Facing the stringent constraints on fuel consumption and pollutant emissions, the automotive manufacturers have to produce vehicles with an increasing number of complex systems working together. Numerical simulation for the system design, set-up and control strategies, helps to reduce the development cycle and the global cost.
Existing simulation tools usually do not address, with a high level of details, the various physical domains involved in a vehicle powertrain. To overcome this challenge, IFP and IMAGINE, settled a partnership to develop detailed simulation tools dedicated to performance, consumption and emissions for conventional and hybrid vehicles [1]. These tools are integrated in a multi-domain simulation platform (AMESim®) where several levels of detail can be easily reached for each sub-element.
This paper describes the IFP-Engine and IFP-Exhaust libraries, which are part of this simulation environment and which are dedicated to the detailed simulation of internal combustion engine and exhaust aftertreatment systems. Two application examples, that are widely deployed in Europe, are detailed with experimental validation: turbocharged Diesel engine and Diesel Particulate Filter (DPF).
