Abstract
According to various embodiments of the invention, a map of injection pin profiles is experimentally determined at various locations spanning an engine operating plane. Injector pin profiles at points within the continuum spanned by the experimentally determined profiles are determined by interpolating between surrounding experimentally determined injector pin profiles. Various methods are used to adjust the interpolation procedure in cases where one injector pin profile has more or fewer points than the other injector pin profile.
