Energy Management for RCCI Engines with Electrically-Assisted Turbocharging

In this paper, Reactivity Controlled Compression Ignition (RCCI) with an electrically-assisted turbocharger (E-turbo) is investigated. This a promising concept for future green transport, since it can realize very high thermal efficiencies wide range of renewable fuels. The combination RCCI E-turbo requires new approach to manage the energy flows engine due constraints on storage electrical energy. shows most potential increase engine's efficiency by improved tracking performance desired intake conditions. To exploit full during transients, dynamic decoupling feedback controller designed. A supervisory based Pontryagin's Minimum Principle composed maximize brake while battery remains charge sustaining. determines setpoints and ensures therefore optimal operation transients. For simulated, real-world transient-cycle, fuel savings 0.64 [%] are realized developed control, remaining
