Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, while both a first exhaust valve and second exhaust valve of a cylinder are open, intake air may be routed through a flow passage coupled between the intake passage and the first exhaust manifold, the first exhaust manifold coupled to the first exhaust valve. The intake air may be further routed through the first exhaust valve, into the cylinder, and out of the second exhaust valve to the second exhaust manifold coupled to the exhaust passage including a turbine.

Abstract: Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, exhaust from a first set of exhaust valves coupled to the first exhaust manifold may be selectively routed to the intake passage via each of a first EGR passage coupled to the intake passage upstream of a compressor driven by a turbine and a second EGR passage coupled downstream of an outlet of the compressor. A decision of whether to route exhaust gas to the intake passage via the first EGR passage, second EGR passage, or both passages may be based on engine operating conditions.
