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 19):
The system of  claim 16 , further comprising a first temperature sensor positioned in the EGR passage, a second temperature sensor positioned in the intake passage, upstream of where the EGR passage couples to the intake passage, and a third temperature sensor positioned in the intake passage, downstream of the turbocharger compressor and wherein the first temperature, second temperature, and third temperature are measured temperatures determined from outputs of each of the first temperature sensor, second temperature sensor, and third temperature sensor, respectively.
