Development and validation of a structured analysis tool for pollutant emissions and for consumption of conventional and hybrid motor vehicles based on numerical simulation.
Original Language Title: Développement et validation d'un outil structuré d'analyses des émissions de polluants et de la consommation des véhicules automobiles conventionnels et hybrides basé sur la simulation numérique.
This project aimed at developing, validating and testing a tool for the analysis and support of the design of propulsion systems for conventional and hybrid vehicles. The tool will be developed in order to study, analyse and optimize propulsion systems in terms of consumption and pollutant emissions. It will enable engineers to subdividing the design process by offering different levels of abstraction in relation to the project phase. Thus, it could represent a decision-making tool for decision makers in the automotive sector for technology-related choices in relation to consumptions and emissions.
The project has been structured in two phases.
In the first phase, a series of modules for the simulation of combustion engines were developed and validated.
The second phase a validation of the developed modules was performed.
Several types of engines are considered: atmospheric gas engines, supercharged engines, common-rail diesel engines and direct injection turbocharged petrol engine. The simulators of these systems will be reproduced by assembling the modules developed in the first phase. Experimental measurements performed on these systems and on existing ones, will then allow to readjust and validate the results obtained by the simulator.
