  • Two stroke engine with tiered cylinder cooling
    Patent number: 5080049
    Abstract: A two stroke cycle engine has tiered cooling jackets in the cylinder block with upper and lower jackets separated by a diaphragm wall. Transfer openings in the diaphragm and downward portions of the lower jacket direct coolant flow around exhaust ports and preferentially along the exhaust port side of the engine cylinder openings. A cylinder head gasket controls outflow from the upper jacket to the cylinder head through transfer holes placed preferably on the exhaust side of the upper jacket to provide overall control of flow in the cooling jacket system.
