Stringent emission and GHG regulations drive Diesel engine manufactures to improve hardware and control strategies every model year, lead to increasing calibration development time and cost. Although physics based models has been used in industry for decades, due to accuracy deficiency and high computational time, the usage is still limited to initial design and research phase. In order to fully utilize physics based model’s potential in calibration development with minimal data, improved techniques been shown to overcome those limitations in this paper. Phenomenological combustion and emission models along with air path dynamics are developed in GT-Suite using steady state points over engine operation area. Models are validated using data with limited data corresponding to variation in actuators and Calibration parameters to understand any limitations of using models over wide range of variations.
