Abstract: Demand for better fuel efficiency in automotive industry is ever growing. Clear trade‐off between the efficiency and emissions has been posing a significant challenge, especially with emission standards being more stringent, too. Computational modeling and analysis has become an element in development process, because it helps expedite project and save resource. High performance computing environment enables high fidelity models run faster. Computational design optimization over a vast design space is becoming a common practice. System level model development with component model integration is a key to leverage the progress and to further the capability.

Bio: Chang‐Wook Lee is the Powertrain Simulation Manager at PACCAR Technical Center. He is responsible for modeling and analysis for engine, after‐treatment system, drivetrain and vehicle fuel economy predictions to support other divisions. He has more than 20 years of experience in IC engine and truck field, covering testing, design and analysis across academia and industry. After completing M.S. and B.S. at Sungkyunkwan University in Korea, he worked for Hyundai‐Kia Motor Company for 6 years and half. Then, he went to University of Cambridge for his Ph.D. in turbulent combustion modeling. He was a post‐doc and Assistant Scientist at University of Wisconsin‐Madison / Engine Research Center before working on combustion modeling at Cummins for years. He has been with PACCAR for five years and is interested in component and system optimization for better truck efficiency.
