The Dyna-Cam.

Prepare yourself for a look at the future...

The engine is 13" in diameter, 40" long and weighs 265 pounds with basic accessories. It has unique features and major benefits over conventional engines of similar weight and power. The benefits include lower manufacturing costs in equal production, 50% smaller size, 50% fewer replacement parts, better fuel economy, smoother operation, lighter weight, plus nearly 100% higher torque enabling the engine to turn high efficiency propellers with lower noise output.

The engine has two identical cylindrical blocks that each have six cylinders arranged parallel around the main shaft located in the center. Cylinders of both blocks line up so that six double-ended pistons can fire back and forth between the aligned cylinders of each block Each free floating piston is cut away on the central interior side and fits with precision around a 9" diameter, four lobe, sinusoidal cam that is keyed to the main shaft.

As the pistons fire back and forth, the main cam rolls through the pistons causing the central shaft to turn. All moving surfaces are roller bearing surfaces. Another smaller 5" cam is attached to the main shaft at the outer end of each block. As each valve cam turns, it pushes against hydraulic lifters which push against the poppet valves inside each cylinder head.

The engine is a 4-stroke engine. Because of the design of the main cam, each of the twelve cylinders fires with every revolution of the shaft, in contrast to three times with conventional six-cylinder engines. The engine can be described as a free piston, axially cam-drive engine.
