About the Cover
Cordierite and silicon carbide ceramics are frequently used in particulate traps to control particulate emissions from diesel engines. SwRI engineers are investigating the use of traps, in combination with technologies that reduce oxides of nitrogen emissions, to meet tighter emission regulations just three years over the horizon.
