<p><P>PROBLEM TO BE SOLVED: To arrange a heat exchanger for cooling an operation material of an internal combustion engine while saving space in a cooling circuit of the internal combustion engine, and to operate it efficiently as much as possible. <P>SOLUTION: The cooling circuit of the internal combustion engine includes the internal combustion engine 2 with a cylinder block 4 and at least one cylinder head 3, a cooling water pump 5, a main heat exchanger 6, and the heat exchanger 7 for the operation material of the internal combustion engine. The cooling circuit 1 branches off between a branch point A and a connection point B downstream of the cooling water pump 5. At least one cylinder head 3 is incorporated in a cylinder head branch circuit 8. The cylinder block 4 is incorporated in a cylinder block branch circuit 9. The heat exchanger 7 for the operation material is arranged downstream of at least one cylinder head 3 in the cylinder head branch circuit 8. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
