IPC Engine 2011 Fig 21a - 3D Cutaway of Piston, Rod & Cylinder Liner Concept

This document is a computer-generated 3D cutaway (cross-section) illustration of an internal combustion engine cylinder assembly, apparently from an 'IPC engine 2011' figure series (filename indicates Fig. 21a). The rendering shows, in color-coded form, a piston (green) with piston rings, a connecting rod and wrist pin (cyan), a cylinder liner or sleeve (magenta), a lower liner support or spacer (gold/yellow), the surrounding engine block structure (beige/gray), and what appears to be an injector or valve arrangement at the top of the cylinder with a spray or flow pattern indicated by a red dashed outline near the piston crown. The image contains no text, legends, dimensions, torque specifications, or part numbers, so a reader can learn only the general spatial arrangement and construction concept of this engine's piston, rod, liner, and head interface from the visual itself. It is part of a larger album of engine concept figures (including Chatterton GB988378 'hyperexpansion' patent scans and other IPC engine figures), suggesting it documents an unconventional or experimental engine design concept rather than a stock production Ford Fairlane component. No year, make, or model applicability is stated anywhere in the image itself.
