## page was renamed from Bradley GT/Experimental Prototype Engine = Experimental Prototype Engines = -- GaryHammond -- ~+Click on any thumbnail image to view a larger photo in a new page.+~ 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.

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. [[attachment:prototype-engine-001.jpg|{{attachment:thumbnail-prototype-engine-001.jpg|2 Stroke Prototype Experimental Engine}}|target="_blank"]] ---- This is a Honda cylinder head I modified for an engineer from Caterpillar. It's for a "compound cycle" engine with extra expansion volume.

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.
