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 11):
A method, comprising:\n flowing gases from a first set of exhaust valves to a compressor disposed in an intake passage and flowing exhaust gas from a second set of exhaust valves to a turbine disposed in an exhaust passage and not to the intake passage, where each cylinder of a plurality of engine cylinders includes one valve of the first set of exhaust valves and one valve of the second set of exhaust valves; determining a dilution rate of the gases flowing from the first set of exhaust valves to the compressor based on a temperature of each of: the gases flowing from the first set of exhaust valves to the compressor, before the gases enter the intake passage, intake air flowing in the intake passage, upstream of where the gases from the first set of exhaust valves enter the intake passage, and combined gases flowing through the intake passage, downstream of where the gases from the first set of exhaust valves enter the intake passage; and adjusting one or more of fuel injection to the plurality of engine cylinders and spark timing based on the determined dilution rate.
