Thermodynamic engine cycle and gas exchange simulation


  • Prediction and optimization of intake and exhaust systems
  • Combustion, emission, and acoustic analysis
  • Perforated pipe elements for accurate exhaust system models
  • Steady-state and transient calculations
  • Vehicle thermal management
  • Co-simulation with MATLAB and Simulink using DLL, API, or S-functions


AVL BOOST is engine cycle and gas exchange simulation software that enables you to build a model of the entire engine by selecting elements from a toolbox and connecting them by pipe elements. These elements include cylinders, air cleaners, catalysts, intercoolers, turbochargers, advanced junction models, and many more. Within the pipes, one-dimensional gas dynamics are considered. An adapted Godunov - Scheme ensures a high accuracy of the solution. BOOST can simulate steady-state operating points as well as engine transients.

BOOST is used in both the automotive and nonautomotive industries for accurate engine simulation. It has been used for modeling a wide range of engine speeds and sizes, including two-stroke and four-stroke engines. In the BOOST engine model, numerical outputs (sensors) can provide values, such as pressure, temperature, air/fuel ratio, and many more, at measuring points in the simulation model. These can be used as input to a Simulink model of the engine control unit (ECU). Signals can be passed into BOOST (actuators) to control parameters such as throttle position or vane position for a variable geometry turbocharger.
