Tightening regulations on CO_2 emissions and tough acoustic targets are driving the need for advanced engine bay solutions in the automotive industry. In this context, engine encapsulation is one of the most interesting compromises meeting all these aspects, and consists of a capsule surrounding the engine. From an NVH perspective, understanding how different design choices will impact the performance is key to by-pass the costly and time-demanding building-testing-optimizing process, especially in an early design stage. In this direction, the paper focuses on how numerical methods can support and guide engineering in addressing the influence of different design parameters towards an overall improved vehicle NVH performance. Firstly, an introduction on the different types of engine encapsulation configurations is given with an overview of their performances. Secondly, it is shown how CAE tools can support product development, both at component and vehicle level.
