Typical runtime for 20 cycles at 6000 RPM on a modern laptop: ~45 seconds.

For large‑scale parametric studies, consider using AVL Boost Design Explorer. This module automatically runs many simulations (e.g., varying valve timing, compression ratio, boost pressure) while keeping your UPD‑defined combustion fixed. It then applies optimization algorithms to find the best combination of parameters that meets your targets (power, fuel consumption, emissions).

Building a model requires logical progression from ambient air intake to exhaust discharge. up-to-date starting point.

Engine developers often need to match a new turbocharger to an existing engine. After building a baseline model calibrated with UPD, they replace the compressor and turbine maps. The UPD ensures that the combustion behavior remains correct even when boost pressure and flow change. The simulation then predicts how the engine’s torque curve, air–fuel ratio, and exhaust temperature respond to the new turbocharger, allowing optimal selection without costly dyno testing.
