Abstract
Systems and methods are provided for an engine system having a split exhaust system. In one example, a system may include an engine having a plurality of cylinders, each of the plurality of cylinders including first and second exhaust ports, the first and second exhaust ports arranged in a non-alternating pattern across the plurality of cylinders and along a cylinder head, a blowdown exhaust manifold coupled to the first exhaust ports and an exhaust passage, and a scavenge exhaust manifold coupled to the second exhaust ports and an intake passage of the engine. In this way, the first and second exhaust ports may be arranged to enhance turbocharger performance characteristics.
