Powertrains

Task: To develop and improve low CO2 powertrains using thermal engines, in compliance with changes in international regulations (on emissions, cycles, …)

1 - Powertrain architecture (engine, drive train, auxiliaries)

• Downsizing , Down-speeding, Air Loop, Variable Distribution, variable compression ratio
• Hybridization, range extenders
• Intelligent transmissions for hybrid engines, engine-gearbox connections (2 and 3 cylinder engines)
• Auxiliaries: alternators, pumps, compressors, etc…
• Friction and lubrication •Reduction of general spending on energy

2 - Combustion, after-treatment and fuels

• Combustion systems (two-stroke , homogeneous combustion….)
• Injection Systems
• After-treatment systems(FAP, SCR, NOx-Trap…)
• Alternative fuels (CNG, biofuels, H2…)

3 - Management and recovery of thermal energy

• Energy recovery: thermoelectricity, turbo generator, Rankine cycle, Stirling engine…
• Thermal auxiliaries: Heating pump, storage systems, exchangers…
• Thermo management, thermal distribution: Engine / After-treatment / Passenger Compartment

4 - Powertrain Digital Engineering

• Understanding and Modelling physical and chemical phenomena (0D, 1D, 3D…)
• Powertrain design tools and methodologies (components…)
• Definition and design of test and measuring methods and innovatory methodologies
• Experimental Approvals
• Engine tuning and checking
• Coupling of models with measurements (HIL)
