Abstract
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.

An engine component comprising:
- stratified metal layers forming
- walls of a cylinder head having internal cavities defining a cooling jacket configured to direct coolant within and through the walls, and
- 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.
An engine component comprising:
- a cylinder head including walls of stratified metal layers having internal cavities defining a cooling jacket configured to direct coolant within and through the walls, and including a pillar of stratified metal layers disposed within and spanning between surfaces of the cooling jacket such that a body of the pillar is spaced away from the surfaces to disturb flow of the coolant through the cooling jacket.
A cylinder head comprising:
- cylinder head walls formed of stratified metal layers having internal cavities defining a cooling jacket configured to direct coolant within and through the walls;
- and
- a cupped partition formed of the stratified metal layers disposed within and spanning between surfaces of the cooling jacket such that a body of the cupped partition is spaced away from the surfaces to redirect flow of the coolant within the cooling jacket.
