Cylindrical Energy Module

The Cylindrical Energy Module or CEM Rotary Pump is a modified swash-plate pump. The rotating rotor assembly are moved back and forth via piston drive pins which follow a stationary Sinusoidal Cam Track that encircles the rotor assembly.

The CEM Engine will be capable of delivering substantially greater performance with greatly reduced manufacturing cost. A novel concept for significantly increasing the efficiency of the four-stroke cycle internal combustion engine, the Department of Defense in 1997 awarded the engine concept an SBIR. The super-charged CEM Engine has the potential to become one of the first self-lubricating, air-cooled, multi-fuel, four-stroke cycle engines to deliver two horsepower/pound.

The pump/compressor/engine was invented by Eddie Paul, president of EP Industries in El Segundo, CA. (patented in 1993)

Highlights of pump design:

• Only 7 moving parts
• Virtually clog-free operation
• Its weight is about one-sixth that of an equal-capacity unit
• Its output is 24 times that of most pumps or compressors of equal bore and stroke, and twice that of most engines.
• Can be made out of thermoplastics for light weight uses.

The new pump design has been used in fire extinguishers, as well as mobile biological and chemical control units for the US military.

The CEM also has been announced to be used as the new motor power-plant for the Duesenberg Torpedo Coupe. With expected market introduction in mid 2008.
