PISTON WITH COMPLEX SHAPED COMBUSTION BOWL AND COOLING GALLERY AND METHOD OF CONSTRUCTION THEREOF |
摘要 |
A piston and method of construction thereof is provided. The piston has a lower member with diametrically opposite skirt portions and axially aligned pin bores and an upper member joined to the lower member. The upper member has a substantially planar upper combustion surface and a combustion bowl depending from the upper combustion surface. An undercrown surface is formed directly opposite the combustion bowl and a combustion bowl rim transitions the combustion bowl with the upper combustion surface. At least one of the combustion bowl, the undercrown surface and the upper combustion surface has a machined surface and an “as forged” surface. |
