An engine component includes stratified metal layers. The stratified metal layers form walls of a cylinder head having internal cavities defining a cooling jacket configured to direct coolant within and through the walls. The stratified metal layers also form a lattice disposed within and spanning between opposing surfaces of the cooling jacket configured to promote heat transfer between the stratified metal layers and coolant.

Cylinder head of an internal combustion engine

An engine cooling system is provided with an internal combustion engine defining a head cooling jacket and a block cooling jacket in a split flow configuration. A first thermostat is positioned at an outlet of the block cooling jacket and configured to control coolant flow therethrough. A second thermostat is positioned to receive coolant flow from the first thermostat and the head cooling jacket. The first and second thermostats are in a thermostat assembly within a housing. In response to coolant temperature being below a first threshold, a first and a second thermostat downstream of the engine in a thermostat assembly are closed such that coolant flows through a head jacket and the thermostat assembly to a pump, and such that coolant in the head jacket entrains a trickle flow of coolant from a block jacket through an interbore cooling passage, thereby cooling an interbore region.

Cooling system for an internal combustion engine

An engine cylinder block forms a cooling jacket adjacent to a cylinder and that intersects a deck face adapted to mate with a cylinder head. The cooling jacket has an inlet passage intersecting a mounting face adapted to mate with a coolant pump housing. The block forms a vent passage extending from the cooling jacket to the mounting face. The pump housing forms a volute adapted to receive an impeller. The housing forms a discharge passage that fluidly connects to the inlet passage of the block. The pump housing also forms a vent passage the fluidly connects with the vent passage of the block. The vent passages of the block and pump housing are positioned between the deck face of the block and the inlet and discharge passages when the pump housing is connected to the engine block.
