ABSTRACT:
An evaporable foam pattern for casting a metal water-cooled exhaust manifold for an internal combustion engine. The assembled pattern is formed of an evaporable foam polymeric material, such as polystyrene, and includes an inner exhaust conduit composed of a generally upright body portion and a generally curved elbow portion. The body portion is provided with a plurality of inlet ports connected to the exhaust passages of a bank of cylinders, while the elbow portion defines a downwardly facing outlet. The pattern also includes an outer water jacket which is spaced from the exhaust conduit to provide a water passage therebetween. Both the exhaust conduit and the outer jacket are composed of two longitudinally split halves or sections having abutting edges, and the abutting edges are joined together by an adhesive. Spacing ribs interconnect the inner surface of the jacket and the outer surface of the exhaust conduit to space the sections apart. The inlet ports of the exhaust conduit section are located only in one of the exhaust conduit pattern sections.
