Concept for twin flame licker..

(1/3) > >>

John Hill:


A twin flame licker using an inspiration from the Jan Ridder piston valve method.

As the engine turns one piston coming up pushes its valve piston up which via the linkage pushes the other piston down.

The two cylinders use the same flame and I expect that the exhaust from one cylinder will blow the flame towards the port of the other cylinder, I do not know if this is an advantage or not. :scratch:

If it work, 100% increase in fuel economy! :ddb:  (If it works).

John,

I experimented with two cylinders very similar to what you have suggested. Despite trying flames every which way, it was a total failure, the 'puff' from each cylinder just deformed the flames too much to continue running.
It was fine with two flames on the outside. I eventually went for the 'boxer' type configuration.

The flame shapes are critical with this type of engine, and a tiny bit out of position will stop the engine running.

This is the post I did it all on.

John Hill:
Thanks John,  flames on the outside then! :beer:

John Hill:
I was sitting here dozing in front of TV and I began thinking that if I put an exhaust valve (maybe a ball in a seat on top of the cylinder) there would be much less puff out the other port. :scratch:

NickG:
I can't see the pic but wouldn't the air just take the easiest route and go out of the port rather than open the ball valve though?
