Özet:

 



The internal combustion engine
is used daily for transportation and energy production beside their low thermal
efficiency level. Most of the thermal energy in such engines is wasted.
Therefore, energy recovery in diesel engines are crucial in order to enhance
their performance and the environmental penalty. The present paper discusses the
energy recovery potential of internal combustion engine cooling system by using
organic Rankine cycle (ORC). An  heavy-duty
diesel engine that has a maximum brake power rating of about 345 kW is selected
for the energy recovery potential investigation. Around eighty different type
organic fluid is considered as the working fluid. Operability margin of each
fluid as a function of  cooling system
pressure is identified based on fix evaporator and condensation conditions. The
mass flow rates required for each ORC system are computed together with the
cycle thermal efficiencies for each cycle conditions. The results show that
such ORC system is capable of recovering up to 13.6% of the wasted heat which
corresponds to a power recovery of about 24 kW and enhances the diesel engine
brake efficiency by 2.4%.
