Heat Balance and Cooling of Heavy Duty Engines 630331

We pay for all fuel supplied to an engine, but in most cases get back only 33% of investment in the form of brake horsepower. The remaining 67% appears as heat in the engine jacket water, heat in the exhaust gas, and radiated heat.
This paper deals with the energies coming out of the engine; where they come from, their intensities, and their disposal or recovery. Graphs show trends of output energies as influenced by engine load, speed, and atmospheric conditions.
Properly designed cooling systems and their installations are covered in the text and shown in illustrations.
