About Us


CDTi actively develops advanced catalyst technologies as well as designs and manufactures emissions control systems for vehicles and heavy-duty equipment.

Advanced catalyst technologies from CDTi are highly differentiated from competitors because they offer similar or better performance while using comparatively little or no precious metals. Our Catalyst Division has supplied over 11 million catalyst parts to light duty vehicle customers since 1996. Our Heavy Duty Diesel Systems Division products include our Engine Control Systems-branded products for the retrofit and OEM markets.

Advancing Emissions Catalyst Development

CDTi's Catalyst Division serves the light duty vehicle market, including OEMs such as Honda, as well as the heavy duty diesel equipment retrofit, replacement and OEM segments, with customers such as Cummins and Navistar.

This is where we sell our proprietary, low-platinum group metals advanced catalytic coatings which accelerate the breakdown of exhaust gasses. Globally, this market is estimated to reach $7.7 billion by 2017, according to a report issued by Global Industry Analysts, Inc.

We currently supply our catalyst products featuring our proprietary MPC®, ARIS®, Platinum Plus® and EGR/SCR technologies for a variety of applications across vehicle and equipment market segments.

Designing and Building Proven Emissions Control Systems

The Heavy Duty Diesel Systems Division of CDTi is a global manufacturer and distributor of verified heavy duty diesel emissions control systems and products to major OEMs and retrofitters.

Internal combustion engines with diesel exhaust are major sources of a variety of harmful pollutants. Sales of emission control systems by our Heavy Duty Diesel Systems Division are driven by increased regulation of diesel emissions, particularly in the State of California and Europe's Low Emission Zones, or LEZs. The U.S. Environmental Protection Agency, or EPA, estimates that more than 11 million diesel engines operating today do not meet its new clean diesel standards.

We have over 35 years experience in vehicle emissions control technologies - offering one of the industry's most comprehensive emissions control portfolios of evaluated and EPA and California Air Resources Board, or CARB, verified systems for use in engine retrofit programs, as well as by regulators in several European countries.
