State-of-the-Art Combustion Models
Highly accurate, fully predictive, multi-pulse diesel and tumble sensitive, turbulent SI combustion models
Simulate engine performance, gas exchange, and combustion with GT-POWER's industry-leading 1D engine modeling for accurate, predictive results
Solution Overview
WHAT IS GT-POWER?
GT-POWER is the industry standard internal combustion engine performance simulation software, used by all major engine manufacturers and vehicle OEMs. GT-POWER is a very commonly used name for engine performance simulation in GT-SUITE. It is used to predict engine performance quantities such as power, torque, fuel consumption, turbocharger performance and matching, to name just a few. It became established as a standard in the engine industry as the go-to tool used to optimize valve and cam lift profiles and timings, determine optimal intake and exhaust manifold designs and select turbochargers virtually.
