Smaller heads for PUG V6?

by David Zatz on

A recently granted patent (applied for back in 2011 by Chrysler’s Richard H. Sands and Alan G. Falkowski) can cut Chrysler’s costs and reduce the size of their engines, helping the company to either fit larger engines into their cars, or to lower their hoods.

The patent applies to in-line and V-engines alike, which means it could be used for the upcoming Hurricane turbocharged four-cylinder; but the drawings and a specific size example are taken from a V6 engine, presumably the PUG (Pentastar Upgrade).

According to the patent description, the new setup would integrate valve controls into the head, rather than having them sit on the outside with a separate cover; passages inside the head would provide access to the valves. This would save space and reduce cost. Thanks, Steven St. Laurent, Marine engineer.
