Engine Noise Signature Recovery


The Need

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.

The Project

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.

The Benefit

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.
