Brazilian energetic matrix is based on two fuels: gasoline (E22: 78% pure gasoline + 22% anhydrous ethanol) and ethanol (E100: 93% anhydrous ethanol + 7% water).
A Flex Fuel 2-wheeler (motorcycle) engine management software strategy was developed in order to meet Brazilian market demand based on the energetic matrix mentioned above and a worldwide market forecast growth in the corresponding small engines segment.
As 2-wheeler engine configuration and electric architecture is simpler than passenger cars, a premise was established: to develop a completely new Flex Fuel system for the 2-wheeler segment with functionalities simpler and easier to calibrate than actual concept used for Flex Fuel passenger cars.
This paper presents the result of this study: a Flex Fuel system able to operate with gasoline (E22), ethanol (E100) or any mixture of both fuels with similar behavior in an easy-to-calibrate system.
