ABSTRACT:
An evaporable foam pattern for casting a metal engine block for a two-cycle engine having a direct charge system. The pattern includes a block pattern section having a head end and a crankcase end and a plurality of cylinders extend between the ends. A transfer passage is associated with each cylinder and one end of each transfer passage communicates with the crank-case end of the block, while the opposite end of the transfer passage communicates with the cylinder adjacent the head end. The block pattern section is provided with a plurality of openings each of which provides communication between a transfer passage and the exterior and the openings are bordered by a generally planar surface. The pattern also includes a cover pattern section enclosing the openings in the first section. The cover pattern section has a peripheral flange disposed in abutting relation with the planar surface of the block pattern section and the cover pattern section includes a plurality of inwardly facing portions, each of which is received within an opening in the block section and defines the outer wall of a transfer passage. The abutting surfaces are joined together by an adhesive.
