A middle deck of a cylinder head, comprising:
- a partition coupled to a side of said middle deck remote from a combustion chamber, wherein said partition has a height and divides an exhaust side of said cylinder head from and intake side of said cylinder head;
- a portion without any partitions on said side of said middle deck, where said portion without any partitions is used to control the flow of engine oil from said exhaust side to said intake side;
- and
- a plurality of radiating protruders formed on the surface of said middle deck, effectively enlarging a heat-exchange area.
A cylinder head, comprising:
- an exhaust side;
- an intake side opposite said exhaust side;
- a middle deck separating a lower portion from an upper portion of said cylinder head, where said middle deck is sloped from said exhaust side to said intake side;
- at least one partition coupled to said middle deck in said upper portion, where said at least one partition at least partially seperates said upper portion between said exhaust side and said intake side;
- and a portion without any partitions between at least two partitions.
A middle deck of a cylinder head, said middle deck separating a lower portion of said cylinder head from an upper portion of said cylinder head, where said middle deck is sloped from said exhaust side to said intake side, where said middle deck defines at least one partition in said upper portion that at least partially separates said upper portion between said exhaust side and said intake side, and where said middle deck further defines radiating protruders in said upper portion on both said exhaust and intake sides, where said radiating protruders on said exhaust side have a different shape to said radiating protruders on said intake side.
