Abstract:
In a fluid cooled internal combustion engine of the type that includes a combustion chamber, cooling fluid passages having a circular cross section and a cylinder head that defines part of the combustion chamber and includes boundary walls located between the combustion chamber and the cooling fluid passages, a method for repairing damaged portions of the boundary walls located between the combustion chamber and at least one of the cooling fluid passages, which has a circular cross section the method comprising the steps of:cutting away the boundary walls of the cylinder head including the damaged portions until the cutting reaches a depth of one-half the cross section of the cooling fluid passage so that there is a remaining portion of the cooling fluid passage;fixing a half-pipe that has a semicircular cross section that is equal in size to one-half the cross section of the cooling fluid passage to the cylinder head so that an inner surface of each half-pipe may serve to form, together with the remaining portion of the cooling fluid passage, a cooling fluid passage.
