Piston & Connecting Rod Assembly Line Drawing - IPC Engine Figure 61c

This document is an untitled, unlabeled line drawing (schematic-style illustration) of an engine piston and connecting rod assembly. The piston is drawn from an angle looking across the crown toward the connecting rod, revealing multiple ring grooves and what appear to be slots or drilled holes arranged in bands around the piston body, possibly for oil drainage or an unconventional piston design. The connecting rod is shown attached at the small end via the wrist pin boss, with its big end and cap bolts visible at the right of the frame. There is no text of any kind — no dimensions, part numbers, torque values, legends, or captions — so a reader can learn only the general geometry and configuration of the depicted piston/rod assembly. Based on the filename (IPCengineFig61c.jpg) and companion files in the same album (e.g., IPCengine2011figXX images and 'hyperexpansion' engine patent pages), this appears to be one figure from a series of illustrations related to an experimental or patent-described internal-combustion engine concept, rather than a standard Ford service document. The drawing does not state any vehicle applicability, year, make, or model, so its relevance to the uploader's claimed 1969 Ford Fairlane cannot be confirmed or denied from the image itself.
