Your Choice if Quality Matters



Virtual Engine Development

AVL BOOST™ is a fully integrated IC engine simulation software. It delivers advanced models enabling accurate prediction of engine performance, tailpipe emissions and acoustics.


The Challenge

Engine Performance

  • Can I re-use my collected 1D data from the concept phase for more detailed 3D modelling and vice versa?
  • Can I optimize the transient response considering mechanical inertia and gas dynamic effects (eg. turbolag)?


Exhaust Gas Aftertreatment

  • How closely do the simulation results correlate with real world driving emissions (RDE)?
  • Can I calculate individual components as well as the whole exhaust aftertreatment system?


Duct Acoustics

  • Can I predict orifice noise and design brandsound?
  • Can I calculate linear acoustic simulation without requiring additional engine data?


The AVL Solution

AVL BOOST provides a comprehensive species transport for a high level of flexibility regarding fuel composition and working gas. This is accomplished with an internal solver for chemical reactions. Coupled with AVL FIRE users are able to accurately account for 3D flow and heat transfer effects in pipes, manifolds and combustion chamber. Identical modelling of physics and chemistry in aftertreatment systems empowers engineers, designers and developers to seamlessly switch between 1D and 3D models at any stage of the development phase. The flexible AVL BOOST 3D-approach to simulate linear acoustics delivers highly accurate solutions even in high frequency ranges.


The Added Value

  • High-level support by AVL engineers located worldwide
  • Software development and advancement driven by AVL powertrain expertise
  • Consistent 1D and 3D aftertreatment simulation in AVL BOOST, AVL FIRE and AVL CRUISE
  • Easy integration into third party environments
