies and combustion chamber design.
- Optimization of the pollutants abatement performance of advanced aftertreatment systems for automotive as well as for off-road applications.
- Mixture formation and combustion in DI gas engines (including biogas and hydrogen)
- Analysis and optimization of innovative combustion processes such as Turbulent Jet Ignition, HPDI and Dual Fuel.
- Analysis of knock mitigation techniques in SI engines (such as Miller cycle, Variable Compression Ratio, water injection and cooled EGR).
