Combustion

Hi, I'm a 20 year old car enthusiast from Greece.

Sometimes in my spare time I like to try and design new engines, usually when I'm just about to sleep and get inspiration, and then spend the next 3 hours trying to get it to work and finally giving up and arriving late for work :). Anyway, my goal is usually to create an engine that can utilise a turbo, so bye bye 2 strokes and mainly just to see if a different design can be used. Also, if the active part (eg piston) can produce useful work more than once every 720 degrees of the crank.

I think I have something here that I'd like your input on. If it doesn't, it's just another paper in the trash can ;). It's just a concept and won't work as it is, but what results is an engine that can compress the gasoline/air every 360 degrees rather than 720.

It uses a flywheel/crank combo which I call the flank. The piston is pulled by the crank to compress and at combustion both the piston and the flank are pushed, meaning the flank turns and the piston is pushed up causing it to turn/pull the flank through the connecting rod.

What do you think?

I've made so many designs, but all of them are flawed in some way or another. One idea was to have a spherical piston with a hole in the middle that spins on an axis so that it can go in a round housing and at compression/combustion, the hole is not exposed and during gas insertion/exhaust removal, the hole faces forward so that the gas can pass through.

Does anyone else have any radical ideas for engine design?
 
Don't you need an exhaust cycle??? That's why you casn't fire every 360 degrees. unless you're expelling exhaust on the same stroke???
 
First, write down yopu idea in detail. Put in an envelope and mail it to yourself. That will give you some evidence of original thought if someone later patents the idea.

But you shoudln't have told us if you have already.
On the engine part, I like the theory, but I'm too un-experienced to give any further advice.
 
I don't care if someone uses my idea, but thanks for the tip. I'll use it when I have something that is actually worth anything.

The exhaust is automatic, because when the right angle notch in the flank leaves the piston casing, it's out in the open and will disperse before reentering. The exhaust remaining in the piston casing can be removed using a port or something similar slightly above where the piston will be at the bottom of travel.
 
I think we're going to need a much more detailed drawing before we can even comment on your design. I'm having trouble picturing this 'flank'. Where does the actual firing occur? Where the 'flank' is? Do you have a compression cycle? Sounds interesting, but I'm not really getting a clear picture of what you're describing.

The 'flank' is the big circle. It's just a cylinder with a right angle cut out of it. It has a width, for arguments sake 5 cm. The piston's width is also 5 cm across. The compression occurs when the piston is at its lowest point and the flank has just aligned itself with the piston, oh wait, that won't work, the gas would pass out the top right corner while the flank is getting into to combustion location, oh well, another design in the trash can.
