Analysis of Performance and Emissions of a Multi-fuel Vehicle

This paper presents the procedure and results of experimental tests performed with a multi-fuel (flex fuel) engine vehicle operating with gasoline, hydrated ethanol (AH), a mixture of the both fuels and, finally, with CNG. A comparison of the vehicle, operating in a chassis dynamometer and using these different fuels is described. It also shows the results of the tests performed with the vehicle after running 17500 km and 32750 km and the differences is presented.
