We present a PDE model of three-way catalytic converters used on commercial gasoline-powered vehicles. In order to speed-up simulation times, we developed a fast integration algorithm based partly on a `method of lines' space-discretization, partly on the `met hod of characteristics' for `quasi linear' hyperbolic PDEs, the separation being allowed by a two time scale analysis of the system.

Abstract
We present a PDE model of three-way catalytic converters used on commercial gasoline-powered vehicles. In order to speed-up simulation times, we developed a fast integration algorithm based partly on a `method of lines' space-discretization, partly on the `met hod of characteristics' for `quasi linear' hyperbolic PDEs, the separation being allowed by a two time scale analysis of the system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
