NVH Engineering for Large Engines

Mainly vibrations are the big topic for large engines. Especially for singly cylinder setups the testing layout has to be designed carefully to allow operation over the complete targeted engine speed range without running into resonances. Additionally NVH could be used for monitoring large engines and detect necessary maintenance before the engine is damaged.

AVL Approach

The AVL Acoustic Engineering team is prepared to support our customers and to provide latest NVH development tools and methodologies, NVH facilities and engineering capabilities to develop individual solutions for and together with our customer. The major services of AVL focusing on NVH development are:
  • Single Cylinder Engine Setup
  • Engine Monitoring and Detection of Possible Malfunction
  • Large Engine Development
  • Vehicle NVH Refinement
  • NVH Powertrain Integration
  • Vehicle and Powertrain NVH Simulation
  • Sound Engineering
  • NVH Software and Methodology Development
The excellent know-how and innovative ideas as well as the strong link of the NVH team to other skill teams within AVL, enforces the outcome of every single project individually and generates an additional benefit for our customers.
