Method of and system for heat recovery for an internal combustion engine

Abstract

Heat recovery for internal combustion engine, includes introducing a first fluid into heat exchanging element, and withdrawing the heated first fluid from the heat exchanger elements; and supplying at least one second fluid which is used during the operation of the internal combustion engine and is heated, so as to flow outside and in contact with the heat exchanging elements to transfer heat through walls of the heat exchanging element from the second fluid to said first fluid.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:  
     
         1 . A method of heat recovery for internal combustion engine, comprising the steps of introducing a first fluid into said heat exchanging elements of a heat exchanger for heating the first fluid, and withdrawing the heated first fluid from the heat exchanger elements; and supplying at least one second fluid which is used during the operation of the internal combustion engine and is heated, so as to flow outside and in contact with said heat exchanging elements to transfer heat through walls of said heat exchanging element to from said second fluid said first fluid.  
     
     
         2 . A method as defined in  claim 1 , wherein said supplying the second fluid includes supplying a coolant used during the operation of the internal combustion engine.  
     
     
         3 . A method as defined in  claim 1 , wherein said supplying the second fluid includes supplying a lubricant used during the operation of the internal combustion engine.  
     
     
         4 . A method as defined in  claim 1 , wherein said supplying the second fluid includes supplying an exhaust produced during the operation of the internal combustion engine.  
     
     
         5 . A method as defined in  claim 1 , wherein said supplying the second fluid includes supplying at least two second fluids selected from the group consisting of a coolant, a lubricant and an exhaust of the internal combustion engine.  
     
     
         6 . A method as defined in claim  1 ; and further comprising bringing the second fluid into a contact with a catalytic material applied on an outer surface of said heat exchanging elements to cause a catalytic process and to release heat.  
     
     
         7 . A method as defined in claim  1 ; and further comprising using heat received by the first fluid for creating a heat.  
     
     
         8 . A method as defined in claim  1 ; and further comprising using heat received by the first fluid for creating a work energy.  
     
     
         9 . A method as defined in claim  1 ; and further comprising withdrawing crank case fumes from the internal combustion engine and supplying them into an engine exhaust pipe.  
     
     
         10 . A system for heat recovery for an internal combustion engine, comprising a heat exchanger including a plurality of heat exchanging elements; means for introducing a fluid into said heat exchanging element for heating the first fluid, and withdrawing the first heated fluid from the heat exchanger elements; and supplying at least one second fluid which is used during the operation of the internal combustion engine and is heated, so as to flow outside and in contact with said heat exchanging elements to transfer heat through walls of said heat exchanging element from said second fluid to said first fluid.  
     
     
         11 . A system as defined in  claim 10 , wherein said means for supplying the second fluid includes means for supplying a coolant used during the operation of the internal combustion engine.  
     
     
         12 . A system as defined in  claim 10 , wherein said means for supplying the second fluid includes means for supplying a lubricant used during the operation of the internal combustion engine.  
     
     
         13 . A system as defined in  claim 10 , wherein said means for supplying the second fluid includes means for supplying an exhaust produced during the operation of the internal combustion engine.  
     
     
         14 . A system as defined in  claim 10 , wherein said means for supplying the second fluid includes means for supplying at least two second fluids selected from the group consisting of a coolant, a lubricant and an exhaust of the internal combustion engine.  
     
     
         15 . A system as defined in claim  10 ; and further comprising a catalytic material applied on an outer surface of said heat exchanging elements such that the second fluid is brought in contact with the catalytic material to cause a catalytic process and to release heat.  
     
     
         16 . A system as defined in claim  10 ; and further comprising means for using heat received by the first fluid for creating a heat.  
     
     
         17 . A system as defined in claim  10 ; and further comprising means for using heat received by the first fluid for creating a work energy.  
     
     
         18 . A method as defined in claim  10 ; and further comprising means for withdrawing crankcase fumes from the internal combustion engine and supplying them into an engine exhaust pipe.
