Clean Diesel Technologies

Clean Diesel Technologies was an American automotive emissions-control company established in 1996 and based in Ventura, California. Its business centered on technologies intended to reduce pollution from internal-combustion engines, particularly diesel engines used in heavy-duty highway vehicles and off-road equipment. The company operated through two principal areas: a Heavy Duty Diesel Systems division focused on exhaust-emission control devices, and a Catalyst division focused on catalysts and related materials used to reduce pollutants. The company’s work addressed the technical and regulatory challenge of lowering emissions from existing diesel fleets. Rather than concentrating only on new vehicle powertrains, its products were designed for use with in-service engines and exhaust systems. The company’s portfolio included systems associated with exhaust-gas recirculation and particulate or broader exhaust-emissions control, as well as catalyst technologies and a diesel-soluble additive. Its proprietary intellectual property included MPC, described as a catalyst-manufacturing process, and Platinum Plus, a diesel fuel additive intended to support emissions reduction. Clean Diesel Technologies stated that its products had received verification from the United States Environmental Protection Agency. EPA verification was important because it provided a regulatory basis for the use of emissions-control technologies in designated engine and vehicle applications. The company’s systems were reported as being used with highway automobile engines, while some products were also developed for off-road applications. The company expanded beyond its United States base through operations or subsidiaries in Canada, France, Japan, and Sweden. In September 2012, the company and its subsidiaries changed their names to CDTi and operated under that name. The renamed organization was subsequently described as CDTi Advanced Materials, Inc., although the available reference material does not establish the company’s current operating status, ownership, or corporate structure. A notable product-development milestone came in December 2013, when Purifilter EGR and the off-road Purifilter OR received EPA verification. These products applied the company’s MPC technology to exhaust-emissions control and were described as suitable for a majority of heavy highway engines in the United States. The company’s 2012 revenue was reported as $60.5 million, with the Catalyst division recording 40.5 percent growth that year; these figures are included only as historical context and do not establish present financial performance. Clean Diesel Technologies occupied a specialized position in the emissions-control sector. Its proposition combined proprietary catalyst manufacturing, retrofit-oriented exhaust systems, and fuel-additive technology for diesel engines. The available sources provide limited information about later products, management, ownership, or market activity, so the company’s present brand status and business operations require further verification.

Clean Diesel Technologies was founded in 1996 in the United States, with headquarters in Ventura, California. The company developed products for controlling pollution from diesel and other internal-combustion engines. Its activities were organized around two main divisions: Heavy Duty Diesel Systems, which developed and produced exhaust-emission control devices, and Catalyst, which developed catalysts used to reduce vehicle emissions. The company’s business addressed both engineering and regulatory requirements. Diesel engines produce pollutants through combustion and exhaust, and emissions-control systems must be matched to engine type, duty cycle, fuel, and applicable standards. Clean Diesel Technologies therefore pursued a portfolio that included exhaust-treatment hardware, catalyst materials, and additives intended to improve emissions performance. Its technology base included MPC, a proprietary catalyst-manufacturing process, and Platinum Plus, described as a diesel-soluble additive. The company’s products were associated with highway vehicle engines and with applications for heavy-duty and light-duty diesel equipment. It also developed systems for off-road engines, extending its potential market beyond conventional road vehicles. According to the available reference material, the company operated primarily in the United States while also maintaining operations or subsidiaries in Canada, France, Japan, and Sweden. In September 2012, Clean Diesel Technologies and its subsidiaries changed their names to CDTi and operated under that identity. The company was later described as CDTi Advanced Materials, Inc. The available material does not provide enough information to determine the exact legal sequence of later corporate changes, the current ownership structure, or whether the original brand remains commercially active. The company reported $60.5 million in revenue for 2012, while its Catalyst division grew by 40.5 percent during that year. These figures illustrate the scale and direction of the business at that historical point, but no current financial information is established by the supplied sources. A major technical and regulatory milestone occurred in December 2013. Purifilter EGR and the off-road Purifilter OR, both developed using MPC technology, received verification from the United States Environmental Protection Agency. The verification indicated that the products could be used with a majority of heavy highway engines in the United States, subject to the applicable verification conditions. This recognition supported the company’s positioning as a supplier of retrofit and emissions-control solutions for existing diesel fleets. Clean Diesel Technologies’ historical identity was therefore tied to emissions reduction rather than vehicle manufacturing. Its product strategy combined catalyst development, exhaust-gas treatment, and diesel-fuel additives. The record available for this dossier contains little information about executives, subsequent product generations, later corporate transactions, or present-day operations; those areas remain open for research.
