In view of stricter emission limits and rising demands on driving performance and CO2 reduction at the same time, FEV has investigated solutions to the conflict between increasing specific power and switching to stoichiometric combustion throughout the engine map. Based on a V6 3.0-l bi-turbo engine this paper shows how the engine can be laid out to 200 kW/l and stoichiometric operation in an electrified powertrain. The engine features a central fuel injection, single-stage turbochargers with variable turbine geometry and port water injection. RON98 fuel was used during engine testing.

Combustion Process

Water injection represents the key technology to achieve high specific engine power with lambda = 1. The reduction of the mixture temperature associated with the high evaporation enthalpy of water at the end of compression allows for a significant increase of the efficiency of the high pressure cycle [1, 2]. Therefore, fuel enrichment to reduce the exhaust gas temperature is not...
