GT-POWER, an engine and powertrain simulation software, is developed by Gamma Technologies. GT-POWER is one of the products offered within the GT-SUITE simulation environment.[1] The software uses a one-dimensional (1D) system modeling approach to primarily study engine gas exchange, combustion, thermodynamic behavior, heat transfer, emissions, acoustics, and interactions among engine and powertrain components.[2]
Academic research
[edit]GT-POWER has been used in academic research for engine performance analysis, component design, combustion and emissions modeling, alternative-fuel evaluations, and optimization. Researchers commonly compare individual GT-POWER models with experimental data for further analysis and identifying model limitations. [2]
A study developed a model for a single-cylinder gasoline engine and evaluated the model for brake torque, brake power, brake-specific fuel consumption, and brake thermal efficiency. The researchers evaluated the model against experimental data before comparing the effects of different types of gasoline fuels across different engine RPMs.[3]
Another study developed a GT-POWER model of a 2.0-liter turbocharged gasoline engine with emphasis on valve timing, intake airflow, and turbocharger matching. The model was calibrated using prototype data and applied across operating points to evaluate development targets.[4]
Co-simulation
[edit]Co-simulation connects GT-POWER with other simulation tools like MATLAB/Simulink. Each program can represent a different part of the engine model, or a larger engineering system. GT-POWER can provide the 1D physical engine model, while other tools provide control logic or models of the other parts of the system.
Researchers developed a 1D spark-ignition-engine model in GT-POWER and validated it against experimental gasoline-engine data. The validated model was coupled with MATLAB/Simulink to determine a suitable ethanol-gasoline blend ratio for different engine speeds. The study found that optimal ethanol fraction increased with higher engine speeds.[5]
In another study, researchers modeled a hydrogen-fueled hydraulic-engine system. GT-POWER modeled the internal-combustion engine, AMESim modeled the synchronous plunger pump, and Simulink facilitated the data exchange between the models. The integrated model was used to analyze energy distribution and the effects of hydraulic-load pressure and other operating conditions.[6]
Advantages and limitations
[edit]The 2025 Energies review compared GT-POWER's 1D modeling approach with three-dimensional (3D) tools such as CONVERGE CFD, ANSYS Fluent, and AVL FIRE. The review associated with GT-POWER's approach with lower computational time, which allowed for the software to run repeated simulations more quickly. The lower computing requirements also make GT-POWER suitable for on parametric studies, system-level analysis, and initial engine design. While the review compared these tools, it provided a general comparison of their individual modeling approaches rather than a controlled benchmark test across each tool. [2]
Compared against 3D CFD tools, GT-POWER's 1D approach provides less spatial detail for local flow structures, turbulence, complex geometry, multiphase interactions, and detailed combustion behavior. The 2025 Energies review also noted that there were significant time investments in setting up comprehensive GT-POWER models, and the models require accurate input data. Detailed 3D tools may supplement a GT-POWER model when 3D effects are important to engine analysis. [2]
