ABSTRACT:
In order to prevent dry spots being produced by abnormally large amounts of coolant suddenly being discharged in the form of a boiling froth or foam, from the coolant jacket of an engine wherein the coolant is introduced in a liquid form, boiled and discharged in gaseous form, the cylinder head is arranged with a coolant jacket structure wherein gaseous coolant and/or coolant foam is accumulated in a relatively large space and subsequently discharged upwardly through a plurality of ports and thereafter undergo multiple deflections and changes of direction in a manifold which includes an "expansion" chamber. This induces any liquid coolant to separate from the gaseous coolant and to flow back toward the structure defining the combustion chamber and coolant jacket formed in the cylinder head. Further, cool liquid coolant (from the heat exchanger) is introduced into the cylinder head coolant jacket in a zone of high heat flux.
