  • Catalyst composition for use in a lean NOtrap and method of using
    Patent number: 7749474
    Abstract: A lean NOx trap composition. The lean NOx trap composition utilizes ruthenium in place of higher cost metals such as platinum. The lean NOx trap composition provides high NOx storage efficiency and high NOx conversion efficiency when incorporated in a lean NOx trap. A method of removing harmful gases using the lean NOx trap composition is also described.
    Type: Grant

  • Lean-burn engine exhaust air-fuel and temperature management strategy for improved catalyst durability
    Publication number: 20050115225
    Abstract: A system is described for improving engine and vehicle performance by considering the effects of exhaust conditions on catalyst particle growth. Specifically, engine operation is adjusted to reduce operating in such conditions, and a diagnostic routine is described for determining the effects of any operation that can cause such particle growth. Further, routines are described for controlling various vehicle conditions, such as deceleration fuel shut-off, to reduce effects of the particle growth on emission performance.
