Latin America's Experience with Diesel Catalytic Purifiers for Urban Buses

Recently, 3000 catalytic purifiers have been sold into Santiago, Chile, for use on urban buses. The sale into Santiago resulted from over two years of demonstrating the performance of diesel catalytic purifiers in various Latin American countries.

This paper highlights the results of the demonstrations including a variety of engine-types, opacity reductions provided by the use of purifiers, preliminary durability data and the present status of the use of catalytic technology in Latin America.
