Charge dilution lowers indicated specific fuel consumption by up to 10%, enhancing thermodynamic efficiency.
The advanced corona ignition system reduces combustion duration and improves fuel consumption by 1% to 2% in stoichiometric conditions.
Steady-state tests replicated common operating conditions, highlighting the benefits of both charge dilution and ignition technology.
The findings suggest potential applications for both technologies in hydrogen fuel contexts.
