Hypothetical 2 stroke v-8

[brainstatic]

Here is a link to a great wealth of information on two-cycle model engines:
http://modelenginenews.org/index.html
The fellow publishes monthly. There are discussions pertaining to reedless designs of radial two stroke engines, and other ways round the pump problem.

Also, are you still considering having the crankcase separate from the induction system? If you are, then whilst the piston is at TDC, won't the pressurized fuel/air mixture pump past the piston into the crankcase, accumulating the fuel there? I have seen one two stroke engine with an additional "oil-type" ring at the piston skirt to avoid this very problem, it is called the Deltic. Even so, when using nitromethane (aka nitro) fuel, the major constituent methanol is able to bypass any viable method of compression seal. It then incorporates into the lubricant, and thus destroying it via thinning, as well as other harmful solvent effects. This does take a while though, and changing the oil frequently remedies.

Search Google for the model Deltic builder, his name is Clen. He also uses the turbosupercharger, the best design for two-stroke V-engine configurations.

For more information on the turbosupercharger, look for the Wasp engines by Pratt & Whitney. Their gearing and ultimate speeds can be converted and scaled to your application within a standard error or two. After that, you could model it using differential equations for a closer approximation. Peer reviewed engineering journals contain the protocol for this conversion too.

Hope this helps,

Thanks Braintastic for the awesome links. Progress has been slow with the cad work lately due to my work shedule, but I always think of ways to make this engine a reality. I think to start off, I will build the engine using the supercharger to pressurize the entire crankcase to make it relatively easy to build. This way it should still have the characteristics of any "normal" single cyl engine, there will just be 8 cylinders. It will also eliminate the need to have a seperate oiling system for the bottom end. I don't think the constant pressure in the crankcase will cause any problems, but it may. Thanks again for the good links.
