Abstract:
Methods and systems are provided for determining a dilution of recirculated gases, including blowthrough air, combusted exhaust gas, and fuel vapor, in a split exhaust engine. In one example, the dilution rate may be calculated using a steady state model based on temperature measurements from an intake region of the engine. The steady state model may be further used in combination with a feedforward model adapted to estimate engine dilution during engine transients as a correction factor.

Claim (Index 15):
The method of  claim 13 , wherein adjusting one or more of fuel injection to the plurality of engine cylinders and spark timing based on the determined dilution rate includes actuating one or more fuel injectors to increase an amount of fuel injected into the plurality of engine cylinders in response to the determined dilution rate decreasing.
