A cylinder head for use with an internal combustion engine, the cylinder head including a body having a fire deck and defining a water jacket in fluid communication with a cooling system, a first runner defined by the body and open to the fire deck to at least partially form a first valve seat, a second runner defined by the body and open to the fire deck to at least partially form a second valve seat, and a channel defined by the in fluid communication with the water jacket and positioned between the first runner and the second runner. The channel, in turn, includes a first inlet through which a first flow enters the channel, a second inlet through which a second flow enters the channel, and where the first inlet and the second inlet are oriented such that the first flow and the second flow interact with one another to create a turbulent region within the channel.

Cylinder head with improved valve bridge cooling

A cylinder head for use with an internal combustion engine, the cylinder head including a body having a fire deck and defining a water jacket in fluid communication with a cooling system. The cylinder head also includes a first runner defined by the body and open to the fire deck to at least partially form a first valve seat, a second runner defined by the body and open to the fire deck to at least partially form a second valve seat, and a channel defined by the body, where the cooling channel is in fluid communication with the water jacket and positioned between the first runner and the second runner, and where the cooling channel includes a flow diverter configured to produce a turbulent region proximate the fire deck.

A cooling jacket is formed at least in part within the cylinder head mounted on an engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder. The cooling jacket includes a first passageway, a second passageway and a turbulence chamber. The first passageway extends from a first flow passage and intersects the turbulence chamber at a first angular position, and the second passageway extends from a second flow passage and intersects the turbulence chamber at a second angular position different from the first angular position. A swirling action is imparted to fluid media passing through the turbulence chamber.
