Abstract
A cooling system for a reciprocating multicylinder internal combustion engine includes discharge passages for conducting coolant from the cylinder block to specific regions of the cylinder head so as to increase the localized heat transfer coefficient between coolant and the cylinder head. Flow through the cylinder head is separated into an intake side flow and a central and exhaust side flow so as to promote better heat transfer and to allow the engine to be operated with a higher compression ratio and greater spark advance.
