Consistent, Scalable and Open

Exhaust Gas Aftertreatment Simulation

The AVL aftertreatment simulation suite, consisting of the tools AVL BOOST™, AVL CRUISE™ and AVL FIRE™, is a uniquely open and scalable solution. It delivers consistent modeling of all the physics and chemistry that is relevant to exhaust gas aftertreatment systems during each stage of the development process.

The starting point for development and optimization of exhaust gas aftertreatment systems is 1D simulation. AVL BOOST offers unmatched modelling depth, simple model setup and extremely short simulation times – faster than real-time if desired. BOOST solves the very demanding fluid flow, heat transfer and chemical reactions taking place in aftertreatment systems of modern IC engines. To accomplish this, it deploys the most advanced set of physics and chemistry models. BOOST also helps to effectively and efficiently develop and integrate aftertreatment devices with maximum performance, robustness and durability.

For the detailed 3D design of exhaust gas aftertreatment components AVL FIRE offers outstanding capabilities modelling all relevant physics and chemistry. This makes FIRE a crucial element in the design, development and optimization of both diesel and gasoline aftertreatment devices.

Together with AVL BOOST, FIRE forms a unique and dependable 1D/3D solution that can be applied consistently throughout the layout, concept and detailed design stages in both component and system development.

AVL CRUISE, BOOST and FIRE, provide a seamless development approach with the reuse of models and results among tools assuring maximum consistency and efficiency. The aftertreatment system performance data integrated in AVL CRUISE vehicle models are used to predict drive cycle emissions.
