  7. Abstract:
  8. The Engine of a vehicle is an energy conversion system, where specific chemical energy is converted in to heat in a combustion chamber. In order to reduce thermal tension in the cylandr, part of heat is removed with the help of circulating water and it is dissipated in the radiator. As a result, part of input energy is wasted in to the atmosphere through cooling system in each cycle of engine. Heat recovery in the cooling system and preheating combustion air of fuel could enhance energy efficiency and it may contribute to fuel economy. Heat recovery may be realized with the help of heat pipes. Heat pipes may be utilized for heat recovery and preheating fuel or air whichare inlet to the combustion system in an engine. A review of litreture indicates that heat removal and optimal designe of radiator for heat dissipation have been major elements of research in the field and development of models based on CFD has been the main subject. Research activities have been involved with the imporoving heat exchanger (radiator) efficiency empirically.
    The present research work has focouesd on evalution of a heat recovery system based on the application of heatpipes in radiator. Therfore, a conceptual model of energy flow in an engine is developed and energy balances for the whole engine has been prepared. A heat recovery system based on heat pipes has been designed and its specification has been applied in energy balances. Evaluation of energy balances indicates that cooling may be reduced by 1% and fuel consumption may be reduced by 0.6%. Results indicate that energy saving would be possible when aheat recovery system is employed in a vehicle engine
