The CEM Engine
Innovation and simplicity of design
The Cylindrical Energy Module Engine or CEM is a new technology for a more efficient conversion of power from fuel. The basic CEM Pump concept was invented and patented in 1991 by Eddie Paul. Using this basic CEM design, pumps were and continue to be fabricated and sold and are used with exceptional success in many fields including the Department of Forestry as a CAFs pump (Compressed Air Foam system). The CEM design provides a positive displacement designed to function at each end of the CEM unit. This duel-ended design doubles the output without doubling the size or weight of the basic unit. Each piston is driven around the two fixed outer sinusoidal cam halves, i.e., within the gap between the cam halves, with each piston driven by its centrally mounted trunion pin and drive roller. This allows each end of each piston to perform double compression cycles on each end of the CEM unit. CEM effectively has 12-cylinders with only six double-ended pistons allowing 12 full 4 stroke cycles per single revolution of the drive shaft. The CEM also uses ports (the same diameter as the cylinder and piston) instead of valves, with a single combustion “area” at one location on the head, on each end of the units, with the inner cylindrical block and pistons rotating past the combustion area on each head during combustion. This allows the CEM to have one combustion area per six pistons per end. This inner block containing the pistons also rotates past the exhaust port during the exhaust phase and proceeds to the intake port for more fuel/air. Again, this is happening on both ends of the unit at 90 degrees out of phase to one another. The CEM inner block will only rotate 360 degrees to perform each complete power stroke. This gives us the power package of a 2-cycle engine with the clean burning aspects of the four stroke cycle engine. This translates into twice the power in the same degrees of rotation. Most automotive engines are either four, six or eight cylinder whereas the CEM is a 12 cylinder engine, but fits well within the footprint of the smallest four cylinder engine with a much easier to fit profile (cylindrical shape as opposed to rectangular).
Clearly, due to the simplicity of design and low number of moving parts, the CEM-E will have lower manufacturing cost. Marketability
A small, light weight, economical engine should speak for itself. But economy is the driving force behind the marketability of the CEM. We also believe that our engine design will allow us to obtain the 100 miles per gallon milestone that everyone is trying to achieve.
Because the CEM will weigh about one third of an equal horsepower engine, the cost of manufacturing should be at least one third.
