Corona Discharge Device

The Litex CDD is a new, inexpensive product, which significantly reduces hazardous emissions generated by gasoline-powered automobile engines.

The CDD is inserted into the exhaust system of a gasoline engine upstream from the three-way catalytic converter, and is capable of reducing carbon monoxide (CO) emissions more than 80 percent, and hydrocarbon (HC) and oxides of nitrogen (NOx) emissions by more than 50 percent, depending upon the sulfur contents of the fuels involved, which may range from 0 to more than 300 ppm (parts per million).

The CDD will be manufactured by Saturn Electronics & Engineering, an Auburn, Michigan American supplier to the automotive industry. It is currently available to auto manufacturers for testing. The production version will be available to automotive manufacturers in the year 2000.

Volume price of the CDD to automotive manufacturers is expected to be less than $100. The new device is both readily installed on new cars during assembly and suitable for retrofitting older cars.

The CDD is a low-power device that will operate at approximately 25 watts — less than the amount of power required to illuminate a car’s brake light.

The CDD is based on a technology initiated and patented by the Lockheed Martin Corp. Litex has exclusive rights to the Lockheed Martin patent, and has further developed the technology with additional research and patents of its own. The product has been undergoing extensive testing since 1997 in the laboratories of Arthur D. Little, Inc. of Cambridge, Massachusetts, a renowned research and development firm. Additional testing is being conducted by international automobile manufacturers and independent organizations.
