Where do I get info on this engine?

This (and many more) designs are a result of people who drank too much as students. The idea was an opposed piston two cycle because of the success of the Jumo engines from WWII. The intake and exhaust ports are at opposite ends of the cylinders. Cylinder blow down between cycles is the best in the diesel business, and you can't overboost it no matter how hard you try. Also you don't need a positive displacement supercharger to make it start or run. It can start and run as a normally aspirated engine. Another problem with OPs is the two very heavy crank shafts required. The Track drum approach eliminates this weight in a system that can be stiffened with modern composit materials. The roller stresses and sizes have been proven in other advanced diesels such as the fuel pump rollers on Pielstich 2.5 and 4.2 engines. The prototype work would be easy for any large machine shop, and only one casting (the cylinder assembly) is required. The major parts are plate stock. The fuel!

p would be from a V6-53 GM diese
l or similar. We have worked out a design for a four cylinder version of the same thing. The displacement (bore size)would be limited by how strong you can make the track case, and how much of a beating the prop hub can take. There would be room for a damping device to drive the prop flange. There are no patents involved. It costs too much to get one. Use any or all of it for free. It is just a fun thing to think about. Have you thought about using half of a rotary for a super charger for the other half? Like a 20B with one section turning up twice the speed with carbon rotors?

None are as simple as the wankel.
