Clean Diesel Technologies and Engelhard report NOx reductions of 75-90 percent in demonstration of new diesel engine emission-control system.STAMFORD, Conn.--(BUSINESS WIRE)--May 28, 1997--Clean Diesel Technologies Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CDTI CDTI Centro Para el Desarrollo Tecnológico Industrial (Spain) CDTI Cockpit Display of Traffic Information CDTI Common rail Diesel Turbo Injection CDTI Commercial Driver Training Institute (Pakistan) ) and Engelhard Corp. (NYSE NYSE See: New York Stock Exchange :EC) Wednesday announced that recent tests of advanced urea SCR (Sequence Control Register) See program counter. technology on a 230 Hp Cummins "B Series" diesel engine showed emissions of nitrogen oxides (NOx) were reduced by 75 to 90 percent over a range of conditions. The demonstration was part of a joint development program among Clean Diesel Technologies (CDT CDT abbr. Central Daylight Time CDT Central Daylight Time CDT n abbr (US) (= Central Daylight Time) → hora de verano del centro; (BRIT ), Engelhard Corp., and Nalco Fuel Tech (NFT NFT - Network File Transfer. An INTERLINK command on CERNVM. ) to develop a cost-effective, high-NOx reduction technology for stationary diesel engines. CDT and NFT supplied reagent metering and proprietary injection equipment based on their well-proven NOxOUT SCR design for the demonstration, while Engelhard provided its advanced ZNX catalyst and directed the engine tests at its Union, N.J. engine laboratory. The next step in the development program is a commercial field demonstration, planned for this summer, to confirm system durability and performance under field conditions. Urea SCR involves the controlled injection of non-toxic, water-based urea reagents into the exhaust gas Exhaust gas is flue gas which occurs as a result of the combustion of fuels such as natural gas, gasoline/petrol, diesel, fuel oil or coal. It is discharged into the atmosphere through an exhaust pipe or flue gas stack. of a diesel engine, where they selectively react across a catalyst to convert NOx to water and elemental nitrogen. The catalyst can also be designed to reduce hydrocarbon and carbon monoxide carbon monoxide, chemical compound, CO, a colorless, odorless, tasteless, extremely poisonous gas that is less dense than air under ordinary conditions. It is very slightly soluble in water and burns in air with a characteristic blue flame, producing carbon dioxide; emissions. The urea systems use a non-toxic, readily available reagent. "The excellent emission-control performance and nearly 100 percent utilization of reagent offer promise that engine manufacturers and end users will be able to optimize engine timing for maximum fuel economy and lowest particulates, while effectively controlling NOx," said Denise Viola, general manager, Heavy-Duty Power Systems at Engelhard. Currently, many engine-design techniques that reduce NOx do so with an increase in particulates and increased fuel consumption. "Although the demonstration was conducted on a 230 Hp engine typical of medium-duty diesel vehicles, the conditions evaluated closely match those of larger engines used in stationary power generation," said CDT Chief Operating Officer Chief Operating Officer (COO) The officer of a firm responsible for day-to-day management, usually the president or an executive vice-president. Jim Valentine. "I'm confident that we will be able to develop this technology as a cost effective control strategy for use with new OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and diesel-powered generator sets." Other advantages to the new urea SCR system include a modular design concept that is expected to have low initial capital costs and be easily installed. Urea reagents used in the process are widely available through licensed NOxOUT distributors. Urea consumption is approximately two to five percent of fuel flow. CDT is a development-stage company engaged in the commercialization of diesel emission control technologies. Its primary focus is on commercializing its proprietary platinum fuel catalyst and advanced NOx control technologies. Engelhard Corp. is a world-leading provider of environment technologies, specialty chemical products, engineered materials and related services. Nalco Fuel Tech, a 50/50 joint venture between Fuel-Tech N.V. and Nalco Chemical Co., is the leading supplier of the urea-based NOxOUT process for control of nitrogen oxide emissions from boilers, process heaters and waste combustors. There are more than 220 NOxOUT systems installed worldwide. CONTACT: Allen & Caron Inc.
