MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

New substrates are designed with thinner walls or higher porosity, which allows the coating of better catalysts without sacrificing durability. This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010.

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

The MECA assessment is based on the implementation timeline presented by CARB staff at a January 2019 public workshop as well as the assumptions laid out in the CARB staff white paper released in April 2019. The cost of controlling NO x to 0.05 g/bhp-hr in 2024 and to 0.02
