Study of Modern Application Strategies for Catalytic Aftertreatment Demonstrated on a Production V6 Engine

A study was performed to develop optimum design strategies for a production V6 engine to maximize catalyst performance at minimum pressure loss and at minimum cost. Test results for an advanced system, designed to meet future emission limits on a production V6 vehicle, are presented based on FTP testing. The online pressure loss and temperature data serves to explain the functioning of the catalyst.
