The introduction of the GPF has created a new challenge for gasoline engines. Recovering the engine noise signature while balancing performance and emissions requires a multidisciplinary and innovative approach from NVH teams.
BlueThink carried out a group od Resident Consultants with experience in NVH. The project involved the realisation of a simplified model able to predict the behaviour of the GPF in different conditions. This allowed the team to run optimisation algorithm.
This approach associated with in-sector expertise allowed the client to reach several expected and unexpected results, such as: better engine signature, GPF performance optimisation and lower cost of the component.
