Clean Diesel Technologies is an emissions control company.

Are you looking for a cleantech emissions control company to reduce diesel emissions and lower the carbon intensity of on- and off-road engine applications?

You are in the right place. Here at CDTi (NASDAQ: CDTI), we design, develop, manufacture and distribute heavy-duty diesel and light-duty vehicle emissions control systems and products to major automakers and retrofitters worldwide.

Driven by increasingly stringent global emission standards for internal combustion engines, and without increasing secondary emissions such as nitrogen dioxide (NO2), we help significantly reduce harmful emissions formed by the combustion of fossil fuels and biofuels such as:

• Particulate matter (PM), or soot, that can cause serious health problems;
• Oxides of nitrogen (NOx) that produce smog;
• Hydrocarbons (HC) that cause adverse health effects; and
• Carbon monoxide (CO) which reduces oxygen delivery within the body.

Our Heavy Duty Diesel Systems Division specializes in the design and manufacture of verified exhaust emission control solutions. And our Catalyst Division produces catalyst formulations for reducing emissions from gasoline, diesel, and natural gas combustion engines.

CDTi has over 30 years of global experience in vehicle emissions control technologies. We offer one of the industry's most comprehensive portfolios of evaluated and EPA- and CARB-approved emissions control systems for use by aftermarket and retrofit programs, as well as OEMs around the world.

Please look around the site for additional information. If you have any questions, do not hesitate to contact us. We look forward to helping you and continuing to reduce emissions and harmful pollutants worldwide.
