The introduction of the GPF created a new challenge for gasoline engines. Recovering the engine noise signature while balancing performance and emissions requires a multidisciplinary and innovative approach to be adopted by the NVH teams.
BlueThink dedicated to the project a group of Resident Consultants with experience in NVH. The project involved the realization of a simplified model able to predict the behaviour of the GPF in different conditions. This allowed the team to run and test an optimization algorithm.
This approach associated with in-sector expertise allowed the client to reach a number of results, both expected and unexpected, among which: better engine signature, GPF performance optimization, lower cost of the components.
