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 4):
The method of  claim 1 , wherein determining the dilution rate of gas recirculated from the first set of exhaust valves to the intake passage includes determining the dilution rate of gas recirculated from the first set of exhaust valves to the intake passage, upstream of a turbocharger compressor based on each of a first temperature of intake air in the intake passage, upstream of the turbocharger compressor, a second temperature of recirculated gases in the recirculation passage, upstream of where the recirculation passage couples to the intake passage, and a third temperature of combined air and recirculated gasses in the intake passage, downstream of the turbocharger compressor.
