About EnerTeck Chemical Corp.

EnerTeck Chemical Corp. is the wholly owned, operating subsidiary of EnerTeck Corporation, a Company focused on the development and/or acquisition of combustion enhancement, emission reduction, and other environmentally friendly technologies. EnerTeck's diesel fuel specific combustion catalysts, EnerBurn and EC5931A, form a non-hazardous, nano-catalyst surface on the diesel combustion chamber and piston heads. This catalyst lowers the combustion temperature of carbon and accelerates oxidation, which enhances the burn rate of diesel fuel in engines. Current users experience increased fuel economy of between 8-15%, reduced engine wear of 30-50%, and increased brake horsepower of approximately 4%. EnerBurn's verifiable impact on the environment includes decreased highway smoke of 25-70% and reduced NOx emissions of 10-20%. This technology was originally introduced commercially by Nalco/Exxon Energy Chemicals, LP, a joint venture between Nalco Chemical Corporation and Exxon Corporation.
