Abstract
A rotary internal combustion engine having an insert opening defined in a hot area of one of the walls of the stator body and in communication with its internal cavity, at least one groove defined within the opening around a perimeter thereof, at least one coolant inlet channel defined therein in communication with each groove, and at least one coolant outlet channel defined therein in communication with each groove. A cooling jacket lines the insert opening, the cooling jacket cooperating with each groove to define a cooling gallery around the insert opening. An insert is sealingly received in the cooling jacket, the insert being made of a material having a greater heat resistance than that of the wall.
