Re: Duke Engines
I'd be really interested to see how they have designed the sliding seals that seal at 15:1 compression a rotating block against a stationary head!!

Re: Duke Engines
Very clever piece of engineering, I'd guess the idea came from axial piston hydraulic pumps and motors - very similar concept, it's a shame they didn't give a bit more detail for some of the problem areas but I guess that would be giving away the farm. Hope they do well with it, although looking at their website & Facewipe acc not a lot seems to have changed for a while.

Re: Duke Engines
Exactly my thoughts Deegee. I used to overhaul variable displacement hydraulic pumps for Skyhawks aircraft and they had a cylinder to valve head metal to metal seal (4500 psi test press). I had to lap the mating faces to 3 helium light bands of smoothness. QA was with a 40x microscope. That's what made me wonder how they did it.Deegee wrote:Very clever piece of engineering, I'd guess the idea came from axial piston hydraulic pumps and motors - very similar concept, it's a shame they didn't give a bit more detail for some of the problem areas but I guess that would be giving away the farm.

It's a great idea but a bit late for automotive as electric is the money pit for R&D. Unless these are adapted as hybrid units. But lots of scope for industrial or aeronautical use imo.

Re: Duke Engines
Yup I knew it was pretty extreme (22 years ago I was doing that) The lapping plate got sent away for a calibration check every year, but we just checked under a 40x microscope and when the components looked like polished granite you knew it was up to spec.Monty wrote:Had to look that up, 1 is 0.0000116 inches!
