| Abstract: | Skirt profile is all along a trouble in piston design.Curve fitting based
on a successful designed piston or an ideal skirt profile after engine running in is still
an effective and useful method for acquiring the design guideline and design parameters.
This paper provides a fitting method for a polynomial of degree n with multifunctions
and restrained conjoint points. |
