Over the past decade, the increasing air pollution all around the globe as well as the recognition that fossil fuels will not be available forever, have inspired OEMs to develop electrified powertrains. But it also opened the door to investigate new technologies that could significantly improve the ‘old fashioned’ combustion engine regarding both efficiency and emissions.

Whenever new ideas come up, virtual prototyping is an efficient and effective way to get started. The pillars of AVL’s virtual prototyping solution for combustion system development are

• effortless ICE grid generation
• connecting nozzle internal flow and fuel spray in the combustion chamber
• best-in-class spray and wall film models
• accounting for premixed and sooting diffusion combustion
• detecting knock
• precise heat transfer modelling
