GT-Power and GT-Suite

GT-Power Software Package GT-POWER:

It is the industry standard engine performance simulation, used by all major engine manufacturers and vehicle OEMs, conceived and developed by Gamma Technologies Inc. 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 for SiL or HiL simulations [1]. 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.

GT-SUITE: GT-Suite can be used for modeling each system independently or for coupling several systems together to make them interact with each other, so more complex systems can be analyzed. Gamma Technologies uses licensing system to give access to different components in GT-Suite. Initially the licenses were named according to the template databases they were providing access to. Starting from GT-Suite version 7.0 the licenses GT-COOL, GT-FUEL, GT-CRANK, GT-VTRAIN, and GT-DRIVE were all absorbed into a single license type called GT-SUITEmp. GT-POWER still has its own license type. In addition, there is a license called GT-SUITE that combines licenses GT-SUITEmp and GT-POWER, therefore covering all available components and providing access to all template libraries [4].

Applications of GT-Power GT-POWER contains the most comprehensive and advanced set of models for engine performance analysis, providing the breadth of features required to allow the engineer to analyze a number of engine configurations and performance characteristics, including: 	Torque and power curves, airflow, vol. efficiency, fuel consumption, emissions. 	Steady state or full transient analysis, under any driving scenario. 	Turbocharged, supercharged, turbocompound, e-boost, pneumatic assist. 	SI, DI, HCCI and multi-mode combustion, multi-fuel, and multi-pulse injection. 	Infinitely variable valve timing and lift (VVT and VVL). 	Acoustic analysis of intake and exhaust systems. 	Manifold and cylinder component thermal analysis, with included FE solver. 	Controls system modeling, via built-in controls library or Simulink coupling.
