Abstract

An aluminum-based diesel engine piston and a method of making the piston. The method involves casting the piston with complex geometries, including undercut or reentrant features. The casting uses an aggregate disposable mold that can be removed from the as-cast part. In one form, the complex geometry includes an undercut combustion bowl formed in the piston dome, while in another, it may include an internal cooling passage. The undercut bowl and internal passages may be produced using the aggregate disposable mold.
