On-Road Emissions of Conventional and Hybrid Vehicles Running on Neat or Fossil Fuel Blended Alternative Fuels

Fuel consumption is already one of the parameters taken into account for the final ranking of some competitions organized by the Federation International de l¿Automobile (FIA). Pollutant emissions, such as CO, HC and NOx, could also be taken into consideration in the next future. In occasion of a competition organized by the FIA in the framework of the ¿Alternative Energies Cup¿ championship several vehicles were equipped for demonstration purpose with portable emission measurement systems (PEMS) in order to measure the gaseous emission during the competition. The competition took place at the Autodromo Nazionale of Monza on the same track used for the Formula 1 Grand Prix as well. For this competition the track was divided into three sections simulating respectively the driving conditions on urban roads, on extra-urban roads and on motorways. To be admitted to the competition the vehicles had to use either neat alternative fuels or fossil fuels containing at least 50% of alternative fuels like biofuels. Of the nine vehicles monitored during the competition, four were hybrid vehicles using different fuels (gasoline/ethanol, LPG, biodiesel), three vehicles were running on natural gas, one running on LPG and one on biodiesel. The results of the emission measurements are presented and discussed in this paper.
