Lightweight design solutions in the automotive field: environmental modelling based on Fuel Reduction Value applied to diesel turbocharged vehicles

چکیده
A tailored model for the assessment of environmental benefits achievable by light-weighting design solutions in the automotive field is presented. The model is based on the Fuel Reduction Value (FRV) coefficient which expresses the Fuel Consumption (FC) saving involved by a 100 kg vehicle mass reduction. The work is composed by two main sections: simulation and environmental modelling. Simulation modelling performs an in-depth calculation of weightinduced FC whose outcome is the FRV evaluated for a wide range of Diesel Turbocharged (DT) vehicle case studies. Environmental modelling converts fuel saving to impact reduction basing on the FRVs obtained by simulations. Results show that for the considered case studies FRV is within the range 0.115-0.143 and 0.142-0.388 l/100km*100kg respectively for mass reduction only and powertrain adaptations (secondary effects). The implementation of FRVs within the environmental modelling represents the added value of the research and makes the model a valuaflexible and tailorable tool for application to realany automotive DT case studies of automotive lightweight LCAy.
