An Application Study of Evaporative Cooling to Heavy Duty Diesel Engines 870023
Evaporative cooling was applied to a heavy duty diesel engine to investigate the feasibility of this cooling method.
Engine test results showed the following benefits of this cooling method: Reduction of the size of theradiator and cooling fan is feasible. The maximum temperature of the combustion chamber wall did not increase, though the coolant temperature rose by 20°C. The fuel consumption could be reduced especially at partial load. Engine warm-up performance was significantly improved.
An oil cooler rig test was also conducted to investigate the heat transfer characteristics of the oil cooler with evaporative cooling.
