Hybrid Crank Drive

You have a pretty interesting post. First off your patents are expired so in essence you have nothing. You couldn't protect any idea from the 1980s. If you understand how engines and "clearances" work you can see some BIG problems with the crank design. Focus on 22 and 23. That area would fail under just a slight load. I could go on and on about why it wont work but I'm sure you'll see others jump on that.

Interesting post, thanks for sharing it.

yes thanks for the comment, the patent that i posted, this design was built back in the 80's by my father, a running motor, and your correct, we had power loss due to the added so called "Bell Cranks"(friction gain outwayed the power gain), the failure here led him into a different direction with his current design which i was asking about!thanks again!

Okay I don't understand your question then. Are you saying the links you posted aren't for the engine you want to take to the next level?

correct, they are past failures, a new design is sitting on the bench, ready for R & D work!

Without knowing what you're actually working on (top secret) it's actually hard to say. Building an entire working engine isn't easy. The main thing here is to ask 2 questions. Why, what application? As to the "why", your engine has to in some way be better than what's available. It has to make more power, have better mileage, weigh less, etc. Otherwise all you're doing is making the same power but just in a different way/design. No one will buy that. As to "application", you mentioned auto companies. Are you saying this is specifically designed for the auto world? If it is and some auto company was interested it would take years of testing on their part to prove out the design. You'd basically be asking them to do several millions of dollars of research to improve and prove your design. That isn't too likely.

If you wanted to approach most investors you have to have a working model. You might be envisioning a V-8. I'd suggest you make a single cylinder (2 cylinder if you have some sort of opposing design) that can be shown to investors. Sketches and drawings wont usually get much funding. In your pitch I'd leave the 30 years and failed patents out of your story. Just focus on what you have today.

I'd also be scanning the patent registry on a regular basis to make sure what you have is unique. I personally applied for a patent (auto industry related) on a safety device that was uncovered when I did my patent search. In the time my attorney wrote up and submitted my idea someone else was awarded a patent that had a claim that covered a key element of mine. I got stopped out right there.

I'm not trying to discourage you but again I stress, you have to have something "better", not just different. And you have to be able to prove it to get the attention of investors.

I looked at the design you scraped. Assuming the newer design is basically the same I assume you're looking to make more low end torque. It didn't looking like a high rev design. Am I right?

yes, your analogy is pretty spot on! We have been through the stages of actually building an entire motor block from sand casting, right through to machining and assembly of a working model.And Yes the new design is suited to a low rev diesel motor. As my father once discussed years ago, the future in the motor industry will be with diesel, as you can see most european economical priced vehicles are nowadays offered as diesels(better thermodynamic efficiency).thanks again, enjoy the aspects of discussing ideas to progress the ancient combustion engine, into a new efficient/economical form!

Bell-cranks are not a new invention, you will find many different types on many different types of steam engines from the 1800s and early 1900s!

Spencer.

And by disclosing it here, you may have legally voided any possibility of patent protection anyway.

Not exactly. If he had indeed disclosed anything which is patentable, he has thereby opened up his 'bar date'; and, he now has 1 year to apply for that patent.

"What would be the best avenue to persue with this technology"

First, document and date everything, before disclosing anything to anybody.

Make anyone you show the technology to sign a non-disclosure agreement. Finding an honest partner can be tricky.

Then, you'll have to decide how you can best protect your intellectual property. It will be a question of money, unless you have vast resources already at hand.

I went through this with active noise cancellation 20 years ago. There are plenty of companies willing to talk to you, if you are not a crackpot. It just takes time.

thanks for the advise,I hope to one day post the finished design with positive results!On a side note, i believe in the past 100 years most enhancements/powergains have occured mainly from the block upwards(eg, fuel injection,turbo, multi valves etc) whereas the bottom end has essentially remained primative. This is where in my opinion gains of great magnutude can be produced, if the correct mechanism is designed!

I don't know that it is possible to have "great gains" in any mechanical system. There are so many trade-offs with efficiency, mass, materials, lubrication, ease of manufacture, etc. that makes incremental increases the usual course of events. I can tell you now that having a working model in hand that has measureable benefits over existing designs is the fastest way to interesting other parties.
