GT-POWER Engine Simulation Software
GT-POWER is the industry standard engine performance simulation, used by all major engine manufacturers and vehicle OEMs. GT-POWER is used to predict engine performance quantities such as power, torque, airflow, volumetric efficiency, fuel consumption, turbocharger performance and matching, and pumping losses, to name just a few. Beyond basic performance predictions, GT-POWER includes physical models for extending the predictions to include cylinder and tailpipe-out emissions, intake and exhaust system acoustic characteristics (level and quality), in-cylinder and pipe/manifold structure temperature, measured cylinder pressure analysis, and control system modeling. Standard GT-POWER engine models are easily converted to real-time capable models (also known as Fast Running Models – FRMs) for SiL or HiL simulations. These models may also be included in a full system level simulation within GT-SUITE to provide accurate and physically based engine boundary conditions to the rest of the vehicle.
