GT-POWER Engine Simulation Software
Engine Perfomance Analysis Modeling
See the Engine Performance Brochure (PDF)
GT-POWER is the market leading engine simulation software, used by every major engine
manufacturer for the design and development of their engines. It is applicable to all
sizes and types of engines, and its installed base includes a highly diverse group of car,
truck, motorcycle, motor sport, marine, locomotive, power generation, mining and
construction, agricultural, and lawn and garden equipment manufacturers.
GT-POWER contains the industry’s 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:
o Torque and power curves, airflow, vol. efficiency, fuel consumption, emissions
o Steady state or full transient analysis, under any driving scenario
o Turbocharged, supercharged, turbocompound, e-boost, pneumatic assist
o SI, DI, HCCI and multi-mode combustion, multi-fuel, and multi-pulse injection
o Infinitely variable valve timing and lift (VVT and VVL)
o Acoustic analysis of intake and exhaust systems
o Manifold and cylinder component thermal analysis, with included FE solver
o Controls system modeling, via built-in controls library or Simulink coupling
Unmatched Model Accuracy
GT-POWER has long been recognized for its high degree of accuracy in predicting the
behavior of complex engine related phenomena. At its core, the GT-POWER solver is based
on the 1D solution of the fully unsteady, nonlinear Navier-Stokes equations. Beyond this core
lie state of the art thermodynamic and phenomenological model solvers to capture the effects
of combustion, heat transfer, evaporation, in-cylinder motion and turbulence, and engine and
tailpipe out emissions, to name just a few. This combination of solvers provides for unmatched
model accuracy for both macro level quantities such as torque, bsfc, airflow, etc., as well as
detailed micro level quantities such as crankangle resolved cylinder pressure resulting from
multi-pulse injection strategies, as well as emission specie concentrations anywhere in the
system.
Beyond Basic Cycle Simulation
GT-POWER is licensed as an all-inclusive package containing many advanced modeling
features not found in other engine simulations. A full FE solver for in-cylinder
temperature and heat flux distribution, as well as a complete, fully flexible, detailed
chemical kinetics and aftertreatment library are just two of the many advanced modeling
capabilities included with GT-POWER at no extra cost.
