Panels show (a) PM 2.5 , (b) elemental carbon (EC), (c) NO x , (d) CO, (e) formaldehyde, and (f) sum of target VOCs. Among the findings were that at idle, B20 increased engine-out and DOC-out emission rates of CO, NMHC, PM 2.5 , elemental carbon (EC), formaldehyde, benzene, and other VOCs (volatile organic compounds) for both the 1.7
