Engine Designers

I do like the idea, but the belt's path is what I'm afraid of...

Twists and turns will - surely - reduce its lifetime, increasing the cost later.

I can suggest other ways to avoid such twists: mechanical ways, but that will get us back to the start where we want to reduce everything while retaining functionality.

I had some discussions about twist of belt and no one actually gave me reason why twisting belt is bad other than because it is not designed to be used this way. Maybe someone will at some point. What you look at is a start point not a finished product. I think about replacing belt with use of closed hydraulic loop. I only try to find an answer if it has potential to compete with standard engine. Thanks for you comment

Check this discussion...

This would be new way of driving cam ring. Balls dipped in oil run through channel.

is a good design. but if you could use steel belt and the belt itself have some angle of twist.

How can you make a twisted steel belt?

maybe using concept of conveyor belt.

That's impossible...

In the conveyor, the belt doesn't twist, it turns.

On the other hand, this timing belt doesn't turn, it twists.

Check these GIFs to know the difference.

Turning:

Twisting:

My opinion is the design wise, avoid use long belting.

I was just proving that what you said here cannot be done...

Nice concept ...

A rotating cam to control the valves of a cylinder of internal combustion engines ...

This type of rotary mechanism to control the distribution of gases in the cylinder of an internal combustion engine is not new ... some solutions choose to replace the camshaft, but also the traditional souppapes.

in this area, I believe that the solutions invented and produced by engineer Pattakon are perfectly optimized. The exellent work of this engineer should inspire many others.

Looks good

The belt and rotating cam ring are overly complicated and destined to fail. The rotating valve openings have a major problem. How does it seal the combustion chamber. With computer and electronics technology the way it is today why not just use solenoids to open and close the valves? I know same problem as the belt and cam ring. Destined to failure. Reinventing the wheel is hard to do. Need to simplify to make it better. Factors to consider, friction, wear, strength, reliability, weight, and seal. Good luck.

The belt solution has been done before, in the seventies a twostroke engine for outboard and roadracing

I'm glad to learn the belt idea would work. Thanks for sharing

Btw. I also learned that this kind of twisted belt idea is used in industrial robots
