engine emissions
An Expansive Portfolio of Catalytic Technology
Top Tier Technology to Serve the Internal Combustion Engine Market
The four key harmful byproducts of combustion engines are hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), and Particulate Matter (PM or soot)
Depending on the fuel type and the design of the engine operation, different emission catalysts can be utilized to treat these byproducts
Spark Ignition engines typically use gasoline or natural gas as fuel and require a three way catalyst (TWC) to treat emission products
Compression Ignited engines often use diesel as fuel and may require up to four separate catalysts to treat emissions. Those catalysts are typically Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) and Ammonia Slip Catalyst (ASC)
CDTi has over 20+ Years of TWC Catalyst Technology Development and Product Manufacturing
We have focused on development of technologies to drive catalyst performance while reducing use of Precious Group Metals (PGM) as such as Platinum (Pt), Palladium (Pd), and Rhodium (Rh).
Over 20+ years, we have manufactured over 14 million catalysts for passenger cars, supplied to global OEMs
CDTi offers a variety of technologies and products to address diesel emission systems. These can be provided as stand-alone components, or integrated into complete Aftertreatment systems. These are designed for On-Road, Off-Road, Stationary and Industrial applications
– Diesel oxidation catalyst (DOC), with low NO2 selectivity where appropriate for application
– Catalyzed and Uncatalyzed Diesel particulate filter (DPF), with or without Active Regeneration system
– Bi functional catalyst which can function as both selective catalytic reduction (SCR) and ammonia slip catalyst (ASC)
