What are the benefits of DPF and DOC retrofits?
DPFs reduce emissions of particulate matter 2.5 (PM2.5), hydrocarbons (HCs), and carbon monoxide (CO) by 60-90%. DPFs require the use of ultra low sulfur diesel fuel (ULSD). DOCs reduce PM2.5 emissions by about 30% as well as reduce emissions of HCs by 50% and CO by 40%. DOCs do not require the use of ULSD. CCVs reduce PM2.5 by 10-15%, HCs by 30-40%, and CO by 50-90%.
