Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Porsche has patented a six-stroke internal combustion engine design. It uses a special crankshaft to create extra compression and power strokes per cycle. https://www.motor1.com/news/734156/porsche-six-str... Details of the patent at: https://patentcenter.uspto.gov/applications/185853...

POST 2Original post

Cool. Only read the article not the tech, but sounds like another way of doing what was done with steam engines (secondary lower compression bit after the main event), and I think it was maybe Ilmor or Judd that had the same idea a few years back with the 3cyl engine that was 2 normal high pressure cylinders and a 3rd larger but lower compression one. Whether it becomes a commercial thing or not, great to see development in this area. Would also love to hear how it sounds, presumably like nothing we’ve heard before?

POST 4Original post

An excellent video. You've got to assume that Porsche has built one or some. It would be great to see it running. I wonder what it sounds like. Managing the firing sequence with two powers of strokes will be interesting. That gear mechanism has to be a problem for wear and maintenance.

This is a source reference. Confirm exact model applicability in the original material.
