In this study, vehicle exhaust emissions and performance were studied using various renewable components with the aim of achieving a high bio-share in gasoline and compatibility with conventional cars. Several biogasoline components were included in the fuel matrix: ethanol, ETBE, isobutanol, n-butanol and renewable hydrocarbon gasoline produced from hydrotreated oils and fats. The share of bioenergy in the test fuel blends varied from 7 to 28 Eeqv%, and the oxygen content from 0 to 11 m/m%. Fossil gasoline was used as the reference fuel for emissions performance, and E85 fuel as an example of a typical market fuel for FFV cars. Experimental work was carried out at −7 °C with two conventional gasoline cars and one FFV car. The measurements included regulated and unregulated exhaust emissions.
