Abstract

An engine having a cylinder head including an exhaust manifold at least partially integrated therein, the exhaust manifold including an inner separating wall fluidly dividing two merged exhaust lines, each merged exhaust line in fluidic communication with a different pair of adjacent cylinders, and an outer separating wall fluidly dividing a first exhaust line in direct fluidic communication with a first cylinder and a second exhaust line in direct communication with a second cylinder, a lateral width of the inner separating wall greater than the outer separating wall, the lateral axis perpendicular to a longitudinal axis traversing centerlines of each cylinder.
