As a heritage from Diesel vehicles, the EURO 6 Light Duty emission standards introduced limits for particle number (PN) of GDI engines. Given the concern of the extremely small particles on health effect, the same limits were set (6.0 x 1011 #/km) for both diesel and GDI cars. In Brazil, the current phase for light vehicles of PROCONVE L6 enforced particulate matter (PM) mass emission standard for Diesel vehicles only, applying the limits of 25 mg/km for passenger cars and 30 mg/km for commercial vehicles. Similar to the European concern, even not considering yet the particle number (PN) emissions, future Brazilian phase L7, which is under study, considers a significant reduction on the limit of the particulate matter (PM) mass emission, from current limits down to 6 mg/km for both Diesel and DI engines, for passenger and commercial vehicles. In the goal of generating reference data to foster the important discussion of (PN) emissions in Brazilian passenger vehicles, this article discusses (PN) measurements of Flex-Fuel Vehicles equipped with direct injection (DI) and port fuel injection (PFI) engines, fueled with ethanol (E100) and gasohol (E22). The mechanisms and parameters which influence the particulates formation are discussed according to the bibliography and the advantages that Ethanol usage brings to human health is highlighted. This study shows interesting comparative results of (PN) and can be used as reference for future emissions regulations of Flex-Fuel vehicles in Brazilian market.
