With upcoming US Tier 3/LEV III emissions regulation set for full implementation in 2025, significant efforts are being made within the industry to meet the fleet average SULEV30 requirement. Under the current vehicle technology, cold-start emissions generated in the first sixty seconds can make up to 70+% of total tailpipe emission over the FTP-75 certification cycle. Therefore, the improvement in the performance of catalyzed substrates during cold-start becomes essential for total tailpipe emissions reduction. Low-mass substrate technology offers a significant reduction in time to light-off, enabling a reduction in cold-start emissions while meeting customer mechanical durability and thermo-mechanical requirements.
