High specific power, a wide speed range with maximum torque and good transient behavior — these are the main characteristics that distinguish modern downsized engines.
In the future, to further reduce engine displacement more sophisticated solutions than single stage turbocharging need to be analyzed.
The advantages of an increased downsizing level are reduced at high engine loads or for vehicles with higher drag resistance, due to earlier and stronger fuel enrichment. A reduction of fuel enrichment is required to achieve further fuel savings in customer-relevant operating conditions.
This work analyzes and compares charging concepts to increase the downsizing level as well as technologies to reduce the fuel enrichment.
