Owen,

THANKS for the picture. What a clever design. If I'm looking at it correctly, it had a "pent roof" piston top and head. Unfortunately the pic doesn't show the piston at TDC, but it seems like one side of the piston provided the "squish" area, and the side nearest the valve fit up close to the valve seat, and the machined "wedge" in the head completed the "wedge." Part of the combustion chamber was thus alongside the cylinder, not directly above it, but as close to the source of the air/fuel mixture could get.

Am I reading that right?


I still wonder if I'm reading this quote right, but I think PackardV12Fan wrote:

Keep in mind that after 1930's, Packard had pretty well abandoned the actual manufacture of autombiles, being essentially an assembler of parts designed and produced by others.


Well, this is going a little too far. As Kev pointed out, Packard was by then building its own bodies, had the ONLY automatic transmission built by any independent auto manufacturer--even the "big three"--had a brand new Packard designed and built V8, and one thing Kev forgot, introduced a proprietary 4-wheel torsion bar suspension system.

Maybe the build quality wasn't the best, and they had some teething problems, they were no joke, especially to the automotive press, which especially gave credit to the Torsion-Level suspension. That alone, had it survived the corporate stodginess of the "big three" would have made a huge difference in suspensions to this day, I think.
