Stricter emission standards in the near future require not only a high conversion efficiency of the toxic air pollutants but also a substantial reduction of the greenhouse gases from automotive exhaus....
“Zoning” a catalytic converter involves placing higher concentrations of platinum group metals (PGM) in the inlet portion of the substrate. This is done to optimize the cost-to-performance tradeoff by....
A SULEV proposal was investigated for a Hyundai Elantra 1.8L Nu Engine, combining advanced catalyst technologies with optimized engine management control. A washcoat system using 20% less PGM loading ....
A commercial three-way catalyst (TWC) was evaluated for ammonia (NH3) generation on a 2.0-liter BMW lean burn gasoline direct injection engine as a component in a passive ammonia selective catalytic r....
The effect of various fuel-cut agings, on a Volvo Cars 4-cylinder gasoline engine, with bimetallic three-way catalysts (TWCs) was examined. Deactivation during retardation fuel-cut (low load) and acce....
Among the platinum group metals (PGMs), rhodium (Rh) is known as an exceedingly valuable element for automotive catalysts due to its powerful catalytic function. Because Rh is a costly material, it is....
Platinum Group Metal (PGM) use is dominated by the automotive industry. The PGM market is sensitive to shifts in the drivers for emission control and the delicate supply-demand balance. Technology shi....
