Translating Motion - Which is the most efficient?

[Chantry09]

Hi.

I need some wisdom! Here is my problem. I want to make an air powered engine. This isn't a problem, I have plans for this. However, I want to put my own twist on the engine. I want it to be a axial engine, so the axle is in the same plane as the cylinders.

The importance factor is efficiency, I want this mechanism to convert the energy as efficiently as possible, translating to low start-up torque and high RPM output.

There seems to be a few ways to do this, so if I put down some of my options, can you advise me on the best route.

Option 1. Swatch Plate

Option 2. Trebert

Option 3. Wobble Plate

Option 4. Barrel Cam

Option 5. Radial Engine (I know, the cylinders arnt in the same plane as axle)

Option 6. None of the above!

Id be really interested to hear what your thoughts are on this, and input would be hugely appreciated.

how many rpm do you want to get?

Pretty interesting and clever design ideas you've found.

Hi! Thank you, it took me a while to find them. I am looking to get around 2000-3000rpm
