Virtual development ICE performance and emissions

Thermal Load Simulation

Optimized engines for emission reduction and high performance

ICE-based Powertrain

Modern engines feature compact and lightweight designs, potentially exposing them to high thermal loads. This could lead to fatigue issues and component failures if they haven’t been correctly optimized.

At AVL our thermal load and thermal management solution is used to test an array of factors to determine what is needed. We check everything from the release of heat in the combustion chamber to the chemical reactions in exhaust gas aftertreatment devices. We also test the thermal flow in the under-hood compartment, flow and heat transfer in cooling and oil circuits and heat transfer between fluids and structures. This solution is applicable at the component, assembly and system level.

Liner Cavitation

Erosion due to cavitation may cause irreparable damage to an Internal Combustion Engine (ICE) with a wetted liner. This - more often than not - leads to fatal failure. We have therefore developed a simulation solution that enables engineers to compute the interaction of piston slap and cavitation. This helps to identify erosion areas and define measures to combat the potential critical conditions this would otherwise lead to.


Quenching, as part of the heat treatment process, significantly impacts material strength and component durability.

We offer predictive solutions to combat this. By computing the transient temperature field of quenched parts, we can help you to determine deformation and stress. Utilizing these simulation results also means that we can optimize the design and thermal treatment process to minimize residual stress.
