Summary:

Automobile industry is facing challenges in the field oftechnological innovation and achieving minimum Total cost ofownership despite rise in fuel prices. To overcome these challengesis certainly a daunting task. In doing so, automobile sector ismainly focused on passenger safety, comfort, reliability, meetingstringent emission norms, and above all reducing the fuelconsumption (FC). Referring to the Paris climate agreement,India's commitment to reduce the CO2 intensity by 33% - 35% by2030 below the 2005 levels, it is imperative to lay down strongpolicies and procedure to curb the fuel consumption to contributefor reduction in carbon foot print and oil import. Transportationsector is majorly responsible for the Greenhouse Gas Emission (GHG)of which the CO2 emission from commercial vehicles is nearly 73%,although the sales figures are around 4% of cumulative vehiclesales. Physical testing of these vehicles for FC measurement isvery expensive and laborious task due to number of variantsinvolved in testing. In view of these factors, it is necessary toestablish a very robust simulation based methodology for fuelconsumption/CO2 monitoring of commercial vehicles with GVW of above3.5 tonnes. Countries like US, EU, Canada, Japan and China havealready moved towards simulation based calculations for CO2monitoring and certification. This paper illustrates themethodology for CO2 calculation, which is in harmony with the FCprediction and monitoring procedure available in Europe. Strenuousvehicle (air drag test, coast down) and component (Engine,Transmission, Differential and Tyres) testing were carried out asper defined methodology to generate the detailed vehicle data toprepare the simulation model in VECTO. The results from VECTO arethen compared with the real world fuel consumption measurements andwere found to have good correlation. To make the simulation toolmore compatible with Indian driving and road conditions, it is alsoproposed to develop India specific mission profiles which would bebring in a more holistic approach for fuel consumption calculationby simulation
