Professor Yi Yang is a Professor in the Department of Mechanical Engineering at the University of Melbourne, within the Faculty of Engineering and Information Technology. He received his PhD from Pennsylvania State University. His research focuses on combustion chemistry, autoignition, engine and fuel interactions, and low-emission technologies. Yi Yang's work addresses critical challenges in decarbonizing combustion engines through advanced concepts such as homogeneous charge compression ignition (HCCI), hydrogen and ammonia fuel utilization, and biofuel blending.

Key publications demonstrate his influence in the field. These include 'Boosted HCCI for high power without engine knock and with ultra-low NOx emissions using conventional gasoline' (2010, SAE International Journal of Engines), 'The octane numbers of ethanol blended with gasoline and its surrogates' (2014, Fuel), 'Boosted HCCI—controlling pressure-rise rates for performance improvements using partial fuel stratification with conventional gasoline' (2011, SAE International Journal of Engines), 'Tailoring HCCI heat-release rates with partial fuel stratification: Comparison of two-stage and single-stage-ignition fuels' (2011, Proceedings of the Combustion Institute), and 'A study of jet fuel sooting tendency using the threshold sooting index (TSI) model' (2007, Combustion and Flame). Recent efforts explore hydrogen-blended fuels, nitric oxide effects on knock, and high-pressure plug flow reactors for combustion studies. Professor Yang supervises doctoral students investigating cryogenic hydrogen experiments, ammonia autoignition, and dynamic route optimization. He delivers courses such as Thermodynamics (MCEN90015) and Advanced Thermodynamics (MCEN90019). As part of a University of Melbourne team, he contributes to the ARC Centre of Excellence for Renewable Fuels, advancing renewable fuel technologies for transport decarbonization. His experimental investigations and collaborations have shaped understanding of fuel autoignition and emission control strategies.
