Abstract

A cylinder head is disclosed herein to allow for temperature control of exhaust gases exiting from an associated exhaust manifold. The cylinder head includes a combustion section that defines a plurality of combustion chambers and an exhaust manifold coupled to the combustion section. The combustion section fluidly couples to exhaust inlets defined by the exhaust manifold. The exhaust manifold includes at least one exhaust passageway in fluid communication with the exhaust inlets and in fluid communication with an exhaust outlet to receive combustion gases from the combustion section and output the same via the exhaust outlet. The exhaust manifold further includes at least one coolant passageway that at least partially surrounds the at least one exhaust passageway to pass coolant therethrough in order to draw and reject heat from exhaust gases.
