摘要： 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.

摘要： The present invention provides a coarsening resistant automotive exhaust catalyst composition. The composition of the invention comprises a metal or metal-containing compound and a component having alkali metal or an alkaline-earth metal ions bonded to a conjugate base oxide of an inorganic acid. The inorganic acid for which the base oxide is conjugate has a Ka such that the automotive exhaust catalyst composition resists phase transitions that reduce surface area. The present invention also provides a NOx trap which incorporates the exhaust catalyst composition of the invention. Finally, a method of inhibiting coarsening in automotive exhaust catalyst is also provided.
