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 8):
The method of  claim 1 , wherein the gas recirculated from the first set of exhaust valves includes a portion of each of burnt combustion gases, fresh blowthrough air, and unburnt fuel.
