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 feedforward model that includes determining a pressure differential across a region in an intake passage, mapped engine parameters such as gas temperature, and exhaust valve timing. Engine operations such as spark advance and fuel injection may be adjusted according to the modeled rate to reduce engine knock and improve combustion efficiency.

Claim (Index 14):
The method of  claim 13 , wherein the determined dilution rate is further based on a temperature of the gases flowing from the first set of exhaust valves to the compressor, where the temperature is a mapped temperature that is based on engine speed, engine load, a temperature correction that is based on a maximum and minimum EGR temperature according to a range of EGR flow during engine operation.
