Abstract
A cooling water system for a rotary internal combustion engine includes initial direct water cooling for the outer surface of the exhaust manifold with the cooling water directed therefrom to serially interconnected cooling water passages in the various housing elements comprising the engine block. The cooling water passage in each housing element is circumferentially disposed along the peripheral portion of the housing which is directly adjacent the high temperature exhaust and combustion areas of the engine rotor chamber. The cooling system thus supplies water directly to the portions of the engine subject to the highest operating temperatures. The system also includes protection against the formation of hot air or steam pockets and the cooling system is readily adaptable to both single and twin rotor engines.
