Fleetguard Emission Solutions™ announced it supplied emission control products under the US EPA clean air initiative in Mexico City, a retrofit program aiming at the reduction of diesel PM emissions. Fleetguard also provided local training and installation support.
The program provided for eight diesel oxidation catalysts (DOC) and twelve diesel particulate filters (DPF). In order to utilize the catalytic diesel particulate filter, the program also provided for ultra low sulfur fuel. The DOCs have been installed on 1991 model year buses. The DOC technology has been verified by the EPA to reduce PM emissions by 20%, CO by 40%, and HC by 50%.
The DPF—the Johnson Matthey Continuously Regenerating Technology (CRT)—was installed on two types of 2001 model year buses. The CRT has been EPA-verified to reduce emissions of PM, CO, and HC by 60%.
In June 2004, the US EPA has awarded $511,000 in grants to the Center for Sustainable Transport, a Mexico City-based non-governmental organization to implement the Mexico retrofit project.
