Experimental Prototype Engines

Photos of modifications I made to an air cooled VW engine to make it conform to my patent #3,672,172. This is my 4-stroke prototype engine. It was installed in the Bradley GT for a while and everything worked as I envisioned except for the air/oil separator. I was never able to successfully separate the entrained lubricating oil from the induction air stream, and eventually shelved the project. I then built up a more conventional engine to put in the Bradley.

This is a 2-stroke engine modified according to my patent. It started out life as a 1950 Mercury outboard motor. It was a 40 cubic inch model KF9. (The very first model four cylinder engine ever built by Mercury.) Everything on this 2-stroke prototype worked as I envisioned, including the air/oil separator. I ran it both with a supercharger and without a supercharger.

2 Stroke Prototype Experimental Engine

This is a Honda cylinder head I modified for an engineer from Caterpillar. It's for a "compound cycle" engine with extra expansion volume.

These are my patent drawings.

These are patent drawings for someone else's engine that is very similar to mine. It shows an improved air/oil separator to what I was using. Combined with some further internal engine modifications, I think this improved design separator would solve the problems I had with my original 4-stroke prototype.
