Abstract
This disclosure provides a cylinder head having a structure allowing for more uniform lateral coolant flow, and an internal combustion engine including such a cylinder head. The cylinder head includes a lower water jacket cavity, an upper water jacket cavity in fluid communication with the lower water jacket cavity through plural orifices formed in cylinder head material between the lower and upper jacket cavities, and a coolant outlet passage extending from the upper water jacket cavity to a lateral side of the cylinder head. A rail cavity is provided in the cylinder head, extends in a longitudinal direction of the cylinder head, and is in fluid communication with the coolant outlet passage. A lateral passage is provided in the cylinder head upstream from the coolant outlet passage with a portion of the rail cavity therebetween. The lateral passage fluidly connects the upper water jacket cavity to the rail cavity to allow lateral flow of coolant in areas of the cylinder head upstream from the coolant outlet passage.
