Applicability of Water Injection in Combination with an eFuel

This chapter investigates the possible coexistence and combined application of water injection and the adoption of eFuels in a GDI engine. The goal is to assess the advantages or disadvantages that the adoption of the eFuel POSYN in combination with water injection strategies can bring, with respect to the same strategies applied in combination with a commercial gasoline E10. Several water injection configurations have been tested for both fuels, including DWI and IWI.
