Abstract
A reduction of hot spots in the combustion chambers and the simultaneous elevation of bore temperature in an internal combustion engine are achieved by a boiling liquid cooling process in which a high molecular weight, high saturation temperature organic coolant is supplied to the coolant jacket of the engine head entirely in the liquid state, thereby greatly reducing the ratio of vapor to liquid in the head jacket for more effective heat transfer from the head to the coolant.
