I hope you get somewhere with this, ChasChas. It would be good to see an internal combustion engine that takes a real step forward beyond the back and forth pistons.

I am still working on the legal protection so it can be presented properly. I have only shown it under confidential disclosure.

It has a mechanism where the actual movement of the pistions, and cylinders are perfectly balanced circles, but the relative motion between them is linear and conventional.  No, it is not anything like a Le Rhône.  Real sweet!

ChasChas, could you tell us a little about your concept? Is it a rotary engine with the bugs worked out?

True, the concepts haven't been strong enough. Now, when I'm sure I have a strong concept, the interest and money has dried up. I'll keep looking for money though. Maybe this post can find a few with money who still beleive.

If I remember right, Chuck, theat pretty much ended the concept of the rotary engine. As for the inefficiency of the piston engine, I wouldn't think that the non-productive return movement of the piston consumers significant energy.

Yes it does seem like we gave up, ChasChas. That's why I'm wondering whether the troubles were because of a weak concept or a weak execution. And is there an alternative to the rotary engine and the piston engine?

I'm no expert on the Wankel, Rob, so I'll take Mirox's word for it that the apex seal problm was solved long ago. I do remember hearing stories in the old days about Mazdas getting their engines rebuilt every 50,000 miles because of the apex seals. I'm sure Mirox is right, though: That was a long time ago.

Well, the literature says we are still wasting 35% of our gas moving the pistons back and forth (normal driving). True rotary engine research sure seems like a must do to me. Like the long range battery, we gotta have it. And it seems like we gave up.

Yes, in business, there are great rewards for successful competition. It brings out some extraordinary effort. I'm not sure it always brings out the best -- sometimes noncompetitive research brings out the best -- but it does spur effort, and that often produces extraordinary results. The moon landing was the result of competition.

If the rotary engine is not being developed in a substantial manner, by vehicle manufacturers, does that mean the traditional piston engine is plenty efficient enough?
