Abstract
A closed passage system surrounding an engine cylinder for cooling purposes. Fins extend longitudinally along the various passage sections to promote heat transfer into the air flowing through the passage. Fin density varies according to the heat load. Near the upper end of the combustion chamber, a large fin density is used; near the lower end of the chamber a lesser fin density is employed. An effort is made to continuously guide the coolant air for efficient heat removal action.
