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 14):
The method of  claim 13 , wherein flowing gases from the first set of exhaust valves to the compressor includes flowing a combination of combusted exhaust gases, fresh blow through air, and unburnt fuel from the first set of exhaust valves to the intake passage, upstream of the compressor, via an exhaust gas recirculation (EGR) passage including an EGR valve and wherein the second determined dilution rate is further based on a differential pressure across the EGR valve and the flow constriction.
